Hi Mark,
Did you still encounter hung issue?
If yes, could you share me with your play and transcode streams and command
line,
then I can try to reproduce at my side.
Thanks & Best Regards!

Can you explain what the requirements are for using this (hardware, firmware,
software)?
From what I can find it should be on Polaris and Vega, but I haven't succeeded
in getting it working on Polaris.
Yes, polaris and vega10. For polaris, you'll need a kernel that
enables the uvd enc rings. Patches went upstream last year, 4.14 I
think? 4.15 is a good bet.
Ah, that's where I'm going wrong - despite the dates it's not actually in 4.14,
so I need 4.15.
As for the polaris firmware, you'll need
version FW_1_130_16 or newer:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=2a713be25a44bd6cec90d8affc54b246a2ca9c7b
Right, I have the encoder working with 4.15.2 on an RX 460 / Polaris 11 with
firmware 1.130_16.
There seems to be some issue with using both encode and playback at the same
time? It hangs the amdgpu driver and all userspaces processes interacting with
it become stuck and unkillable, requiring a reboot to recover. It's completely
repeatable, and only needs a few seconds to die when both mpv (playback) and
ffmpeg (transcode) are running at the same time.
There is no message at all from the stuck driver, but I end up with hung tasks
like:
