Embodiment Construction

[0055] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0056] One of the core concepts of the embodiments of the present application is to divide the original video code stream and encapsulate it according to the format of the video file to be generated, so as to synchronously generate video files of multiple formats, thereby greatly improving the generation efficiency of multi-format video files.

[0057] figure 2 The implementation flow of the video file generation method provided by the embodiment of the present application is shown, and the details are as follows:

[0058] In step S201, the original video code stream is obtained;

[0059] In the embodiment of the present application, the original video code stream is an H.264 code stream.

[0060] As ...

Abstract

The application provides a video file generation method and a system. The method comprises acquiring an original video code stream; partitioning the original video code stream into original video frames, which have corresponding timestamps respectively; and packing up the original video frames and the corresponding timestamps to a to-be-generated video format file. According to the application, various formats of video files can be generated so as to obviate unnecessary coding and decoding, thereby lowering CPU (central processing unit) loss and greatly improving the generation efficiency of multi-format videos.

Description

technical field [0001] The present application belongs to the technical field of multimedia data processing, in particular to a video file generation method and system. Background technique [0002] Such as figure 1 As shown, the process of generating a video file in a certain format in the prior art is: [0003] In step S101, the original video encoder writes the video stream into the H.264 original video code stream file; [0004] In step S102, the encoder of a certain video file format reads the H.264 original video code stream file, and writes the video data into the video file of the format; [0005] In step S103, the decoder of the video file format to be generated reads the above-mentioned video file, and writes the read video data into the memory; [0006] In step S104, the encoder of the video file format to be generated reads video data from the internal memory, and writes it into the video file of the format to be generated. [0007] It can be seen from the ab...
