OpenCV stream captured CAM with H264 codec (mp4)

I like to stream webcams captured by opencv. I am thinking of a solution with ffmpeg and live555 (bad they are not so well documented). My problems:

  • How to convert captured images to H264 format to match peak / second. If it is in a loop, I get over 25 images / sec, and the video is fast.

  • How can I directly transfer the converted H264 stream over the network via rtp / rtps or similar.

Thank you for your help!

  • This is a common problem.
    • If you do not need to distribute your software (private use / server side / open source), you can use FFMpeg compiled with x264 encoder , there is a configuration flag for the FFMpeg config script.
    • If you need to distribute your software, I do not know any licensed LGPL library, I believe that there is no such library. You will need to use some kind of paid solution.
  • You should implement DeviceSource.cpp, see DeviceSource.hh and use it as FramedSource.

Edit : Apple discovered the video encoder API by allowing access to the h264 frame stream in iOS8

For an example of using x264 and Live555 for encoding and streaming frames, see the following:
