Does Media Foundation Transform support h.264 video decoding in Windows?

I'm trying to decode h264 video in windows using Media Foundation.

I cannot use the source resolver as I need to decode one frame at a time from a buffer - hence planning to use Media Foundation Transforms (ProcessInput and ProcessOutput) directly.

Is the h.264 decoder supported in Windows? The goal is to only decode the frame data into a buffer and not to render it.

Also I'm assuming the simplified steps are as follows - correct me if I'm wrong.

• Initialize MF
• CreateDecoder (CoCreateInstance or MFTEnumEx)
• transform->SetInputType and SetOutputType
• Provide input through ProcessInput with an IMFMediaBuffer
• If it succeeds ProcessOutput to an MFT_OUTPUT_DATA_BUFFER
• Extract DXGIBuffer from the sample to access the decoded frame data.
