     DETAILED DESCRIPTION 
     In accordance with various embodiments, mechanisms (which can include methods, systems, and media) for providing dynamic media sessions with video stream transfer features are provided. 
     In some embodiments, the mechanisms described herein can be used to transfer presentation of a video content item from a first display device to a second display device. In some embodiments, the first display device and the second display device can be any suitable type(s) of devices capable of presenting video content, such as a television, a smart television, a display connected to a streaming media device, a game console, a vehicle entertainment system, a mobile device (e.g., a mobile phone, a wearable computer, a tablet computer, a laptop computer, a desktop computer, and/or any other suitable mobile device), a virtual assistant device with a screen, and/or any other suitable type of display device. 
     In some embodiments, the mechanisms can cause presentation of the video content item to be transferred from the first display device to the second display device in response to any suitable information. For example, in some embodiments, a user device (e.g., a mobile phone, a virtual assistant device, a tablet computer, a wearable computer, and/or any other suitable device) that is used to control presentation of the video content item on the first display device can receive an indication that presentation of the video content item is to be transferred to the second display device. As a more particular example, in some embodiments, the user device can receive the indication via one or more user interfaces, as shown in and described below in more detail in connection with  FIGS. 1, 2A, and 2B . 
     In some embodiments, the mechanisms described herein can identify available display devices and can present the identified display devices for selection by a user. For example, in some embodiments, available display devices (e.g., “bedroom television,” “den television,” “kitchen smart display,” etc.) can be identified and can be presented as available display devices to which presentation of a video content item can be transferred. In some embodiments, available display devices can be identified and presented for selection by a user in any suitable manner, as shown in and described below in connection with  FIGS. 1, 2A, and 2B . 
     In some embodiments, the mechanisms described herein can transfer playback of the video content item from the first display device to the second display device in any suitable manner. For example, as described below in more detail in connection with  FIGS. 1 and 3 , in some embodiments, transfer of playback of the video content item can be performed using a server associated with a media content casting service. In such embodiments, the server can store information associated with a media playback session on one or more display devices. In some embodiments, the server can transfer playback of the video content item that is being presented as part of a media playback session from a first display device to a second display device in any suitable manner. For example, in some embodiments, the server can transmit an instruction to the first display device to stop presenting the video content item in connection with a request for the first display device to return, to the server, a current playback state that includes a playback position at which presentation of the video content item on the first display device is stopped. Continuing with this example, in some embodiments, the server can then transmit, to the second display device, an indication of the current playback state in connection with instructions that cause the second display device to begin presenting the video content item from a playback position that is determined based on the playback position included in the current playback state. Accordingly, the second display device can resume playback of the video content item using an instance of a media playback application based on the current playback state of the first display device. 
     Turning to  FIG. 1 , an illustrative example  100  of a process for providing dynamic media sessions with video stream transfer features is shown in accordance with some embodiments of the disclosed subject matter. In some embodiments, blocks of process  100  can be executed by a user device from which presentation of media content on different media presentation devices (e.g., different display devices, different speakers, and/or any other suitable media presentation devices) can be controlled. For example, in some embodiments, the user device can be a mobile phone, a tablet computer, a wearable computer, a laptop computer, a desktop computer, a virtual assistant device, and/or any other suitable type of user device. 
     At  102  of process  100 , the user device can cause a video content item to begin being presented on a first display device. In some embodiments, the first display device can be any suitable type of media presentation device that is capable of presenting video content, such as a smart television, a television coupled to a streaming media device that receives instructions from the user device, a game console, a virtual assistant device with a screen, and/or any other suitable display device. In some embodiments, the user device can communicate with the first display device in any suitable manner. For example, in some embodiments, the user device and the first display device can transmit and receive messages via a Wi-Fi network the user device and the first display device are both connected to. As another example, in some embodiments, the user device and the first display device can communicate via a BLUETOOTH network. 
