Yes, I have ddagrab->amfenc working with just fixing alpha channel, but AMF
encoders sometimes use shader, sometimes VCN for color conversion - it
depends on HW capabilities. I would suggest to always set bind in ddgrab to
D3D11_BIND_SHADER_RESOURCE, because this is no reason not to do it.

The purpose of this patch is to fix an issue with feeding ddagrab output
to AMF directly. The output of ddagrab might be BGRA, AMF supports this
input, but failed to encode due to missing mapping from AV_PIX_BGRA to
AMF_SURFACE_BGRA in amfenc.c
DXGI isn't firm to distinguish between RGBA & RGBX, so it is safer to
support both to avoid failures like with ddagrab.
See patch just sent to fix the bug in ddagrab that it incorrectly advertises an
alpha channel.
Do you have ddagrab->amfenc working with just something to fix the alpha
channel? To make it work I also need to mess with the bind flags because amfenc
wants to use the textures as shader resources.
This has been noted as a problem before, where a proper fix would require large changes
in the format negotiation setup and so it hasn't been done. I'm wondering whether adding
"-bind_flags shader_resource" option to ddagrab would be a plausible hack for
these cases, or whether that's a bit too obscure for an actual user?
Thanks,
- Mark
