[FFmpeg-devel] [PATCH 1/5] avcodec: Require AMF SDK v1.4.23 or newer

[FFmpeg-devel] [PATCH 1/5] avcodec: Require AMF SDK v1.4.23 or newer

[Michael Fabian 'Xaymar' Dirks]

Increasing the minimum AMF SDK version allows us to support more recent hardware and drivers, which is necessary to fix some of the discrepancies between older and newer drivers on AMD hardware with FFmpeg.

[FFmpeg-devel] [PATCH 2/5] avcodec/amfenc: Set all color metadata for AMF

[Michael Fabian 'Xaymar' Dirks]

Fixes the color information in the output from the AMD encoder being wrong, which led to weird transcoding results. This problem appeared out of thin air, and I've been unable to tie it to a specific driver that supports my hardware. Unfortunately this requires AMF SDK version 1.4.23 or later, but it should still work fine on older drivers.

Theoretical support for HDR encoding is also now possible, although the implementation is not complete. I have no clear idea on how to generate AMFs HDR metadata structure, or where to even take this information from.

[FFmpeg-devel] [PATCH 1/5] avcodec: Require AMF SDK v1.4.23 or newer

[Michael Fabian 'Xaymar' Dirks]

From: Michael Fabian 'Xaymar' Dirks <michael.dirks@xaymar.com>

Increasing the minimum AMF SDK version allows us to support
more recent hardware and drivers, which is necessary to fix
some of the discrepancies between older and newer drivers on
AMD hardware with FFmpeg.

1.4.23 was just released in December, merely a month ago, correct?
Is there no way to maintain compatibility, or at least more of it, as
well as supporting new hardware?

Re: [FFmpeg-devel] [PATCH 1/5] avcodec: Require AMF SDK v1.4.23 or newer

[Michael Fabian 'Xaymar' Dirks]

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.
