This is pretty clearly a bug in gstffmpeg (there are similar bugs in
alaw, at least, and possibly others). The documentation has always
been clear, that this function takes ownership of the caps.
However, obviously we don't want to just break everything suddenly.
I'd suggest: revert this change, fix all the plugins that rely on the
old behaviour, then after the next round of releases, reinstate the
fix, so we stop leaking caps.