     In some embodiments, the user device can cause the video content item to begin being presented on the first display device in any suitable manner. For example, in some embodiments, the user device can transmit a link to the video content item to the first display device that instructs the first display device to request or retrieve video content associated with the link and begin presenting the video content. Note that, in some embodiments, the video content item can be any suitable type of video content item (e.g., a video, a music video, a movie, a television show, live-streamed video content, and/or any other suitable type of video content item). In some embodiments, the video content item can be a video content item that is stored on a server (e.g., a server associated with a video sharing service, a server associated with a social networking service, and/or any other suitable server) that is streamed from the server by the first display device. 
     Note that, in some embodiments, the first display device can present the video content item using any suitable application that is executing on the first display device. For example, in some embodiments, the first display device can present the video content item using an application associated with a video sharing service, where the application causes a video player window in which the video content is played back to be presented on the first display device. In some embodiments, the first display device can initialize such an application in response to receiving an instruction from the user device. 
     In some embodiments, the user device can present a user interface that allows a user of the user device to control presentation of the video content item on the first display device. Turning to  FIG. 2A , an illustrative example  200  of a user interface for controlling and interacting with presentation of the video content item is shown in accordance with some embodiments of the disclosed subject matter. As illustrated, in some embodiments, user interface  200  can include video information  202 , video content  204 , a display device indicator  206 , a video playback indicator  208 , and/or playback controls  209 . 
     In some embodiments, video information  202  can indicate a title of the video content item, such as shown in  FIG. 2A . In some embodiments, video information  202  can include any other suitable information about the video content item, such as a channel to which the video content item was uploaded and/or is otherwise associated, a name of a creator of the video content item, a date associated with the video content item (e.g., a date the video content item was created, a date the video content item was uploaded to a video sharing service or other service, and/or any other suitable date), and/or any other suitable information. 
     In some embodiments, video content  204  can include any suitable images associated with the video content item. For example, in some embodiments, video content  204  can include a thumbnail image that represents the video content item being presented on the first display device. 
     In some embodiments, display device indicator  206  can include any suitable information, such as a name of the first display device (e.g., “living room TV,” “mobile phone,” “bedroom TV,” and/or any other suitable name). In some embodiments, display device indicator  206  can include any suitable icon(s) that indicates any suitable information, such as a type of device associated with the first display device (e.g., that the first display device is a television, that the first display device is a game console, and/or any other suitable device type information), an indication of an owner of the first display device (e.g., an icon that includes an initial of the owner, an image that includes a profile photo of the owner, and/or any other suitable owner indication), and/or any other suitable information. Note that, in some embodiments, display device indicator  206  can be selectable. In such embodiments, in response to determining that display device indicator  206  has been selected, the user device can present a user interface that allows a different display device to be selected to transfer content to the selected display device, as shown in and described below in connection with  FIG. 2B  and blocks  104 - 108  of  FIG. 1 . 
     In some embodiments, video playback indicator  208  can indicate a duration of the video content item and/or how much of the video content item has elapsed at a current time, as shown in  FIG. 2A . 
     In some embodiments, user interface  200  can include playback controls  209  that can be used to modify playback of the video content item. As a more particular example, in some embodiments, as shown in  FIG. 2A , user interface  200  can include a rewind button, a pause button, and/or a fast-forward button. In some embodiments, user interface  200  can additionally or alternatively include volume controls that can be used to adjust a volume of audio content associated with the video content item. 
     Referring back to  FIG. 1 , at  104  of process  100 , the user device can receive an indication that presentation of the video content item is to be transferred to a second display device. In some embodiments, the user device can receive the indication in any suitable manner. For example, in some embodiments, the user device can receive the indication via a user interface, such as user interface  200  as shown in and described above in connection with  FIG. 2A . As a more particular example, in some embodiments, the user device can receive the indication in response to determining that display device indicator  206  as shown in  FIG. 2A  has been selected. As another more particular example, in some embodiments, user interface  200  can include a selectable icon that, when selected, indicates that presentation of the video content item is to be transferred to a different display device. 
     It should be noted that, in some embodiments, the user device can determine whether the video content item can be transferred to a second display device. For example, the user device can determine whether the video content item is associated with a particular type of content and, in response to determining that the video content item is associated with a particular type of content (e.g., movie content, subscription-based content, premium content, content associated with a particular type of media service, etc.), the user device can proceed to  106  of process  100 . In another example, the user device can determine whether the video content item is being presented using a media playback application that is capable of supporting the transfer of the video content item to the second display device. In a more particular example, the user device can determine whether the media playback application used to present the video content item on the user device supports stream transfer of the video content item and the user device can determine whether the user device can be removed as the device that presents the video content item. Accordingly, in response to the user determining that the video content item cannot be transferred to the second display device, the user device can prevent the video content item from being transferred. 
