Problems solved by technology

Just relying on a picture alone cannot allow users to understand the main content of the video, and if users watch a certain video normally, if they want to understand the plot development of the video, they need to view it in the way of fast forwarding or jumping, while fast forwarding Or jump to watch after waiting for the video to buffer

[0046] See figure 1 , which is a flow chart of the first embodiment of a method for generating a dynamic thumbnail provided in an embodiment of the present invention; the method may include the following steps:

[0047] S101. Extract multiple image frames of a first video file.

[0048]In the embodiment of the present invention, the video file is a video file in formats such as AVI, wma, MP4, and flash generated by compressing multiple image frames. Since the existing video file is relatively large, the terminal does not need to extract the video before generating a dynamic thumbnail. All image frames of the file, so the first step of the method for generating dynamic thumbnails first extracts a plurality of image frames for generating dynamic thumbnails of the first video file, wherein "multiple" means two or more , the above-mentioned dynamic thumbnail represents a GIF image or video file that can be dynamically played after being compressed, which is convenient for users t...

[0054] See figure 2 , which is a flow chart of the second embodiment of a method for generating a dynamic thumbnail provided by an embodiment of the present invention; the method may include the following steps:

[0055] S201. Parse the first video file to obtain basic information of the first video file.

[0056] In the embodiment of the present invention, the terminal parses the above-mentioned first video file to obtain the basic information of the above-mentioned first video file, wherein the above-mentioned basic information includes but not limited to: the duration of the video file, audio stream, video stream, mime type, code The rate type, the encoding method of the video stream, and the end mark of the video file, etc. Since the generated dynamic thumbnail is a compressed video as long as the video has no audio, parsing the basic information of the video file does not require parsing some features of the audio stream. For example, taking an MP4 file as an example, ...

[0068] See image 3 , which is a flow chart of the third embodiment of a method for generating a dynamic thumbnail provided by an embodiment of the present invention; the method may include the following steps:

[0069] S301. Parse the first video file to obtain basic information of the first video file.

[0070] In the embodiment of the present invention, the terminal parses the above-mentioned first video file to obtain the basic information of the above-mentioned first video file, wherein the above-mentioned basic information includes but not limited to: the duration of the video file, audio stream, video stream, mime type, code The rate type, the encoding method of the video stream, and the end mark of the video file, etc. Since the generated dynamic thumbnail is a compressed video as long as the video has no audio, parsing the basic information of the video file does not require parsing some features of the audio stream.

Abstract

The embodiment of the invention relates the technical field of electronics, and discloses a method for generating a dynamic thumbnail. The method comprises the following steps: extracting a plurality of image frames of a first video file; adding the plurality of extracted image frames into a thumbnail image set; and generating the dynamic thumbnail according to the image frames in the thumbnail image set. The embodiment of the invention further provides a terminal. Through adoption of the embodiment of the invention, quick preview of video files can be realized; a user can get the main information of the video files in a short time; and the user experience is improved.

Description

technical field [0001] The invention relates to the field of video information, in particular to a method and terminal for generating dynamic thumbnails. Background technique [0002] The video resources are displayed to the user by the video service provider through a page, and the user can order the corresponding video on the corresponding page. At present, the preview interface usually adopts static pictures, and these pictures are generally the first frame of the video or screenshots of the video album. Just relying on a picture alone cannot allow users to understand the main content of the video, and if users watch a video normally, if they want to understand the plot development of the video, they need to view it in a fast-forward or jump way, and fast-forward Or jumping needs to wait for the video to buffer before watching it. [0003] In the prior art, for users, if the current network condition is not good, fast forwarding or jumping will take too long to wait for...
