Nvidea Shield 2019 won't transcode (HW acceleration)

Server Version#: 1.25.3.5385

Following an update to PMS on Nvidea Shield around December 2021, transcoding no longer works properly. Hardware acceleration fails on ever attempt, falling back to Software Acceleration for transcoding. The transcode appears to work fine for about 60 seconds before it begins to buffer constantly. This happens on all clients (Android TV, Fire OS, android app, Roku etc.)

The files in question are x265 MKV files, they transcoded fine with hardware acceleration before. I have factory reset the SHIELD but the issue remains. Any suggestions or possible fixes?

You can only downgrade. So far, there doesn’t seem to be a solution.
Personally I gave up on PMS on Shield and have moved on again to a standard Intel based PC/Linux install.

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.

What was the last version on Shield that transcoding worked correctly?
