gstreamer 1.8.3 incorrectly removes some decoders and encoders when built against ffmpeg 2.8.10

Status changed to 'Confirmed' because the bug affects multiple users.

Did you try 1.8.3 without the patch or just 1.8.2?

Only tried the downgrade (may have assumed the patch was the only change
Could certainly try reverting current source

Right, there's a new upstream version in there too. I don't think it'll build if you remove the patch though - that's what it's for. Might need to bisect & reapply it each time.

Correct, I see that now. It may be that gst-libav-1.8.3 with ffmpeg
2.8.x is just going to have this issue which I can extend to

.wma; .ape; .tta; .mpc; .m4a(alac), maybe a couple more.

Any negitive reason to just returning to 1.8.3 for the libav plugin?

So the gist is the patch allows building the source but the created plugin is functionally useless.

I reproduced this, it's a problem with the combination of the shipped ffmpeg and 1.8.3.

Hello Doug, or anyone else affected,

Accepted gst-libav1.0 into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gst-libav1.0/1.8.3-1ubuntu0.2 in a few hours, and then in the -proposed repository.

Yeah, version 1.8.3-1ubuntu0.2 brings the sound in WMV videos back :)
Thanks for the fix!

I had the same issues with other wma files and with 1.8.3-1ubuntu0.2 it works now.

This bug was fixed in the package gst-libav1.0 - 1.8.3-1ubuntu0.2

This bug affects yakkety yak but I don't see an update for that platform.

Am I wrong or this was missed?
