Subject: bug#23256: vlc not building after update to ffmpeg 3.0
Date: Sat, 09 Apr 2016 14:21:39 -0500	[thread overview]
Message-ID: <87y48mvb98.fsf@dustycloud.org> (raw)

vlc is failing to build after the update recently to ffmpeg 3.0.  I
verified that it builds prior to this change.

Should we include an older version of ffmpeg to build vlc with for now?
Or should we try to figure out what to do to to get vlc to build with
ffmpeg 3.0?  Maybe for now we should do the former for the aim of the latter.

Here's the output while attempting to build.
