Source: ffmpeg
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)
X-Debbugs-Cc: kerdek7@gmail.com

Dear Maintainer,

This source package requires the debian package libunwind-dev as a build dependency, but it is not installed by apt-src. This usually means the build dependency needs to be added to the BuildDepends field of the package data.

Thanks,
Ted Stier

Lacking an answer to the question, I'm closing the bug report.
