Hi, 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:
http://img26.yfrog.com/i/h264artifacts.jpg/ 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. _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
