FYI, gst-plugins-libav-1.7.1 also fails with ffmpeg-3.0 I have neither found a patch nor an upstream bug for this problem.
https://cgit.freedesktop.org/gstreamer/gst-libav/log/ there are patches there that would definitely help, esp. since they updated their internal copy to 3.0
okey, so upstream patches backport properly to 1.6.3 and shouldn't break compatibility with ffmpeg 2.8 mind if I apply them? only one issue: they require an eautoreconf call; any advise there ? it is just standard eautoreconf or does it need special care because of gtk-doc or other gst/gnome specificity ?

Bug #574790. Patches are all from upstream, except gst-plugins-libav-1.6.3-minr-compat.patch which is a small #ifdefery more by myself to preser ve working options and passing tests with ffmpeg 2.8. done (got the 'go' from eva on irc)