     At  106  of process  100 , the user device can identify one or more candidate display devices capable of presenting the video content item. In some embodiments, the user device can identify the one or more candidate display devices in any suitable manner and using any suitable technique(s). For example, in some embodiments, the user device can use any suitable device discovery protocol to identify the one or more candidate display devices connected to a same communication network that the user device is connected to, such as a local Wi-Fi network in a home of a user of the user device, and/or any other suitable communication network. As a more particular example, in some embodiments, the user device can identify the one or more candidate display devices via mDNS, Discovery and Launch (DIAL), and/or using any other suitable protocol(s). Note that, in some embodiments, an identified display device can be connected to a Wi-Fi network directly or via a streaming media interface that is connected (e.g., via an HDMI connection, and/or connected in any other suitable manner) to the display device. 
     In some embodiments, the user device can identify one or more display devices using any suitable device discovery protocol and can subsequently determine whether each of the discovered display devices is capable of receiving a transfer of presentation of the video content item. In some embodiments, the user device can determine whether each identified display device is capable of being a candidate display device based on any suitable information, such as based on a type of device of the identified display device, a capability of the identified display device, subscription information, and/or any other suitable information, as described in more detail below. 
     In some embodiments, the user device can identify any suitable information about each of the one or more identified display devices. For example, in some embodiments, the user device can determine a type of device associated with each of the identified display devices. As a more particular example, in some embodiments, the type of device can indicate that the identified display device is a television, that the identified display device is a streaming media device connected to a television, that the identified display device is a virtual assistant device with a screen, and/or any other suitable type of device. As another example, in some embodiments, the user device can determine a capability of each of the identified display devices. As a more particular example, in some embodiments, the user device can determine whether each identified display device is capable of receiving instructions from the user device and/or from a server associated with a media casting session (e.g., instructions to initialize a particular application for presenting video content, instructions that include a playback position, and/or any other suitable instructions). As another more particular example, in some embodiments, the user device can determine whether each identified display device is updated with a particular version of an application to be used for presenting the video content item. As yet another example, in some embodiments, the user device can identify a model number of each identified display device. 
     In some embodiments, the user device can determine a proximity of each identified display device to the user device. For example, in some embodiments, the user device can determine that a first identified device (e.g., a bedroom television) is closer to the user device than a second identified device (e.g., a kitchen smart display). 
     In some embodiments, the user device can additionally determine whether a user of the user device has purchased a particular subscription with a service used for playing, downloading, or streaming the video content item. For example, in some embodiments, the user device can determine whether the user has purchased a premium subscription that allows the user to transfer presentation of a video content item from one display device to another. In some embodiments, the user device can determine whether the user has purchased a particular type or level of subscription in any suitable manner. For example, in some embodiments, the user device can transmit a query to a server associated with a service that provides the video content item, where the query requests account information corresponding to a user account of the user. Note that, in some embodiments, the user device can store account information that indicates whether the user has purchased a particular subscription or a particular level of subscription to the service. 
     In some embodiments, the user device can then determine whether each identified display device is capable of being included in the candidate display devices based on the information associated with each identified display device (e.g., device type information, capability information, and/or any other suitable device information) and/or the subscription information. For example, in some embodiments, the user device can determine that an identified display device that is not updated with a particular version of a particular application is not to be included in the candidate display devices. As another example, in some embodiments, the user device can determine that none of the identified display devices are to be included in the candidate display devices in response to determining that the user has not purchased a particular subscription or level of subscription. 
     At  108  of process  100 , the user device can present a user interface that indicates the identified candidate display devices. Turning to  FIG. 2B , an example  250  of a user interface that indicates candidate display devices is shown in accordance with some embodiments of the disclosed subject matter. As illustrated, in some embodiments, user interface  250  can include a stop presentation button  252 , a volume indicator  254 , and a group of identified candidate display devices  256 . 
