Why is AVC decode using the software MFX decoder instead of my hardware GPU (Radeon RX580)?  I can see AVC is correctly using the NVIDIA GPU in my "sender" to encode the video stream, but the "receiver" is clearly doing software decode on the CPU.

 

Here are the relevant configuration entries:

 

## Reduce network bandwidth using the H264 Codec
Rgreceiver.ImageCodec.IsH264Enabled=1

## Offload H264 encoding to GPU: 0-CPU 1-GPU
Rgreceiver.ImageCodec.UseGPU=1

 

Here are the relevant log entries:
