Not sure why this is being posted now, but, libav development has been abandoned since 2018.<p>By far the most damaging fallout of this was the demonstration of how much power Debian package maintainers have. The Debian ffmpeg package, for a while, printed the "error":<p><pre><code> *** THIS PROGRAM IS DEPRECATED ***
This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.
</code></pre>
No part of this was true, and Debian eventually dropped avconv in Stretch/9. but that this falsehood was allowed to stay in the package for so long really left a bad taste in my mouth about Debian is run.
