[Ffmpeg-devel] Programmatically copying a video stream

[Joel Reymont]

Folks,

This may seem like a silly exercise but how to I programmatically  
copy an input video stream to output? I'm trying to emulate what  
ffmpeg does with the "copy" codec. Basically, I'm trying to overlay a  
new audio stream on top of existing video.

I thought I would just need to copy the settings from the codec  
context of the input video stream to the same of the output video  
stream and then av_read_frame(in, &pkt), immediately followed by  
av_write_frame(out, &pkt).

I get "error, non monotone timestamps 47351 >= 47351" after writing  
the second frame, though.

What am I doing wrong?

	Thanks, Joel
