This prompts a few questions though: 1) How are these removed codecs handled in the library? Can we link an upstream application against FFMPEG in Fedora now and have it gracefully fail when it tries to access a non-free codec that was removed, or does the removal of these codecs create a different API that upstream applications would have to code around? e.g. does it mean they have to add conditional compilation for the specific codecs they need to use from FFMPEG instead of just around FFMPEG itself?FFMPEG has an API to query if support for a codec is compiled in or not. Applications should check if the codec they want to use is available. If an application just crashes, bugs should be reported that they should make correct use of the FFMPEG API.2) Is there an easily accessible list of the enabled codecs we can point upstreams to when talking about this?Applications should not care about our lists as it might change in future. They should use the API of ffmpeg to check if a codec is available or not. I hope that helps :-)
Shouldn't there be something like `Provides: ffmpeg-codec(foo)`? Not sure if that would be useful.
