You say that its expected to break with inter-release versions of
ffnvcodec, but this is the opposite, it breaks with the release
version and works with git versions. So I'm not sure I understand what
you are saying.
Requiring a non-released version of a dependency was obviously a
gigantic oversight with the original patch, and as a result master is
currently broken for any reasonable setup avoiding those
"inter-release versions".