     In some embodiments, stop presentation button  252  can, in response to being selected, cause presentation of the video content item to stop on the first display device. Note that, in some embodiments, stop presentation button  252  can be omitted. 
     In some embodiments, volume indicator  254  can indicate a current volume of audio content associated with the video content item being presented by the first display device. For example, as shown in  FIG. 2B , volume indicator  254  can include a percentage that indicates a current volume relative to a maximum volume possible by the first display device. Additionally, as shown in  FIG. 2B , volume indicator  254  can include a slider that can be used to adjust a volume of the audio content on the first display device. 
     In some embodiments, group of identified candidate display devices  256  can include any of the one or more display devices identified as described above in connection with block  106 . For example, as shown in  FIG. 2B , group of identified candidate display devices  256  can include a bedroom television  258  and a kitchen smart display  259 . Note that, although two candidate display devices are shown in group of identified candidate display devices  256 , in some embodiments, any suitable number (e.g., one, two, five, ten, and/or any other suitable number) of display devices can be indicated. 
     Note that, in some embodiments, any suitable error message can be presented in place of group of identified candidate display devices  256  or in connection with a particular display device. For example, in some embodiments, in an instance in which no candidate display devices have been identified at block  106 , an error message can be presented that indicates that no display devices were found. As another example, in some embodiments, in an instance in which the user device determined that a user of the user device has not purchased a particular type of subscription that is required for transferring presentation of a video content item, an error message that indicates that purchase of a subscription is required can be presented. In such embodiments, the error message can include a link that, when selected, causes the user device to navigate to a page for purchasing a subscription to the service. As yet another example, in some embodiments, in an instance in which a particular display device has been identified by the user device, and in which it has been determined that the particular display device is not to be included as a candidate display device because the user of the user device has not purchased a particular subscription or level of subscription, the identified display device can be included in group of identified candidate display devices  256  in a manner that indicates that the display device has been identified but is not currently available for transfer of a presentation of video content. As a more particular example, in some embodiments, the identified display device can be listed in group of identified candidate display devices  256  with the name or identifier of the identified display device grayed out and/or presented in any other suitable visual manner that indicates that the display device is not currently available as a display device. Note that, in some embodiments, such an identified display device can be presented in connection with a link that, in response to being selected, can cause the user device to navigate to a page for purchasing the subscription or the level of subscription required to include the identified device as available for transfer of a presentation of video content. 
     In some embodiments, each display device in group of identified candidate display devices  256  can be associated with a selection button, such as selection button  262 . In some embodiments, selection of selection button  262  can cause the corresponding display device to be identified by the user device as a selected display device, as described below in connection with block  110  of  FIG. 1 . Note that, in some embodiments, selection buttons associated with each candidate display button can be a radio button or similar user interface control that allows only one candidate display device to be selected from group of identified candidate display devices  256 . 
     Note that, in some embodiments, the display devices included in the group of identified candidate display devices can be presented in any suitable order. For example, in some embodiments, the display devices can be presented in alphabetical order. As another example, in some embodiments, the display devices can be presented in order of proximity to the user device. As a more particular example, in some embodiments, candidate display devices that are determined to be closer to the user device can be presented in a higher position within group of identified candidate display devices  256 . 
     Referring back to  FIG. 1 , note that, although the indication that presentation of the video content item is to be transferred to a second display device (e.g., as described above in connection with block  104  of  FIG. 1 ) and selection of the second display device (e.g., as described above in connection with  FIG. 2B ) are described as received via user interfaces, in some embodiments, the indication that presentation of the video content item is to be transferred to a different display device and selection of the second display device can be received by the user device via a spoken command received using a microphone of the user device. For example, in some embodiments, the indication that presentation of the video content item is to be transferred to a second display device can be received by the user device in response to the user device detecting that particular trigger words have been received by the user device, such as “move to,” “play this on,” and/or any other suitable trigger word(s). As another example, in some embodiments, selection of the second display device can be received by the user device when the user device detects that an identifier of the second display device has been spoken, such as “bedroom television,” “kitchen smart display,” and/or any other suitable display device identifier(s). 
