The first thing you have to do is check that AVFormat is recognizing a
transport stream.
printf("format %s\n", pAVInputFormat->name);
Make sure the stream starts with byte 0x47 otherwise the probe
function is likely to fail.
I did not do any mayor modifications to your code to get it to work,
with transport streams. Post you bin file somewhere, so I can take a
look. Make sure it can be played by vlc, ffplay or mplayer. I will
take a look.
