[FFmpeg-devel] Changing media formats mid stream

[Roger Pack]

I've run into the case today where (if we understand it correctly) you
setup a directshow graph, it advertises media types, then when you
"start" the graph, it actually calls through and says "here's your
*real* media type".
Does ffmpeg internals have any concept of or support for a "changing
media type" at runtime? (any other suggestions for how to handle this
if it doesn't?)
Cheers!
