I'm not sure exactly what you mean, but yes as near as I can tell it
only freezes after packet loss. It was hard to tell when it was
freezing because there wasn't a lot of motion in the video but I'm
going to play with it some more today and try to identify more solid
patterns.

After continued debugging I've narrowed things down somewhat. after
getting a picture from avcodec_decode_video2, I pass the data from the
picture to glTexImage2D, which is what
seems to be crashing. When I backtrace with gdb it says the the
address stored in picture-data[0]
is out of bounds. So
Alrighty,
I was relying on the return value from avcodec_decode_video2.
Basically I assumed that if it was 0 then the picture was valid.
However, I was curious about what got_picture was for so if changed:
if (ret 0)
to
if (ret 0 got_picture)
It no longer crashes, but instead seems to

There are lots of errors but mostly they just result in

when the channel is bad libav segfaults with:

Ok, I did some more testing, and the problem is not reproducible with
either ffmpeg or ffplay. I created a dump of the corrupted video
stream. When I play it back through my player it crashes but ffplay
just throws some new errors and then stops and the end of the video.
Any ideas?

After using gdb to run a backtrace it looks like my problem may be in
my OpenGL rendering. Sorry about that.
However, I still have one general question: When it comes to error
detection in situations like this, is dropping corrupted data at the
NALU level a good way to go, or is there a better