     Referring back to  FIG. 1 , in some embodiments, at  110  of process  100 , the user device can receive a selection of one of the display devices via the user interface as the second display device. For example, in some embodiments, the user device can determine that a selection button corresponding to a particular candidate display device has been selected, as shown in and described above in connection with  FIG. 2B . 
     At  112  of process  100 , the user device can transmit, to a server, an indication that presentation of the video content item is to be transferred to the selected second display device. In some embodiments, the server can be any suitable server. For example, in some embodiments, the server can be associated with a media casting session service that stores any suitable information associated with a casted media playback session in which the video content item is currently being presented by the first display device, as described in more detail in connection with  FIGS. 3 and 4 . In some embodiments, the user device can transmit any suitable information to the server, such as an identifier of the second display device, an identifier of the video content item that is being presented by the first display device, an identifier of the first display device, and/or any other suitable information. 
     Note that, in some embodiments, in response to receiving the indication from the user device, the server can perform any suitable actions that transfer presentation of the video content item to the second display device, as shown in and described below in connection with  FIG. 3 . Additionally, note that, in some embodiments, the server can cause the first display device to stop presentation of the video content item at a particular playback position, as described below in more detail in connection with  FIG. 3 . 
     At  114  of process  100 , the user device can determine whether the selected second display device is the user device itself. 
     If, at  114 , the user device determines that the selected second display device is not the user device itself (“no” at  114 ), the user device can, at  116  of process  100 , present a user interface for controlling playback of the video content item on the second display device. In some embodiments, the user interface can be similar to user interface  200  as shown in and described above in connection with  FIG. 2A . In some embodiments, the user interface can include any suitable user interface controls for modifying playback of the video content item on the second display device, such as a rewind button, a pause button, a fast-forward button, and/or any other suitable user interface controls, as shown in and described above in connection with  FIG. 2A . In some embodiments, the user interface can include an indication of the second display device. 
     If, at  114 , the user device determines that the second display device is the user device itself (“yes” at  114 ), the user device can, at  118  of process  100 , load an application for presenting the video content item. In some embodiments, the application can be any suitable application. For example, in some embodiments, the application can be associated with a video sharing service that provides the video content item being presented. 
     At  120  of process  100 , the user device can begin presenting the video content item. In some embodiments, the user device can begin presenting the video content item from a playback position corresponding to a time point at which the first display device stopped presentation of the video content item. Note that, in some embodiments, the user device can begin presenting the video content item using any suitable technique(s). For example, as described below in more detail in connection with  FIG. 3 , in some embodiments, the user device, functioning as the selected second display device, can receive, from the server, information associated with the media playback session. As a more particular example, in some embodiments, the information associated with the media playback session can include an identifier of the video content item being presented and an indication of a playback position from which the user device is to begin presenting the video content item. Continuing with this example, in some embodiments, the user device can then begin presenting the video content item from the indicated playback position in any suitable manner. For example, in some embodiments, the user device can request that a server that hosts the video content item begin streaming the video content item to the user device from the indicated playback position. Note that, in such embodiments, the server that hosts the video content item can be different than or the same as the server that coordinates transfer of playback of the video content item between the first display device and the second display device. 
     It should be noted that, in some embodiments in which the second display device is a leader device of a group of devices including one or more follower devices, the second display device can receive information associated with the media playback session, such as an identifier of the video content item being presented and an indication of a playback position from which the second display device is to begin presenting the video content item, and can transmit instructions to each of the follower devices that cause the follower devices to present audio content associated with the video content item synchronously with the second display device. 
     Turning to  FIG. 3 , an example  300  of a process for transferring presentation of a video content item from a first display device to a second display device is shown in accordance with some embodiments of the disclosed subject matter. In some embodiments, blocks of process  300  can be executed by a server, such as a server that stores information associated with casted media playback sessions. 
     At  302  of process  300 , the server can receive, from a user device, an indication that presentation of a video content item is to be transferred from a first display device to a second display device. As described above in connection with  FIG. 1 , in some embodiments, the video content item can be any suitable type of video content, such as a television show, a movie, a video, live-streamed video content, a video in a playlist of videos, and/or any other suitable type of video content item.

