[Live-devel] How to add the H.263 video stream to the server?

[Chen Weisi]

hi Ross Finlayson:
      Thank you very much for your suggestions on how to add H.263 video.
      In your letter, you wrote as follows:

    I have worked on that for a few days. Here, my dada is just coming from a file,
"ByteStreamfilesouce" can be used directly .A can you tell me what is the use of
"H.263plusVideoStreamFramer" class which you want me to creat. I guess that 
this class is to demux the H.263 video data to frame and get the video frame which will 
be used in RTSP packeting. If I am wrong ,please let me know it. Thanks again.
   
    By the way, I know that Mplayer and VLC use livecom lib on rtsp part ,and 
it can work very well on the two players. The livecom lib becomes more and more popular. 
But mplayer has meet some patent problems , and VLC meets the same prolems 
recently. I am anxious to know is there any patent problems in  livecom lib? Thanks.
