Comment 1 Sebastian Dröge (slomo) 2009-09-19 09:21:39 UTC

I know that there already is a bug about this but I can't find it now... also the ffmpeg stuff looks similar to bug #595590 that you recently filed.

Comment 2 Sebastian Dröge (slomo) 2009-09-22 06:43:21 UTC

The only relevant parts here are, everything else is from bug #595590.

Comment 3 Sebastian Dröge (slomo) 2009-09-22 06:48:40 UTC

I can reproduce many very similar valgrind warnings when using x264 from mencoder so this is most likely a problem in x264. Please file this bug there :)
