You still didn't provide debug logs, but this specific problem is most
likely https://bugzilla.gnome.org/show_bug.cgi?id=740222

The only options you have here is between libav copying, or you doing
the copying if needed. You can't (in general) have writable frames
downstream of the libav decoders as they like to keep another reference
to the frames for constructing the next output frames (i.e. to use them
as reference frames).
