Thanks; I managed to reproduce the problem, now.

I think I understand what's going on...
If I got it right, the conversion between IMGFMT_* and PIX_FMT_* is the
following:
1) IMGFMT_RGBA ---> PIX_FMT_RGBA; IMGFMT_ARGB ---> PIX_FMT_ARGB;
IMGFMT_BGRA ---> PIX_FMT_BGRA; IMGFMT_ABGR ---> PIX_FMT_ABGR
2) IMGFMT_BGR32 ---> PIX_FMT_RGB32, and IMGFMT_RGB32 ---> PIX_FMT_BGR32
(because mplayer and ffmpeg use different naming conventions)

Michael, is this correct? I hope I did not misunderstand this stuff
again :)

So, since there is this RGB32 <---> BGR32 "swap" between mplayer and
ffmpeg, the isRGB() macro should return true for PIX_FMT_BGR32, and the
isBGR() macro should return true for PIX_FMT_RGB32... :(
After changing this (and after fixing a bug in my patch that I just
found --- I'll post it tomorrow), the test seems to work ok.
Michael, does this make sense?

I have no time now, but tomorrow I'll do other tests and post an update.


			Thanks,
				Luca
