The embeddable video capturing, processing, and conversion application 70 is subdivided into three major components, being an embedded application interface 71, a user interface 72, and a processing component 73. The embedded application interface 71 comprises an application programming interface as well as a visual interface which directly integrates into the program code or user interface of the external application 71. For instance, the embedded application interface 71 may be a button widget that becomes part of the external application's 31 user interface. Alternatively, the external application 31 may directly invoke an application programming interface of the embedded application interface 71. The user interface 72 is the collection of dedicated user interfaces (such as popup windows, screens, voice commands, etc.) which are used by the embeddable video capturing, processing and conversion application 70 to interact with the end user 12. For instance, the user interface 72 may comprise a file browser to present selectable input video files from a video source location 40, which may be a local file system. User interface 12 may further provide visual controls for providing feedback, such as showing status information about performing any of the video capturing, processing, and conversion activities. Finally, the processing component 73 may implement the core video capturing, processing, and conversion application logic, which may entail a video and audio file transcoding software, including video and audio codec libraries, a video analysis software and further signal processing and digital audio and video algorithms.
[0042] In one embodiment of the invention, the embeddable video capturing, processing and conversion application 70 may integrate with the external application 31 by replacing existing functionality or plugging into extension interfaces by means of late binding mechanisms. For example, an embeddable video capturing, processing and conversion application 70, which is a World Wide Web browser extension application may integrate with an external application, which is a client-side Web application written in JavaScript and HYPERTEXT MARKUP LANGUAGE (HTML) by replacing existing HTML markup for input controls that allow for uploading video files to the video target location 50 with invocations of the embeddable video capturing, processing, and conversion application 70 such that in effect, a simple video file upload to the video target location 70 is replaced by a more complex workflow involving some video processing steps such as video transcoding or video compression. In a variant of the aforementioned embodiment, the previous video source location 40, which may be the local file system of the client computing device 10 may be augmented with an additional video source location 40, which may be the camera and microphone of the client computing device 10. In another embodiment of the invention where the embeddable video capturing, processing, and conversion application 70 may be a software library such as a JAVASCRIPT library retrieved from an application outlet 60, which may be a directory of JAVASCRIPT libraries, the application publisher 32 of an external application 31, which may be a client-side Web application may use features of the embeddable video capturing, processing, and conversion application 70 to develop an external application 31 using these features. The embeddable video capturing, processing, and conversion application 70 may be a software application implemented in any programming language and using any application programming interfaces suitable to run in an application container 11. For instance, the embeddable video capturing, processing and conversion application 70 may be implemented using JAVASCRIPT, GOOGLE PORTABLE NATIVE CLIENT, ORACLE JAVA, ADOBE FLASH, MICROSOFT.NET, MICROSOFT SILVERLIGHT or other programming languages and application programming interfaces.
[0043] The client computing device 10 contains an application container 11, which is a software infrastructure to run applications such as the external application 31 and the embeddable video capturing, processing, and conversion application 70. The client computing device 10 may be operated by an end user 12, which may be a specific person, a logical user role, a group of people, or a technical component impersonating a person. Specifically, the end user uses and consumes the features provided by the aforementioned applications running in the application container 11.
[0044] The code location 20 may be communicatively coupled to the client computing device 10 and any software components therein, such as the application container 11. The code location 20 contains a replica of the embeddable video capturing, processing, and conversion application 70.
[0045] The application location 30 may be communicatively coupled to the client computing device 10 and any software components therein, such as the application container 11. The application location 30 contains the external application 31. The application publisher 32 is the person or organizational entity operating, owning, or legally controlling the external application 31 that is provided at the application location 30.
[0046] The video source location 40 and the video target location 50 are both communicatively coupled to the application container 11 and the applications running therein, like the external application 31 and the embeddable video capturing, processing, and conversion application 70. Both video source location 40 and video target location 50 may be part of the client computing device 10 or separate from the client computing device 10.
[0047] The end user 12 and the application publisher 32 may temporarily access the application outlet 50 through suitable user interfaces like search, browsing, listing interfaces and others, where an end user 12 or an application publisher 32 may retrieve a technical address such as a uniform resource locator (URL) of the embeddable video capturing, processing, and conversion application 70 at the code location 20. The end user 12 and the application publisher 32 may use the aforementioned technical address to retrieve a copy of the embeddable video capturing, processing, and conversion application 70 from the code location 20 for purposes such as installing the embeddable video capturing, processing, and conversion application 70 within the application container 11 or to integrate the embeddable video capturing, processing, and conversion application 70 with the external application 31.