     In some embodiments, the indication can include any suitable information. For example, in some embodiments, the indication can include identifiers of the first display device and/or the second display device. As a more particular example, in some embodiments, the identifiers can include any suitable identifying information, such as network information associated with the first display device and/or the second display device (e.g., IP addresses, port information, MAC addresses, and/or any other suitable network information), a make or model of the first display device and/or the second display device, and/or any other suitable identifying information. As another example, in some embodiments, the indication can include an identifier of a media playback session associated with presentation of the video content item. As yet another example, in some embodiments, the indication can include an identifier of the video content item (e.g., a URL at which the video content item is located, a name of the video content item, and/or any other suitable identifying information). 
     At  304  of process  300 , the server can transmit instructions to the second display device to initialize an application for presenting the video content item. In some embodiments, the application can be any suitable application. For example, in some embodiments, the application can be associated with a particular video sharing service, a particular media content presentation service, a particular social networking service, and/or any other suitable application. In some embodiments, the application can cause video content to be presented on a device executing the application, for example, in a video player window presented within a user interface of the application. In some embodiments, the application can be an application that can manage presentation of the video content item on the second display device in any suitable manner. For example, in some embodiments, the application can control a video pipeline used to present video content on a display of the second display device. As another example, in some embodiments, the application can control an audio pipeline used to present audio content associated with the video content item using speakers associated with the second display device. Note that, in some embodiments, an instance of the application can be currently executing on the first display device in connection with presentation of the video content item on the first display device. 
     At  306  of process  300 , the server can transmit, to the first display device, an instruction to stop presentation of the video content item and a request for a current playback session state that indicates a playback position at which presentation of the video content item was stopped on the first display device. In some embodiments, the instruction to stop presentation of the video content item can include any suitable instructions or commands. For example, in some embodiments, the instruction can include commands to stop presenting video content and audio content associated with the video content item by the first display device. As another example, in some embodiments, the instruction can include commands to relinquish any suitable resources used by the first display device, such as screen resources, audio presentation resources, and/or any other suitable resources. As yet another example, in some embodiments, the instruction can include commands to close or stop execution of an application executing on the first display device for presentation of the video content item. 
     At  308  of process  300 , the server can receive, from the first display device, the current playback session state in response to the request. In some embodiments, the current playback session state can include any suitable information, such as an indication of a playback position at which presentation of the video content item was stopped on the first display device. For example, in some embodiments, the playback position can indicate a time point of the video content item at which presentation of the video content item was stopped on the first display device. As another example, in some embodiments, the playback position can indicate a last frame of the video content item that was presented by the first display device prior to stopping presentation of the video content item on the first display device. Additionally, in some embodiments, the server can receive, from the first display device, a content URL associated with the video content item, a current time or playback position of the video content item being played back on the first display device, a queue structure, user credentials associated with the media playback application used to present the video content item, etc. 
     At  310  of process  300 , the server can transmit the current playback session state to the second display device in connection with instructions that cause the second display device to begin presenting the video content item based on the playback position included in the current playback session state. In some embodiments, the instructions can cause the second display device to begin presenting the video content item based on the playback position in any suitable manner. For example, in some embodiments, the instructions can cause the second display device to begin presenting the video content item at a playback position subsequent to the playback position included in the current playback session state. As a more particular example, in some embodiments, the instructions can cause the second display device to begin presenting the video content item from a frame subsequent to a last frame that was presented by the first display device. As another more particular example, in some embodiments, the instructions can cause the second display device to load a media playback application and resume the presentation of the video content item using the media playback application having the same application identifier and at a current playback position based on the current playback session state. As another example, in some embodiments, the instructions can cause the second display device to begin presenting the video content item from a playback position that precedes the playback position included in the current playback session state (that is, preceding a playback position at which presentation of the video content item was stopped on the first display device). In such embodiments, the instructions can cause the second display device to begin presenting the video content item from a playback position that precedes the playback position included in the current playback session state by any suitable duration (e.g., three seconds, five seconds, and/or any other suitable duration) and/or number of frames (e.g., thirty frames, sixty frames, and/or any other suitable number).
