We recently were in an unstable period; I believed that this would
extend to the release, but other people disagreed with this. I actually
had one more patchset that breaks the avpriv-ABI (i.e. it would not
force user apps linking to our libs to be rebuilt; rebuilding the ffmpeg
libs is enough). Will see how that fares.