[0048] The embeddable video capturing, processing, and conversion application 70 may contain three major components, being an embedded application interface 71, a user interface 72, and a processing component 73. The embedded application interface 71, the user interface 72, and the processing component 73 may be communicatively coupled using suitable communication infrastructure, including network communication protocols such as HYPERTEXT TRANSFER PROTOCOL (HTTP).
[0049] In an alternative embodiment of the invention, the embeddable video capturing, processing, and conversion application may partially or fully run on a computing infrastructure that is different from the local client computing device 10. That is, the application container 11 on the local client computing device 10 only runs a proxy component responsible for communicating with the actual runtime locations of the embeddable video capturing, processing, and conversion application 70. For example, the embeddable video capturing, processing, and conversion application may be running on a remote server, such as a Cloud-provisioned computer, that is communicatively coupled to the client computing device 10 through a suitable communication infrastructure such as the Internet. In an alternative variant of this embodiment, the embeddable video capturing, processing, and conversion application 70 may be running on another client computing device 10, which is different from the local client computing device. For example, a local client computing device 10, which is a World Wide Web browser may connect to another client computing device through suitable communication protocols such as WORLD WIDE WEB CONSORTIUM (W3C) WEBRTC where the other client computing device 10 runs the embeddable video capturing, processing, and conversion application 70 in its application container 11.
[0050] In another embodiment of the invention, the embeddable video capturing, processing, and conversion application 70 may be running on a distributed computing infrastructure where all of or portions of the embeddable video capturing, processing, and conversion application 70 are split into separate computing tasks that can run in isolation on different computing resources such as different central processing units (CPUs) or CPU cores of the client computing device 10, remote nodes of a communicatively coupled Grid computing infrastructure, a Hive computing infrastructure where a plurality of other client computing devices 10 each process a task that is a portion of the workload that is to be run by the embeddable video capturing, processing, and conversion application 70. For example, a workload representing a video transcoding job converting an input video file or stream from the video source location 40 into an output video file or stream (having a different format), which may be sent to the video target location, may be split into separate computing tasks where each computing task processes a separate sequence of the input video file or stream.
[0051] The invention proposed in this application implements an embeddable video capturing, processing, and conversion application 70, which may for instance comprise a video transcoding service, a video recording service, a video playback service, a video enhancement service, a video editing service, a video effects service or any other service suitable to capture video from a video source location 40 and process or convert a video in any way, producing an output video file or stream that is sent to a video target location 50. The embeddable video capturing, processing, and conversion application 70 may implement suitable video capturing, processing, and conversion algorithms such as video decoding and encoding algorithms, signal processing algorithms, image processing algorithms and procedures to interface video source locations 40 (such as file systems, databases, remote server computers, World Wide Web services, cameras and microphones, computer screen recording interfaces, etc.) where an input video file or stream is received and procedures to interface video target locations 50 (such as file systems, databases, remote server computers, World Wide Web services, video playback devices and software, etc.) that an output video file or stream (which is produced by the embeddable video capturing, processing, and conversion application 70) is sent to. The embeddable video capturing, processing, and conversion application 70 may be implemented in a programming language and using application programming interfaces suitable to run in an application container 11 (such as a World Wide Web browser (such as GOOGLE CHROME, APPLE SAFARI, MICROSOFT INTERNET EXPLORER, MOZILLA FIREFOX and others), a mobile device operating system such as APPLE IOS, GOOGLE ANDROID, MICROSOFT WINDOWS PHONE, etc.) on a client computing device 10. For example, when the application container 11 is a World Wide Web browser, the