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?
