Package: ffmpegthumbs
Version: 15.07.90-1
Severity: important
Tags: patch
User: pkg-multimedia-maintain...@lists.alioth.debian.org
Usertags: ffmpeg2.9
Dear Maintainer,
your package fails to build with the upcoming ffmpeg 2.9.
This bug will become release-critical at some point when the
ffmpeg2.9 transition gets closer.
Attached is a patch replacing the deprecated functionality.
It also works with ffmpeg 2.8.
Please apply this patch and forward it upstream, if necessary.
These changes are non-trivial and should be runtime-tested.
Best regards,
Andreas
