 happy to. Even if it's about code in gst-plugins-libav ... or anything
 really. (I don't know much btw, but willing to try)

 The fix for this is likely this commit in gstreamer:
 http://cgit.freedesktop.org/gstreamer/gst-
 libav/commit/?id=30a4a28793f2e0ff08aaea368b7c14317ac2ca21

 There seem to be other related fixes in gstreamer too
 i dont think theres any sense in debuging this further before you ensured
 that your gstreamer contains these fixes
