[GEM-dev] pix_movie reads incorrect number of frames with huffyuv AVI

[B. Bogart]

Hey all,

I've had the best HD results with huffyuv in an AVI container, but
something is going wrong with the number of frames.

ffmpeg and mplayer both see the proper ~5310 frames (~178 seconds), but
pix_movie reports only 750 frames.

Everything works fine with small files (640x480) but with these highres
files (1280x960) I am only able to play the first 750 frames.

Can someone take a look?

Otherwise I'm stuck with using mjpeg.

Thanks.
.b.
