Amarok fails to build due to changes in the FFMPEG API, with the errors: 

```

                    decodedFrame = avcodec_alloc_frame();

I am using the kf5 branch. 

Reproducible: Always
Comment 1 Myriam Schweingruber 2016-05-19 14:18:38 UTC 
And that is the problem: the kf5 branch is still pre-alpha, there hasn't been not even a technical preview because many things haven't been implemented yet. So it is way too early to report bugs against it. You are of course welcome to help in the development.
Comment 2 Gregory M. Turner 2016-08-21 08:37:20 UTC 
That may be one problem; another might be that maintainers, early adopters, and eventually amarok's own developers will need to independently track down and test:

https://build.opensuse.org/package/view_file/openSUSE:Factory/amarok/amarok-ffmpeg3.0.patch?rev=99,

after they came here to try to determine if a reasonable solution had been identified, yet, by the kf5 amarok community.  Thankfully, both problems have the same solution.
