Comment:
It seems that part of code is some hack for broken files from the old
times.
I have sent a patch which eliminates it more completetly.

Also note that for ffmpeg tests I needed to specify -scan_all_pmts 0 to be
able to test this, otherwise it does not really make a difference, because
ffmpeg implicitly sets it to 1 which ultimately causes the code in
avformat_find_stream_info() to effectively read the whole probesize during
probing.
