Thanks for catching that.

Libavformat uses libchromaprint since version 7:3.0-1, while libchromaprint
started linking libavformat only in the last uploaded version 1.4.1-1.
Previously only libchromaprint-tools used libavformat.

While it would be easy to disable chromaprint support in ffmpeg, that
would be a feature regression, so I'd rather not do that.

Hence I'm reassigning this to chromaprint.
As this is not the time in the release cycle to let such issues slip
into testing, I'm raising the severity to serious to prevent testing
migration of the new chromaprint, until this issue is solved.

Now the question is, why did libchromaprint start using libavformat?
Can this functionality be moved to libchromaprint-tools or at least
be disabled?

Best regards,
Andreas
