I just wanted to ask the current status of this issue, since I saw that
the problem still exists in the current git version.

I have tested the patch suggested by Baptiste Coudurier and I'm using it
extensively without problems. Is there anything I could do to help
getting that fix into trunk? :)
e.g. re-post this issue on ffmpeg-devel?

Thanks and regards,
Peter B.
