[Live-devel] How to encode and stream from a raw RGB data source?

[Shaswata Jash]

Hi Wisem,

Indeed this is possible using live library. 
You have to encode your raw RGB frames to MPEG4 (ISO) video using some third party encoding library (e.g. open source ffmpeg). Then these encoded frames have to be fed to live library. To know about how to use these encoded frames in live, you could check out my replies to a topic named "Problem trying to use libavcodec and live555" in live mailing list. 
Also, i think there should not be any problem regarding resolution in ISO-MPEG4.


With regards,

  Hi, I have written an OpenGL application that renders a 3D animation in a window. Now I would like to encode this animation and stream it using liveMedia library... But for this I think I have to encode my RGB raw frames (output from my OpenGL app) in a format suitable for the liveMedia streaming library. What format (and what library) I can use for encode my raw RGB frames (I would like a format that can support strange resolutions too, not only the standard ones)? Can you suggest to me an encoding format that is perfectly suitable for liveMedia library? For now, my app renders to an '.avi' file with 'Video for Windows' library and the video stream is encoded with MS-MPEG4 codec, but I would like to render, encode and stream in real-time. Do you think it's possible? Can liveMedia library reads directly from an AVI source?
  Any info or suggestion will be very appreciated...

  Thank you in advance,
      Wisem
