Has anyone got any status on that subject?
Anyway, I've managed to increase the number of max
reference pics (at least from what I could understand from the code), from
16 to 32 in h264.c, and it seems to help a little (the stream above now
decodes to the end).

btw, nice symbolic constants would be nicer than things like that spread all
over the code:
for (i = 0; i < 16; i++) ...
Picture* delayed_pics[16]; etc... :-)

The above stream now decodes ok, but the following one fails with
"getbuffer() failed" and consequently (no checks for the getbuffer calls)
SIGSEGV.
I assume there is some leak somewhere?

Again, I'd appreciate any help on the subject.
