MediaFoundationDxgiCapabilities: with AMF SDK H.264 encoder related data

Posted on by Roman

Yet another post on AMD AMF SDK and hopefully a helpful tool reference. I updated one of the capability discovery applications (MediaFoundationDxgiCapabilities) so that it includes a printout of AMFVideoEncoderVCE_AVC related properties similarly as they are printed for Nvidia video adapters.

Information includes:

  • runtime version (and its availability in first place!)
  • maximal resolution, profile and level supported
  • formats with respect to capabilities reported on Direct3D 11 initialized component; specifically the data show which surface formats the encoding component has internal capability to convert on the way to hardware encoder

It looks like this tool was not described in detail earlier so one could find other DXGI related information as well (such as, for example, order of enumeration of DXGI adapters depending on whether an app is running on iGPU or dGPU on a hybrid system; DXGI desktop duplication related information).

This is reported directly from AMF as opposed to information received from Media Foundation API (which is also partially included though). On video encoders reported via Media Foundation, not just H.264 ones, see MediaFoundationVideoEncoderTransforms: Detecting support for hardware H.264 video encoders.
