All the critical and important bugs are good candidate to be fixed for
the next release. I propose to focus on this bugs for this week, try
to fix them and release anyway, there is not much point in delaying
more and more the release.

Follow a list from https://ffmpeg.org/trac/ffmpeg/report/1:

I don't know if #157 was already fixed.

(BTW I'm always in favor of the idea of a monetary "reward" for each bugfix).
