Problems solved by technology

[0019] (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
[0020] (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
[0021] (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
[0022] (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

[0068] The file header of the usual MP4 format video file is relatively large, which not only contains the key information of the video, but also includes the encoding format of the audio and video in the video file, the resolution of the video, the sampling rate of the audio / video, the sampling accuracy, the number of channels, Information such as the size information of each audio / video packet and the time stamp corresponding to eac...

Embodiment 2

[0077] Such as figure 2 Shown, on the basis of embodiment 1, the method for a kind of MP4 format video online playback of this present invention comprises:

[0078] Step 201, the client receives the requested MP4 format video data and its corresponding description file information returned after sending the MP4 format video file online playback request to the server, wherein,

[0079] Described description file information comprises: described MP4 format video file is converted into the required information of target format video file;

[0080] The preservation process of the MP4 format video file on the server is as follows:

[0081] After the server receives the MP4 format video source file, the file header of the MP4 format video source file is dispersed into respective file header fragments according to the key frame of the MP4 format video source file, and is stored in the MP4 format video The respective corresponding positions in the source file;

[0082] Generate co...

Embodiment 3

[0090] Such as image 3 Shown, be a kind of MP4 format video online broadcasting method of the present invention a specific embodiment, comprise:

[0091] Step 301, the client receives the requested MP4 format video data and its corresponding description file information returned after sending the MP4 format video file online playback request to the server, wherein,

[0092] The description file information includes: information required for converting the MP4 format video file into an FLV format video file.

[0093] Step 302, the client generates a file header of the video in FLV format according to the description file information and sends it to the player of the client.

[0094] Wherein, the information of the number and size of all frames before each key frame is carried in the fragment of the MP4 file header, and the key frame index is added in the FLV file generated for convenience.

[0095]Step 303, the client converts the MP4 format video data into FLV format video ...

Abstract

The invention discloses a MP4 format video online play method. The method comprises the following steps that a client receives requested MP4 format video data and corresponding description file information which are returned after a MP4 format video file online play request is sent to a server, wherein the description file information includes information needed for converting a MP4 format video file into a target format video file; the client generates a file header of a target format video according to the description file information and sends to a player of the client; the client converts the MP4 format video data into target format video data and sends to the player; and when playing the video, the player takes the target format video data generated after format conversion to play according to the file header of the target format video. By using the method, first buffer time of MP4 format video file online play 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, HLS and TS. [0003] MP4, the full name of 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 Pict...
