[vlc-devel] Re: How to modify to hardware codec for MPEG4 and so on?

[j y]

Hi,
  From the information I got, the codec and demux and almost all play function will be handled by the hardware, what I need the VLC to do is just reading the mpeg4 steam from RTSP or file and writing to the hardware.
  I noticed that the libmpeg2 is only a decoder, the demuxer lies in the demux directory,
  how can I take over the demux and decode and output work to my own module?
   
  Thank you and best regards.

Well, you should develop a codedc module to override the ffmpeg and
libmpeg2 ones. That shouldn't be too complicated if you hardware chip
provides a decent high level API. However, I'm not sure VLC's codec
modul API is that documented. I would suggest to have a look at other
codec modules, libmpeg2 for instance, as a example. Don't hesitate to
ask further questions.
