[FFmpeg-user] feeding frames to ffmpeg manually?

[Csillag Kristof]

Hi there,

I am interested in using ffmpeg in a very non-standard way.

There is an application that is currently displaying images to an X11 
display.
I would like to modify application, so that the pictures are not 
displayed via X,
but fed into ffmpeg, and encoded as frames of a H264 video stream instead.

How do I do this?

Obviously, I will need to write code, but that's no problem; the 
question is where do I start?
Where can I find relevant documentation, and/or code examples? How do I 
need to talk to?

Thank you for your help:
