I'm doing something like that. I stream media from up to four
AXIS-Cameras using RTSP and libav 2.1.4 w/o decoding the
frames/packets, just looking at their flags, and cut them into pieces
every let's say 60 seconds, so the resulting files don't get too

I'm not sure if you will get away that easiliy. I had to rescale
DTS/PTS and durtion in order to be able to play those clips.

But the image and audio data is absolutley untouched.

If you want me to post some (the relevant parts) of my work, just let
me know. I've written a very small test program to test the code bevor
trying to get it work in our "big" SW. Probably that can help you a
little bit.
