## Title
Adding video effects for video enabled applications

## Abstract

A streaming video interface component receives video frames from a streaming driver before the frames are received by a consuming application. The streaming video interface component provides the video frames to a video effect rendering component which renders video effects selected by a user. The video frames with the rendered video effects are then provided back to the streaming interface component which thereafter provides them to the consuming application.

## Background
BACKGROUND
Video cameras are currently in wide use. Similarly, video cameras are currently being widely used as peripheral devices to computers, and especially personal computers.
While there are a wide variety of applications which make use of cameras on computers, some include simply capturing live video images. Others include conducting surveillance. Still others use the camera for messaging, such as for conducting video instant messaging or video calls from a computer. In fact, it is becoming increasingly popular for users of cameras, connected to computers, to use those systems to talk to people (with both video and audio capability) around the world.
In each of these applications, it may be desirable to provide an enhanced user experience whereby a user can quickly and easily add video effects to an outgoing video stream so that the video effects appear as if they are being provided from the camera driver itself. It may also be desirable for the video effects to be displayed as if they are part of the original video stream, no matter what application they are eventually consumed by.
In some prior techniques, video effects were added to video frames by a consuming application. However, this requires generation and rendering of the video effects to be updated at each application, if the video effects are desired in that application. Processing video effects in this way can be undesirably expensive.
The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.
SUMMARY
A streaming video interface component receives video frames from a stream driver before the frames are received by a consuming application. The streaming interface component provides the video frames to a video effect rendering component which renders video effects, selected by a user. The video frames with the rendered video effects are then provided back to the streaming interface component which thereafter provides them to the consuming application.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