embeddable video capturing, processing, and conversion application 70 may be implemented in JAVASCRIPT, HYPERTEXT MARKUP LANGUAGE (HTML) and CASCADING STYLE SHEETS (CSS). In another example where the application container 11 is an APPLE IOS operating system for mobile devices, the embeddable video capturing, processing, and conversion application 70 may be implemented in the OBJECTIVE-C programming language, using the APPLE COCOA TOUCH application programming interfaces. Other examples of common programming languages targeting specific application containers 11 are GOOGLE PORTABLE NATIVE CLIENT (PNaCl) for the GOOGLE CHROME World Wide Web browser, MICROSOFT SILVERLIGHT for the MICROSOFT INTERNET EXPLORER World Wide Web browser, ADOBE ACTIONSCRIPT for ADOBE FLASH plugins of World Wide Web browsers, ORACLE JAVA for GOOGLE ANDROID-based mobile devices, KHRONOS GROUP WEBGL for WEBGL-enabled World Wide Web browsers and other programming languages suitable to implement an embeddable video capturing, processing, and conversion application 70. All of or portions of the embeddable video capturing, processing, and conversion application 70 may be cross-compiled from existing, third-party source code into the aforementioned programming languages. For example, the open source FFMPEG, LIBAV, MPLAYER, VIDEOLAN X264, INTEL OPENCV software libraries may be cross-compiled to build the embeddable video capturing, processing, and conversion application 70. The embeddable video capturing, processing, and conversion application 70 comprises of three major components, being an embedded application interface 71, a user interface 72, and a processing component 73. The embedded application interface 71 may be the software integration layer to the external application 31, using common techniques for integrating different software components (such as offering an application programming interface of callable services and application events that can be subscribed to or code injection technique where the external application 31 is dynamically modified at runtime to invoke services of the embeddable video capturing, processing, and conversion application 70) to provide callable services interfaces to the external application 31 and optionally inserting user interface components such as buttons, voice commands, touch and mouse gestures, keyboard commands, etc. into the user interface of the external application 31. The external application 31 may pass control over to the embeddable video capturing, processing, and conversion application 70 by invoking services of the embedded application interface 71. The user interface 72 provides a suitable user interface to engage the end user 12 in performing video capturing, processing, and conversion services. The user interface may use any suitable technique to interact with the end user 12 such as visual user interface controls (such as buttons, input boxes, etc.), voice output and input commands, touch and mouse gestures, etc. Example services provided by the user interface 72 are displaying progress and status information while the processing component 73 performs a video capturing, processing or conversion job, capturing user-defined parameters to control a video capturing, processing, or conversion job, implementing additional video source locations 40 such as a video recorder accessing cameras or microphones of the client computing device 10, implementing additional video target locations 50 such as a software-based video player, etc. The processing component 73 implements the core video processing and conversion services, such as video transcoding, signal processing, image processing, etc.
[0052] The invention further provides for mechanisms to embed and integrate the aforementioned embeddable video capturing, processing, and conversion application 70 into an external application 31, such as a World Wide Web application, an application running on mobile devices or any other software application running on client computing devices, such as personal computers, workstations, laptops, notebooks, smartphones, tablet computers, smart watches, etc. In one embodiment of the invention these integration mechanisms comprise of providing an application programming interface to external applications 31. An application publisher 32, who is the person, organizational entity, or a person or organization affiliated with the application publisher 32 may implement or modify the external application 31 code to integrate to the embeddable video capturing, processing, and conversion application 70 using suitable application integration techniques, such as message passing, service invocation, event subscription, class inheritance, configuration, etc. As a result, the external application 31 may be readily integrated with the embeddable video capturing, processing, and conversion application 70 when it is received at the application container 11 from the application location 30.
