I think it more like 7.0+git , description says it 35 commits ahead of
ffmpeg git snapshot that by itself 185 commits behind current ffmpeg.git
head ?

May be if we interested in encoding part of it just try to build this tree
standalone and pipe y4m to its ffmpeg binary?

Or pretend we have "7.1" already  by packaging this  git branch into
tarball named like release, putting it in thirdparty/src, patching our
configure.ac then see failures from API changes ? :)