DETAILED DESCRIPTION
A large majority of applications that use video cameras as peripherals for computing devices rely on a streaming mode architecture for transmitting data from the camera to the user environment, and a user mode architecture that processes and consumes the video signal. Therefore, before describing the present invention in detail, one illustrative embodiment of a user mode architecture and a streaming mode architecture will be described. It will be noted that the invention is not limited to the particular streaming and user mode architectures described, but they are described for the sake of example only.
One exemplary embodiment of a streaming architecture is referred to as a kernel streaming architecture (KSA). As is known, a streaming subsystem in the kernel streaming architecture provides a high bandwidth and low latency communication mechanism between device drivers.
One illustrative user mode architecture divides the processing of multimedia tasks into a set of steps known as filters. Filters have a number of input and output pins, which connect them together to form a filter graph. A capture filter in the filter graph captures streaming data from a device, such as a camera or camera driver.
The kernel mode components of the kernel streaming devices communicate directly without transitions to and from the kernel mode, thereby achieving high bandwidth and low latency. Thus, the user mode architecture includes a user mode streaming proxy that uses device input/output (I/O) control commands to the kernel streaming subsystem to interact with the kernel streaming subsystem in order to stream data to and from the kernel streaming architecture.
FIG. 1 is a block diagram of one embodiment of a system 100 for adding video effects to a video stream. System 100 includes a kernel mode environment 102 and a user mode environment 104. Kernel mode environment 102 includes camera 106, camera driver 108 and kernel streaming driver 110. In the embodiment in which the kernel streaming architecture is used, kernel steaming driver 110 can be embodied as the known KS.sys component in the kernel streaming architecture.
User mode environment 104 includes application 112 with multimedia processing system 114. In one embodiment, multimedia processing system 114 is the DirectShow® multimedia processing system and API available from Microsoft Corporation of Redmond, Wash., although other processing systems can be used as well.
User mode environment 104 also includes kernel streaming proxy 116, video effect engine (VEE) kernel streaming interface handler 118, video effect rendering component 120, user selection component 122 and effects data store 124.
Application 112 can include any of a wide variety of applications. Examples include, for instance, a video capture application, a video surveillance application, an instant messaging application, a video calling application, etc.
Application 112 receives video data taken by camera 106. The video data is transmitted using high bandwidth, low latency, kernel streaming techniques in kernel streaming environment 102, through camera driver 108 and kernel streaming driver 110 to user mode environment 104. The streaming video data is received by the VEE kernel streaming interface handler 118. Interface handler 118 can be part of kernel streaming proxy 116 (as indicated by dashed box 117) or separate therefrom. In any case, interface handler 118 receives the video frames 130 and provides them to a video effect rendering component 120 that renders video effects on video frames 132. The video effects that are rendered were previously selected by user 132 through a user interface representation of user selection component 122.
User selection component 122 is illustratively a video effects manager that manages and enumerates video effect renderers available on the system, and provides application programming interfaces that can be used by a user interface to help user 132 select and apply video effects. User selection component 122 can illustratively be a separate application, such as a system tray application, or it can be a portion of application 112. This is indicated by block 136 shown in phantom in FIG. 1.
Effects data store 124 illustratively stores a plurality of different types of video effects that can be applied to the video frames received. Effects data store 124 can illustratively be accessed by component 122 and component 120. Data store 124 can store the visual effects in any desired way. Examples of some video effects that can be stored include foreground rendered effects, background substitution effects, fading, etc.
VEE kernel streaming interface handler 118 taps into the video pipeline and provides application programming interfaces to user selection component 122 so that user selection component 122 can indicate the effects which the user desires to apply.
Once the selected effects are rendered in the video frames by rendering component 120, the video frames with rendered video effects 134 are then provided back to interface handler 118 where they are provided up through user mode environment 104, through kernel streaming proxy 106 and to the multimedia processing system 114 in application 112. The video frames, with the rendered video effects, are processed by system 114.
FIG. 2 is a flow diagram better illustrating one embodiment of the operation of system 100 shown in FIG. 1. Application 112 is first started. This is indicated by block 150 shown in FIG. 2. Application 112 then generates the multimedia processing graph with multimedia processing system 114. For instance, in one embodiment, the filter graph is created when application 112 is started. Generating the multimedia processing graph is indicated by block 152 in FIG. 2. It is also described in greater detail with respect to FIG. 3 below.
Application then 112 begins playing the filter graph generated by multimedia processing system 114. This is indicated by block 156 in FIG. 2.
User 132 then selects video effects to be applied through user selection component 122. As briefly described above, component 122 illustratively provides a user interface which allows a user to search through and select various types of video effects that the user wishes to apply to the incoming video stream. An indication of which video effects have been selected is then communicated from user selection component 122 to VEE kernel streaming interface handler 118, such as through appropriate application programming interfaces. Selecting the video effects is indicated by block 154 in FIG. 2.
Kernel streaming proxy 116 then calls kernel streaming driver 110 to obtain video frames. The video frames are illustratively first generated by camera 106 and then provided through camera driver 108 to kernel streaming driver 110. Having kernel streaming proxy 116 request video frames from kernel streaming driver 110 is indicated by block 158 in FIG. 2.
In one embodiment, the call from kernel streaming proxy 116 to kernel streaming driver 110 is an asynchronous, call. In that embodiment, kernel streaming proxy 116 can then go on to perform any other desired functions performed by the particular filter that embodies kernel streaming proxy 116, without waiting for a return on the call. Of course, synchronous calls could be used as well.
Kernel streaming driver 110 then waits until a sufficient number of video frames are available to be transmitted to the user mode environment 104. Once a video frame is ready to be transmitted, kernel streaming driver 110 signals an event following which the kernel streaming proxy 116 calls kernel streaming interface handler 118. This is indicated by block 160 in FIG. 2.
Kernel streaming interface handler 118 then receives (either by pulling or by kernel streaming driver 110 pushing) the frames. This is indicated by block 162 in FIG. 2.
Before the video frames are provided to application 112, they are provided (as indicated by video frames 130 in FIG. 1) to video effect rendering component 120. An indication as to which video effects have been selected for rendering by the user is also provided to rendering component 120. This is indicated by block 164 in FIG. 2.
Video effect rendering component 120 then renders the selected video effects on frames 130 (such as by accessing effects data in data store 124) and returns frames 134, with the video effects rendered therein, to interface handler 118. This is indicated by block 166 in FIG. 2.
Having thus had the video effects rendered to the video frames, interface handler 118 then continues by passing the frames with the rendered effects down the filter graph. Interface handler 118 illustratively passes them to kernel streaming proxy 116 for further video processing, and on along to other filters in the filter graph generated by multimedia processing system 114. Passing the frames with the rendered effects down the filter graph is indicated by block 168 in FIG. 2.
It will be noted, of course, that interface handler 118 can add any desired additional information, other than the video effects, to frames 130, before passing them down the filter graph. For instance, interface handler 118 can add time stamp information, motion information, object tracking information (such as face tracking information indicating a location of a face within a frame), etc.
It can also be seen that because interface handler 118 has the video effects rendered as soon as the frames are received from kernel mode environment 102, the video effects will be present, in substantially real time, as if they originated at the camera driver, for all video enabled applications 112 that consume those frames. This is true, whether the consuming application is application 112 illustrated in FIG. 1, or a different application that consumes the frames at a different location.
FIG. 3 is a flow diagram better illustrating one embodiment in which multimedia processing system 114 generates a filter graph. A plurality of different filters can be generated, and the particular filters in the filter graph will vary based on the multimedia processing desired. For instance, in one embodiment, there may be a filter that sends video data across a wide area network, or to a monitor. By way of example only, a number of the filters associated with the present system are discussed in FIG. 3, and it will be appreciated that the filter graph is not to be limited by that discussion.
First, when multimedia processing system 114 begins to generate the filter graph, it creates a capture filter which, in the embodiment discussed herein is the kernel streaming proxy 116. This is indicated by block 180 in FIG. 3.
Kernel streaming proxy 116 then creates kernel streaming interface handler 118. This is indicated by block 182. In one illustrative embodiment, kernel streaming proxy 116 is a dynamic link library (DLL) and it creates interface handler 118 by referencing a globally unique identifier (GUID) in the system registry. Thus, in one embodiment, the GUID referenced by kernel streaming proxy 116 to create interface handler 118 is simply replaced such that proxy 116 creates the particular interface handler 118 that performs the video effect functions described herein.
In any case, once kernel streaming interface handler 118 is created, as indicated by block 182 in FIG. 3, kernel streaming interface handler 118 may optionally launch user selection component 122. This is indicated by optional block 184 in FIG. 3. This may be done, for example, where user selection component 122 is a separate application, separate from application 112. For instance, where user selection component 122 is a system tray application that is used by the user to select video effects for application to the video frames, that system tray application is launched by interface handler 118, once interface handler 118 is created by multimedia processing system 114. However, where user selection component 122 is part of consuming application 112, for instance, then its functionality is launched by consuming application 112, instead of interface handler 118.