[0053] The general procedure of running an external application 31 inside an application container 11 is shown in FIG. 3, which shows a flow chart 300. The procedure may be started from arbitrary external stimuli, such as the end user 12 of the client computing device 10 requesting the external application 31 to be loaded or an automatic mechanism (such as a time-scheduled action, or a request received from an external component) doing so. In step 305, the application container 11 loads the external application 31 from the application location 30. For example, when the application container 11 is a World Wide Web browser and the application location 30 is a World Wide Web server, step 305 corresponds to the application container 11 performing a HYPERTEXT TRANSFER PROTOCOL (HTTP) "GET" request against a UNIFORM RESOURCE LOCATOR (URL) of a World Wide Web server, representing application location 30. When the external application 31, which may be a number of JAVASCRIPT, HYPERTEXT MARKUP LANGUAGE (HTML), CASCADING STYLE SHEET (CSS), etc. resources, was received by the application container 11, it may be parsed and interpreted, thus running the external application 31. In another example, when the application container 11 is an operating system such as APPLE IOS, step 305 corresponds to loading and instantiating a software application that is installed on the client computing device 10 representing the external application 31 from the local device's storage device into main memory and invoking a software routine suitable to launch the application. In step 310, the application container 11 loads and instantiates the embeddable video capturing, processing, and conversion application 70 from the code location 20. Loading and instantiating the embeddable video capturing, processing and conversion application 70 may be triggered by instantiating the external application 31 (step 305), which may include references to the embeddable video capturing, processing, and conversion application 70. For instance, an external application 31, which is a client-side World Wide Web application, may contain suitable commands to retrieve and instantiate the resources that make up the embeddable video capturing, processing, and conversion application 70, such as HYPERTEXT MARKUP LANGUAGE elements that request JAVSSCRIPT files from a World Wide Web server, which may represent code location 20. In step 315, the external application 31 configures the embeddable video capturing, processing, and conversion application 70, such as to determine the appearance and behavior of any user interface components that are part of the embedded application interface 71 or the user interface 72, to select a subset of services to be subsequently consumed, or to parameterize the embeddable video capturing, processing, and conversion application 70 in any other way that may be supported by its application programming interface. Sometime during the course of running the external application 31 and its embedded video capturing, processing, and conversion application 70 and after step 315 was completed, either step 320 or step 325 may be performed. In step 320, the end user 12 may trigger the application interface 71 by interacting with the contained user interface such as clicking or tapping on a button. Alternatively, in step 325 the external application 31 programmatically triggers the application interface 71, such as by invoking a service interface that is part of the application programming interface exposed by the application interface 71. As a result of both step 320 and step 325, in step 330, an input video file or stream may be received from a video source location 40. For instance, in step 320 the end user 12 may have clicked on a button that is part of the embedded application interface 71. As a result a file selection window may have allowed the user to pick an input video file from the local storage device of the client computing device 10. In another embodiment of step 320, a video recording user interface, which may be connected to a camera or microphone of the client computing device 10 may be opened where the end user 12 may record a video or audio file from the aforementioned cameras or microphones. In another example, in step 325 the external application 31 may programmatically invoke the embedded application interface providing an input video file or stream, which was previously received by the external application 31 such as from a remote server like a World Wide Web server. In step 335, the user interface 72 of the embeddable video capturing, processing, and conversion application 70 may (optionally) capture additional parameters for the subsequent invocation of the processing component 73 from the end user 12. For instance, the user interface 72 may be a slider bar, where the end user 12 can control the compression ratio of a video conversion job that is performed by the processing component 73. In another example, other video conversion and processing parameters such as the format of the output video file or stream may be captured using suitable user interface elements, such as graphical widgets for mouse or touch interaction, voice commands, textual input, etc. Finally, in step 340 the processing component 73 of the embeddable video capturing, processing, and conversion application 70 may perform a video capturing, processing, or conversion job, such as video transcoding, video compression, video editing, video enhancement, automatic generation of a video digest, which is a short summary of one or a plurality of input videos. Step 340 consumes the input video file or stream received in step 330, and may use both the default configuration provided by the external application 31 in step 315 and the end user 12 parameters captured in step 335. In step 340, the processing component 73 may produce an output video file or stream that is sent to the video target location 50. The output video file or stream may be produced progressively where only successive portions of the output video file or stream are sent to the video target location 50 or in a single step where the entire output video file or stream is sent to the video target location 50. In one embodiment of the invention, the video target location 50 may be the external application 31 or another run of the embeddable video capturing, processing, and conversion application 70 (or invocations of sub-components or sub-processes of these two applications).
