Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise, and "a plurality" typically includes at least two.
The words "if", as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.
In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.
Fig. 1 is a flowchart of a video cover setting method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
101. and obtaining an open source computer program FFmpeg, and compiling the FFmpeg to obtain a WebAssembly library.
102. And acquiring target video data uploaded by a user.
103. And calling a video decoding function interface in the compiled FFmpeg through the high-level programming language JS to decode the target video data.
104. And acquiring a target video frame in the decoded video data.
105. The target video frame is set as a cover description image of the target video data.
The FFmpeg is a set of open source computer programs that can be used to record, convert digital audio, video and convert digital audio, video into streams. It provides a complete solution for recording, converting and streaming audio and video. The method comprises a very advanced audio/video coding and decoding library libavcodec, and in order to ensure high portability and coding and decoding quality, a lot of codes in the libavcodec are developed from a zero base. FFmpeg was developed under the Linux platform, but it can also be compiled to run in other operating system environments as well, which may include Windows, Mac OS X, etc.
The WebAssembly library is a brand new format which is portable, small in size, fast to load and compatible with Web. The WebAssembly library can be the compiled target of any programming language, so that the application program can run in a browser or other agent. The WebAssembly library can be called by JavaScript to enter a JavaScript context, and can also call the functions of a browser like WebAPI.
It is understood that FFmpeg cannot run in a browser, but FFmpeg provides many video codec functions that can decode many video data. After the FFmpeg is compiled, the FFmpeg is converted into a WebAssembly library which can run in a browser, so that the compiled FFmpeg can run in the browser and can also provide video coding and decoding capabilities in the browser.
People can register own individual account in a video website and then upload some video data in the individual account to be provided for vast net friends to watch. In order to describe the main content of the target video data conveniently, after the target video data is uploaded, the browser can extract a certain video frame in the target video data as a cover page description image of the target video data, and the cover page description image is displayed in a video playlist of the personal account.
After the browser receives target video data uploaded by a user, a video decoding function interface in the FFmpeg after compiling can be called through JavaScript, and the target video data is decoded through the video decoding function interface.
It is understood that the entire target video data may be decoded, so that all video frames can be decoded, and in order to save the amount of computation, optionally, the target video frame in the target video data may also be decoded by using the video decoding function interface in the FFmpeg after the JS call is compiled. Because only the target video frame is needed to be used when the cover description image is set, only the target video frame in the target video data can be decoded.
Two ways of obtaining a target video frame are described below.
Alternatively, the process of acquiring the target video frame in the decoded video data may be implemented as: and determining the first video frame in the decoded video data as a target video frame.
In practical applications, the first video frame in the decoded video data may be used as the target video frame.
Alternatively, the process of acquiring the target video frame in the decoded video data may be implemented as: displaying a video playing time axis corresponding to the decoded video data; detecting a target time point selected by a user on a video playing time axis; determining a preview image corresponding to a target time point in the decoded video data; displaying the preview image; and if the selection operation of the user on the preview image is detected, determining the preview image as the target video frame.
In practical applications, it is assumed that the decoded video data is a video clip with a playing time of 60 minutes, and a video playing time axis corresponding to the video clip with the playing time of 60 minutes can be generated. A draggable control can be arranged on the video playing time axis, and a user can drag the control to select a target time point. After detecting a target time point selected by a user on a video playing time axis, a preview image corresponding to the target time point in the decoded video data can be determined. For example, if the user selects a 35 minute 28 second preview image of the preview video segment by dragging the control, the 35 minute 28 second preview image can be captured and then presented. It is to be understood that if the user is satisfied with the preview image, and the preview image is considered to be in accordance with the core theme of the target video data, the preview image may be determined to be set as the target video frame by a selection operation on the preview image.
By adopting the method and the device, the FFmpeg is compiled into the WebAssembly library, so that the compiled FFmpeg can run in a browser and can provide video coding and decoding capabilities in the browser, and the browser can successfully decode video data with different formats by calling a video decoding function interface in the compiled FFmpeg through JS. And then, a cover description image can be extracted through the decoded video data, so that the cover description image of the video data can be normally set.
