Method and system for online playback of mp4 format video

Abstract

The invention discloses an online playing method for MP4-format video. The method comprises the steps that a client end receives MP4-format video data and corresponding description file information which are returned after an MP4-format video file online playing request is sent to a server, wherein the description file information comprises information required for converting an MP4-format video file into TS fragments; according to the description file information, the client end generates corresponding TS index files and sends the TS index files to a player of the client end, and a TS index file list is generated on the player; the player sends a TS fragment playing request to the client end according to the sequence of the TS index file list; the client end obtains corresponding MP4-format video data according to the TS fragment playing request, converts the MP4-format video data into the TS fragments and returns the TS fragments to the player; the player receives the TS fragments and plays the TS fragments in sequence. By means of the online playing method and system for the MP4-format video, the initial buffering time of online playing of the MP4-format video file is greatly shortened.

Description

technical field [0001] The present application relates to the field of video playing, and in particular, relates to a method and system for online playing of MP4 format video. Background technique [0002] At present, it is more and more common for mobile terminals to order videos from Internet multimedia, and commonly used videos have various formats. The video format refers to the way of organizing the video data, audio data and related information data in the video. Video data is implemented in a specific format during storage and transmission, and different video formats are implemented in different ways. The commonly used video formats at this stage mainly include FLV, MP4 and HLS. [0003] MP4, full name MPEG-4 Part 14, is a multimedia computer file format using MPEG-4, with the sub-file named MP4, mainly for storing digital audio and digital video. MP4 is a set of compression coding standards for audio and video information, formulated by the Moving Picture Experts...

AI Technical Summary

Problems solved by technology

[0021] (1) prior art scheme realizes that the video file of MP4 format is converted into the video file of other formats on server, but the video file after conversion must also be transformed into multiple formats to adapt to different video playback platforms, so, greatly Increase the storage capacity of the service and increase the cost of the server

[0022] (2) prior art scheme realizes that the video file of MP4 format is converted into the video file of other formats on the server, causes same video to store the file of a plurality of formats on the server, brings very big trouble to the file management of server

[0023] (3) prior art scheme realizes that the video file of MP4 form is converted into the video file of other formats on server, promptly the video file of fragmentation, the data transmission of a plurality of small fragmentation files can affect the transmission effect of file, can not Facilitate the playback of client video

[0024] (4) The existing technical scheme realizes that the video file of MP4 format is converted into the video file of other formats on the server, and the network transmission performance efficiency between the streaming module of the server and the format conversion module is low, thereby causing the client to receive the video file Unsmooth problem when playing