[0054] FIG. 2 depicts a flow chart 200, which is an alternative embodiment of the invention where the end user 12 may install the embeddable video capturing, processing, and conversion application 70 into the application container 11 on the client computing device 10. In step 210, the end user 12 accesses the application outlet 60, which may be a digital marketplace or directory of applications suitable to run in the context of an application container 11. For instance, the embeddable video capturing, processing, and conversion application 70 may be a World Wide Web browser extension or plugin, which is listed on application outlets 60, such as the GOOGLE CHROME WEB STORE, the MOZILLA MARKETPLACE, the APPLE SAFARI extensions directory and others. In the context of this example, the application container 11 may be a World Wide Web browser suitable to be functionally extended by suitable applications, such as the embeddable video capturing, processing, and conversion application 70. In step 220, the end user 12 triggers a service of the application container 11, causing it to download a copy of the embeddable video capturing, processing, and conversion application 70 from the application outlet 60. For example, when the application container 11 is a World Wide Web browser, step 220 may correspond to installing a World Wide Web browser extension from a directory of extensions, such as the aforementioned vendor-specific application outlets 60. In another example where the application container 11 may be an operating system of the client computing device 10, such as an operating system running on smartphones, tablets, or other devices, step 220 may correspond to installing an application from an application outlet, which is an application store, such as the GOOGLE PLAY STORE for client computing devices 10 running the GOOGLE ANDROID operating system, the APPLE APP STORE for client computing devices 10 running the APPLE IOS operating system or any other application store providing applications, such as the embeddable video capturing, processing, and conversion application 70 for application containers 11 being operating systems of client computing devices 10. In step 230, the end user 12 triggers the application container 11 to load an external application 31, such as a World Wide Web application, from an application location 30, such as a World Wide Web server. For instance, when application container 11 is a World Wide Web browser such as GOOGLE CHROME, APPLE SAFARI, MOZILLA FIREFOX, MICROSOFT INTERNET EXPLORER, etc., loading an external application 31 may correspond to the application container 11 requesting resources such as JAVASCRIPT, HYPERTEXT MARKUP LANGUAGE (HTML), CASCADING STYLE SHEET (CSS) and other files from an application location 30, which may be a World Wide Web server, serving files over a network such as the Internet using computer network protocols such as HYPERTEXT TRANSFER PROTOCOL (HTTP) and others. In step 240, the application container 11 instantiates and starts the external application 31. For example, when the application container 11 is a World Wide Web browser and the external application 31 is the aforementioned collection of resources retrieved from an application location 30, which may be a World Wide Web server, instantiating the external application 31 may correspond to parsing and interpreting script and markup resources such as JAVASCRIPT, HYPERTEXT MARKUP LANGUAGE, CASCADING STYLE SHEET files and others. In steps 250 and 260, the embeddable video capturing, processing, and conversion application 70, which was installed in step 220, may be triggered in the context of the external application 31 that was loaded and instantiated in steps 230 and 240. That is, the embeddable video capturing, processing, and conversion application 70 may identify all interfaces of the external application 31 to video source locations 40 (step 250) and video target locations 50 (step 260). For example, when the application container 11 is a World Wide Web browser and the external application 31 is a client-side World Wide Web application out of HYPERTEXT MARKUP LANGUAGE, JAVASCRIPT, and other files, identifying interfaces to video source locations 40 and video target locations 50 may be performed by a combination of suitable parsing, scanning and other reverse engineering techniques. For example, interfaces to video source locations 40 may be file input elements present in the HYPERTEXT MARKUP LANGUAGE files, invocations to application programming interfaces of the application container 11 for retrieving or downloading input video files or streams from a video source location 40, which may be a remote World Wide Web server (such as the WORLD WIDE WEB CONSORTIUM XMLHTTPREQUEST, FILE, WEBSOCKET and other APIs). In turn, interfaces to video target locations 50 may for instance be HYPERTEXT MARKUP LANGUAGE elements for video playback inside the application container 11, JAVASCRIPT invocations of application programming model interfaces to store and upload data such as output video files or streams, etc. After identifying the existing interfaces of the external application 31 to video source locations 40 and video target locations 50, step 260 modifies and augments these interfaces with invocations of the embedded application interface 71. Specifically, the embedded application interface 71 may be invoked after the external application 31 receives an input video file or stream from a video source location 40 and before the external application 31 stores an output video file or stream to a video target location 50. Injecting the embeddable video capturing, processing, and conversion application 70 may be performed by dynamic code injection and interpretation techniques such as script injection and event coupling, where the embeddable video capturing, processing, and conversion application 70 code is triggered in response to an event being raised by the external application 31, in-place code modification where the code of the external application 31 is overwritten and changed in place, letting it perform invocations of the embedded application interface 71 of the embeddable video capturing, processing, and conversion application 70, late binding techniques where bindings to service invocations are set or updated at runtime. Application containers 11 being World Wide Web browsers often provide dedicated application programming interfaces for extensions such as the embeddable video capturing, processing, and conversion application 70, where the external application 31 that is presently run by the application container 11 can be inspected and influenced.
