And you want to just dump the packets payload in a file? With the ffmpeg

Then I suggest to implement that as a ffmpeg option:

	ffmpeg -dump_stream:0 stream0.bin -i damaged.mp4 -f null -

It is not efficient nor robust to have the packets go through all
ffmpeg's and libavformat processing only to have an option to disable
that processing.
