Hey guys,

I've been writing an avi player using OpenGL/GLUT and the avifile-0.7librar=
y.
I looked for a way to specify a Draw callback, but that doesn't seem to=20
exist nowadays. So I wrote my own video renderer class (implements=20
IVideoRenderer) and added an instance of that to the AviPlayer's list of=20
video renderers.

All of this works fine, but not when using the XVID4 codec. The player=20
starts up, but segfaults before displaying any frames. I ran GDB, and found=
=20
it segfaulted in the process running the yv12_to_yv12_xmm function:

Program received signal SIGSEGV, Segmentation fault.

>=20

It's quite frustrating, because the aviplay example works fine using the=20
same XVID4-encoded videos that make my program segfault :) Of course, the=
=20
aviplay example uses IAviPlayer2, which does video rendering for you.

Any help would be _greatly_ appreciated

Regards
Karl
