Is there no way to maintain compatibility, or at least more of it, as well as supporting new hardware? - Hendrik
I'm unsure what compatibility is broken here, since AMD's AMF SDK does not verify the drivers AMF Runtime, or the other way around. At least from my experience writing an AMF integration for another software and testing with current hardware, older Drivers work just fine. If necessary I can port the entire compatibility structures I built for another open source software to FFmpeg, which would extend the minimum driver version to 19.7.1 and would include drivers that cause stack and heap corruptions, weird dlopen/LoadLibrary issues, and more. If you meant compatibility with older versions of the SDK, it is possible. Since this is meant to add new features, increasing the minimum SDK version felt line the better choice than allowing users to build amfenc "wrong" and getting a completely different set of options out of FFmpeg.

It appears that this set of patches was overlooked, could I get some eyes to look at it again, and perhaps even have it merged into the main tree? I've been using it in production for a bit now, as it fixes most of the encountered issues with amfenc.
