[Libav-user] Write raw RGB frames to file

[Max Göttner - d.stream]

Hi.
I read frames from input files, use swscale to have raw rgb images. I would
like to write these images to a 
Mkv container, keeping the frames in raw rgb. How can this be obtained? What
codec do I have to use?
I tried CODEC_ID_BMP but I couldn't find any ressource that tells me what
settings go together with a specific codec.
Thanks for any suggestion,
Max.
