Like OP, HW transcoding is broken.
I’m still on Android 9. Server Version is 1.25.3.5385. On the dashboard, it shows as transcoding, but no (HW) designation that I used to see.
I think this snippit from my log shows it:
Jan 23, 2022 18:41:19.506 [24168] DEBUG - Starting a transcode session C909627D-873E-4C00-A57A-E3C98D7F69CA at offset 0.0 (state=3)
Jan 23, 2022 18:41:19.507 [24168] DEBUG - TPU: hardware transcoding: enabled, but no hardware decode accelerator found
It’s definitely broken - transcodes work, but I’m getting buffering, stuttering, and artifacts in videos I never got before.
