91flv video Playback system
     with the rise of video sharing sites, as well as the popularity of smartphones, a large number of offline video transcoding needs to be done to accommodate heterogeneous networks and multi-terminal environments, 2009 started the development of the video transcoding platform (converting various formats of video files into H264 encoded mp4,3gp files), And in June 2010 launched the 2.0 version, April 2011 successfully launched the 2.5.1 version, after the introduction of continuous absorption of user opinion, continuous improvement, updated to the current 2.5.3 version. At the same time, we combine the MapReduce distributed computing idea of cloud computing, and construct a cloud transcoding platform with multiple machines to achieve ultra-fast and even quasi-real-time transcoding.
      91flv Video transcoding server can convert various formats of AV files to the standard MP4 file (video using H. Encode, audio using AAC encoding), transcoding process from the transcoding server scheduling multiple transcoding servers to complete the batch transcoding work, transcoding server using multi-core, multi-threaded , multi-tasking format conversion processing, and according to actual use requirements, the use of file segmentation transcoding mode to complete the minimum time for users to complete transcoding requirements, transcoding server using hardware Cuda technology to speed up the transcoding process, fast completion of transcoding work, for high-end application needs, transcoding servers can be equipped with GPU high-speed processing technology, and work together with CPUs to achieve more efficient transcoding. High-speed transcoding server through transcoding task processing software, convenient for users to complete the batch transcoding work, and Rest mode based on a series of Web API interface, easy integration with third-party application systems.
through the actual large-scale application testing, for 1080P HD programs, the use of our high-profile transcoding server can achieve 32 times times faster transcoding efficiency, if more than one server at the same time can be transcoding speed to achieve a linear large-scale increase.

2. Cloud transcoding service mode
     transcoding Work mode: Users through a variety of terminal equipment through the Web server will need to transcode files to the Jobtracker server, while the completion of the file partition work assigned to the transcoding server for transcoding work, After the transcoding is completed, the MP4 file is uploaded to the Reducetask server to complete the merge work of the file and submitted to the Web server for user's use.
3. Features of the cloud transcoding platform
1. Wide range of equipment support
     support a variety of input devices, including hard disk,CD (including DTS), VCD, DVD, etc.
support A variety of mainstream AV formats, including MPEG1/2/4,RM/RMVB, WMV, MOV, MTS, etc., support various output parameter settings, the system built-in mainstream device output parameter template, including PC, Android phone, iphone, IPod, IPad, AppleTV, PSP, PS3, and more.
2. transcoding function supports comprehensive
     supports multi-track technology, which preserves all audio tracks of the source file. Support subtitle transcoding, including embedded subtitles and external subtitles in source files.  
Support anti-interleaving processing, automatically anti-interleaving source video, improve video clarity.  
3. Excellent transcoding speed
     Support Hardware codec acceleration: Using cuda Parallel computing technology, greatly improve transcoding performance. Dozens of times times higher than the traditional transcoding method.
Intelligent detection of machine hardware performance, according to the policy to start multiple transcoding processes, each process starts multiple transcoding threads simultaneously transcoding, take full advantage of multi-core, multi-process, multi-threading advantages to improve transcoding performance.  
support for segmented transcoding: A file can be precisely divided into multiple segments using multi-core simultaneous transcoding, quickly merged into the entire file.
4, powerful page upload function
support for the continuation of the breakpoint, seconds, drag-and-drop upload, batch upload.
upload unlimited video files without needing to configure the server and install plugins.
support for all kinds of mobile browser recording uploads and local uploads.
4, 91flv cloud transcoding advantages
one, without the configuration of complex operating environment, one-click installation can have upload environment, anti-theft chain mechanism, server-side automatic transcoding.
second, the super-powerful upload function including super-large file upload, breakpoint continuation, batch upload, seconds, drag and drop upload and so on you do not think of features, more gratifying is that these upload functions can be integrated into your website system, easy to own.
third, with video encryption address sharing function, through a short sharing address to achieve any device viewing.
Four, humanized multi-resolution adaptive speed environment switch, speed fast playback high-definition screen, low speed automatic playback low-definition screen, no manual intervention.
Video ads can be inserted into the video stream to easily achieve the end of the title and random ad insertion, even if the ads can be shared with a variety of images,swf, video ads, and background management, quite convenient.
Six, the real video file encryption (non-address encryption a kind of method), from the inside of the video file itself encryption, even if the video is downloaded can not be played by other software, with anti-theft chain and anti-download function, video unique protection is perfectly.
5. Seamless integration with digital resource sharing management system
    The Cloud transcoding server can combine with the multimedia resource application platform and other third-party resource application platform, upload the program automatic conversion format, for platform call, for upload to multimedia resource application platform of AV files, text class files, the system automatically call Transcoding service for format conversion, after conversion is completed, Automatically added to the platform, providing MP4 conversion of AV files , converting text files to SWF files, providing online browsing.
    transcoding Process: The user uploads the audio files to be transcoded, and sets the transcoding file format, System flags need to transcode the file, by the Transcoding schedule server polling the RMS system, to see if there are new transcoding tasks, when the transcoding dispatch server detects that the system has new transcoding tasks, Start the transcoding service process to transcode and transfer transcoding files back to the RMS system after transcoding is complete.
6, domestic and international mainstream technology comparison
    at present, foreign similar technology mainstream manufacturers mainly have the United States Elemental, and so on, they can achieve the highest rate of transcoding is 8 times times faster, and the price is much higher than domestic, so the domestic in this area is still in a relatively leading level.
