A better solution was found upstream:

http://anonscm.debian.org/cgit/pkg-multimedia/libav.git/commit/?h=upstream&id=0ec75a04e5fc714bc3cd6e2a6b783e6df834ad01

This was part of libav 10.2, which was uploaded to Debian first, and
then copied over to Ubuntu. This is why I'm so confused that you are
experiencing this problem in Debian, but claim the problem was fixed
in Ubuntu.

Can you please recheck that you are in fact trying to use Libav 10.2
and not 10.1, and clarify what's going on?

Note that upstream was not 100% sure if that is the right fix, as we
lack the hardware to test this properly. Feedback to
libav-devel at libav.org on the patch is very welcome.
