Hi, please forgive me if this comes through twice. The list was down
earlier, it's back up now but my email isn't showing up in the
archives.

I'm getting some colour artefacts when decoding H.264 using ffmpeg
built from source. When I use the ffmpeg package for Fedora 9 from
livna, it works fine. I get the same artefacts when I compile my
application on Windows - whether I link against the pre-built binaries
or build the libs myself.
There's a screenshot of the effect here:

When I'm looking at an IDR frame, it's all purple. When I'm on a
p-frame, it looks like the screenshot above. The green and purple
coloured patches move around, seeming to follow the areas of motion.

It seems that the Y plane is fine but the U and V are corrupted
somehow. Here are my configure options on Linux:

./configure --prefix=/usr --incdir=/usr/include/ffmpeg
--libdir=/usr/lib --mandir=/usr/share/man --arch=i386
'--extra-cflags=-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2
-fexceptions -fno-common -fstack-protector --param=ssp-buffer-size=4
-m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables'
--enable-avfilter --enable-avfilter-lavf  -enable-postproc
--enable-pthreads --disable-static --enable-shared --enable-gpl
--disable-debug --disable-optimizations --disable-stripping
--shlibdir=/usr/lib --cpu=i386  -disable-amd3dnow --disable-mmx
--disable-sse

Any thoughts on what might be causing this?

I really need to use the latest because it fixes another issue I've
been having with the Fedora rpm - I won't go into details here as it's
not really relevant to the problem.

Thanks, Chris.
