Hardware transcoding is erroring on the web interface. I've tried both stable and pre-release channels versions with the same result. Attempted pre-release version is 2021.09.19.1731
System: i5-11600K, Arch Linux with kernel 5.14.6, intel-media-sdk is installed and appears configured properly per Arch Wiki.
Below are logs with various setting changes for the hardware transcoder (I didn't see a way to attach logs). It appears deinterlacer set to blend or linear, rather than hardware gets closer to encoding, yet still errors.
Deinterlacer set to blend:
