Description
Technical Field
The present application relates to the field of video playing, and in particular, to a method and a system for online playing of FLV format video.
Background
Currently, a mobile terminal broadcasts videos from internet multimedia more and more widely, and the commonly used videos have various formats. Video format refers to the manner in which video data, audio data, and related information data in a video are organized. Video data is realized according to a certain specific format in the processes of storage and transmission, and the different video formats are realized in different modes. The video formats commonly used at present mainly include FLV, HLS, and the like.
FLV is short for FLASH VIDEO, and the FLV streaming media format is a VIDEO format developed along with the introduction of FLASH MX. The video file can be watched on the network due to the fact that the file formed by the video file is extremely small and the loading speed is extremely high, and the video file can be effectively watched on the network.
FLV is adopted by many new generation video sharing websites, and is the fastest growing and most widespread video transmission format at present. Developed on the basis of the compression algorithm of sorenson corporation. The FLV format can be easily imported into Flash, has extremely high speed, can play a role in protecting copyright, and can play videos without local Microsoft or REAL players.
FLV, an emerging web video format, is supported by numerous websites and is not occasional. Besides the characteristics of low occupancy rate, good video quality, small volume and the like of the FLV video format, the FLV video format is suitable for network development, and rich and various resources are also an important factor for the uniform online playing of the FLV video format. From the latest transformers to jail-off and then to various sports programs, even self-timer videos made by net friends and the like can be easily found in the network.
There are two types of websites for providing FLV videos on the internet, one is a special video sharing website such as YouTube website in the united states, six rooms in the country, potato web, and the like. The other is that the portal provides a block of video podcasts, provides its own video channels, such as the Sino video podcasts, etc., and also uses FLV format video. In addition, the hundredth degree also promotes the function of video searching, and videos searched in the video searching basically adopt the popular FLV format.
HLS (HTTP Live Streaming) is mainly used for audio and video services of PC and Apple terminals. The media playback method comprises an m3u (8) index file, a TS media fragment file and a key encryption string file, wherein the index file is used for a player to perform seek operation on the TS media fragment file, and the TS media fragment file comprises played video data.
The commonly used streaming media protocols mainly include HTTP progressive download and real-time streaming media protocol based on RTSP/RTP, which are basically completely different things, and currently, the HTTP progressive download method is more convenient and better.
As a separate FLV file. While Flash video files are typically the control of the Flash Player being delivered, the FLV files themselves are fully functional to themselves and may be played out or converted to other formats, stored locally, such as on a hard disk or CD.
Video processing in the FLV format has the following benefits:
FLV is a brand-new streaming media video format, and integrates video into Flash animation by utilizing a Flash Player platform widely used on a webpage. That is to say, as long as the visitor of the website can watch the Flash animation, the visitor can naturally watch the FLV format video without additionally installing other video plug-ins, and the use of the FLV video brings great convenience to video transmission.
Based on the above advantages, it is popular to store the video file in the FLV format on the server, and distribute and play the video file after receiving the video playing request from the client. The client receives the video file sent by the server, then downloads the video information part with the FLV file header, and then downloads the actual FLV format video data for playing.
FLV, a popular video file format, can be played on multiple platforms. With the development of network technology, online playing of videos is more and more popular with people. However, since the FLV format video file contains information such as indexes of all audio and video frames in its header, the FLV format video file header is particularly large, and the buffering time at the beginning of the video is particularly long when playing the FLV format video file. If the FLV file is played online, that is, played at the bottom of the file, a long download buffer time of the video start file header is needed, and the download buffer time differs according to the difference of the total length of the video, which generally can reach 1M, and the experience of watching the FLV video file online by the user is seriously affected.
The current solution is to complete the conversion of FLV format video files by the server, by the following means:
(1) the video file format is converted into an FLV file format, and then the FLV file format is transmitted to a local player for playing, and the video playing starting fast buffer playing mode is carried out by utilizing the characteristic of small head of the FLV.
(2) The FLV format video file is divided into a plurality of FLV files of small segments of videos, so that the head of each small file is small, and the purpose of quick playing can be achieved.
(3) And converting the FLV format video file into a plurality of TS format video files, and playing the TS format video files by using an HLS technology.
If the format conversion process of the FLV format video is completely completed in the background server according to the above scheme, the following problems may be caused:
(1) in the prior art, the video file in the FLV format is converted into the video file in other formats on the server, but the converted video file is converted into a plurality of formats to adapt to different video playing platforms, so that the storage capacity of the service is greatly increased, and the cost of the server is increased.
(2) In the prior art, the video file in the FLV format is converted into the video files in other formats on the server, so that the same video stores the files in a plurality of formats on the server, and great troubles are brought to the file management of the server.
(3) In the prior art, the video file in the FLV format is converted into the video file in other format, that is, the fragmented video file, in the server, the data transmission of a plurality of small fragmented files may affect the transmission effect of the file, which is not beneficial to the playing of the client video.
(4) In the prior art, the video file in the FLV format is converted into the video file in other formats on the server, and the efficiency of network transmission performance between the streaming module and the format conversion module of the server is low, so that the problem that the client cannot smoothly receive the video file for playing is caused.
