title: raw h.264 bitstream decoding
body: <p>I can get raw h.264 frames from a camera. (it does NOT contain any network headers, for example rtsp, http).
  They are h.264 raw data.
  And I push these data to a queue frame by frame.
  I googled many ffmpeg example which uses avformat_open_input() with either local file path or network path.
  And I can see the video while I save the frames to a file and using avformat_open_input().</p>
  
  <p>My problem is that I want to decode the frames realtime, not after it is saved as a file.
  Does anyone have any idea on this?</p>
  
  <p>Thanks!</p>
