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
The application relates to video playback field, specifically, relates to the method and system that a kind of MP4 format video is play online.
Background technology
At present, mobile terminal order video from internet multimedia is more and more extensive, and conventional video has various different form.Video format just refers to the mode video data in video, voice data and relevant information data organized.Video data all realizes according to certain specific form in storage and transmitting procedure, and different video format implementations is not identical yet.The video format that present stage is commonly used mainly contains FLV, MP4 and HLS etc.
MP4, full name MPEG-4Part14, be a kind of multimedia computer File Format using MPEG-4, secondary shelves are called MP4, to store digital message and digital video signal.MP4 is a set of compression and coding standard for audio frequency, video information, formulated by " dynamic image expert group " (MovingPictureExpertsGroup, i.e. MPEG) of International Organization for standardization (ISO) and International Electrotechnical Commission (IEC) subordinate.
MP4 file format is an open video format, almost can be used for describing all media structures, media description in MP4 file and media data are what to separate, and organizing of media data is also very free, do not need according to time sequencing arrangement, even media data directly can quote alternative document.Meanwhile, MP4 also supports Streaming Media, and MP4 is widely used in encapsulating h.264 video and AAC audio frequency at present, is the representative of HD video.
General MP4 file the most important thing is two parts, one is the video information part with MP4 file header, what preserve inside this is Video Key information, comprise the information such as the coded format of audio frequency and video in video file, the resolution of video, the sample rate of audio/video, sampling precision, channel number, the size information of each audio/video bag and the timestamp corresponding to each audio/video bag, another part is actual MP4 format video data.The player of mobile terminal, when playing MP4 format video, first can ask the video information part with MP4 file header.
HLS (HTTPLiveStreaming), is mainly used in the audio frequency and video service of PC and Apple terminal.Comprise the index file of a m3u (8), TS media slicing file and key encrypt string file, and index file is used for player and carries out seek operation to TS media slicing file, and TS media slicing file includes the video data of broadcasting.
Conventional stream media protocol mainly contains HTTP progressive download and the real-time stream media protocol based on RTSP/RTP, and these two kinds is diverse thing substantially, at present more convenient handy be again by HTTP progressive download method.
The Video processing of MP4 form is adopted to have following benefit:
(1) different encryption algorithms can be adopted for different audio/video object, thus improve the compression efficiency of audio/video;
(2) relatively independent separately between audio/video object, improve the reusability of multi-medium data;
(3) allow user to operate single audio/video object, facilitate the interactive experience of user;
(4) flexible allocation code check between different audio/video object is allowed, can realize according to significance level distribution byte how many: more byte can be distributed to important object, less byte can be distributed to secondary object, thus good effect can be obtained under low bit-rate.
(5) can integrated naturetone/object video and synthesized voice object video easily.
Based on above-mentioned benefit, the video file of current trend store M P4 form on the server, carries out distribution again and plays after receiving the video playback request of client.First download the video information part with MP4 file header after the video file that client reception server sends, download actual MP4 format video data afterwards again and play.
MP4, as a kind of popular video file format, can play on multiple platforms.Along with the development of network technology, online displaying video is more and more popular to people.But, to contain the information such as the index of its all audio frequency and video frame due to the video file of MP4 form at its head, make the video file head of MP4 form large especially, when carrying out MP4 format video file and playing, long especially in the buffer time that video is initial.If play online MP4 file, namely limit is play below, can cause the download buffer time of the video start file head needing to grow very much, and variant according to the difference of video footage, generally can reach 1M, have a strong impact on the experience that user sees online viewing MP4 video file.
Current settling mode is the conversion being completed MP4 format video file by server, in the following manner:
(1) be converted into FLV file format, then be transferred to local player plays, utilize the mode that the feature that FLV head is less is play to carry out the initial fast cache of video playback.
(2) MP4 format video file division be multiple MP4 files of segment video, so, the head of each small documents is very little, also can reach the object play fast.
(3) MP4 format video file transform is become the video file of multiple TS form, utilize HLS technology to carry out the broadcasting of TS format video file.
If according to such scheme, the format conversion process of MP4 format video all completes at background server, can bring following problem:
(1) prior art realizes the video file video file of MP4 form being converted to other form on the server, but the video file after conversion must be transformed to multiple format to adapt to different video playback platforms, so, considerably increase the memory space of service, add the cost of server.
(2) prior art realizes the video file video file of MP4 form being converted to other form on the server, causes same video to store the file of multiple form on the server, brings very burden to the file management of server.
(3) prior art realizes the video file video file of MP4 form being converted to other form on the server, the i.e. video file of burst, the transfer of data of multiple little slicing files can have influence on the laser propagation effect of file, is unfavorable for the broadcasting of client video.
(4) prior art realizes the video file video file of MP4 form being converted to other form on the server, network transmission performance efficiency between the fluidisation module of server and format converting module is low, thus slack problem when causing client receiver, video file to be play.
Summary of the invention
In order to solve produced problem in the above prior art, the object of this invention is to provide the method and system that a kind of MP4 format video is play online.
The invention provides a kind of method that MP4 format video is play online, comprising:
