As you might expect, I tried lots of different options. Looking at the
output again, it looks like my problem is interpreting the hex dump. It
appears that it put it into 16 bit intel words which is why nothing
looked right.
0000 0100 6467 etc instead of
00 00 00 01 67 64
Which makes a whole lot more sense to me. Sorry for the noise, and thanks!
Last question, is it possible to dump avcc/mp4 stream? The opposite of
h264_mp4toannexb?
