Libav provides cross-platform tools and libraries to convert,
manipulate and stream a wide range of multimedia formats and protocols.
This package is not eligible on Fedora because it needs unavailable packages.

Scratch builds on f24-free:

There is a configuration problem by activating "opencv" support; i'm
contacting
upstream.

FYI, why do you need this library and not ffmpeg instead ?
You are using a build suffix, so it should co-install with ffmpeg-libs but then
you cannot mix dependencies build with ffmpeg and thoses built with libva.
We probably need to adapt %{name}-enforcing_system_crypto_policies.patch for
ffmpeg. Can you send your patch to ffmpeg upstream also (if needed).

I used ffmpeg too; 'libav' would be simply a (good?) alternative.
For example, 'devede' uses both 'ffmpeg' and 'avconv' (from
libav).

I followed instructions from Fedora guidelines. Let me see if i know how to
patch 'ffmpeg'.

'libav-11' looks incompatible with 'opencv-3.1.0', it's disabled on
Fedora >24.
Package ready for reviewing.

Is there any real need for this package in RPMFusion? FFmpeg is almost 100%
backwards compatible with libav. The one package that I thought still used
bundled libav (gstreamer1-libav) actually switched back to FFmpeg last year.
Most of the symbols in the provided libraries have the same names, so you'd
have to be extremely careful not to end up with another package depending on
both ffmpeg-libs and libav in the future. Since libvdpau-va-gl (the
vaapi-to-vdpau bridge that's required to use Intel GPUs via vdpau) depends on
ffmpeg-libs, this might be trickier than you think. Even renaming the libraries
and their sonames won't help here. You'd have to rename the symbols, too.
So, I'm against including this package in RPMFusion because it introduces a
world of potential trouble without any clear technical benefits.
But of course I'm open to any counter-arguments.

We could set Conflicts tag to prevent 'libav' installation if FFmpeg is already
installed (and viceversa).
I don't know which one is the better today, but upstream says that 'FFmpeg'
and
'libav' are different especially at API level.
I think that if it's possible, we can provide both and leave the choice to the
developers.
