Hi Bouke, No the question was not for you :) But for people who are in position to accept patches.. But probably this is the wrong mailing list.. I should have asked the question on ffmpeg-devel
However I am fairly certain that this is the source of your problem... Maybe I can do a test with your file with the patch applied...
