I'm decoding a H264 video stream using Media Foundation. It works, but performance is really poor on both Windows (desktop) and HoloLens 2 (UWP). Decoding a single 1920x1080 frame takes 30 ms on a fairly powerful PC, 100 ms on the HoloLens .
I'm wondering if it's using software rendering instead of hardware rendering. Any idea on how to make sure that I'm doing hardware decoding, or any other hints on how to improve performance?
The code is here:
