The 'interleave' filter is not completing. Does it not recognize end-of-frames for [C]? What do I
need to do?
Note: I've tried runs with 2 differing stream sources.
Note: When I break out at the end (Ctrl-C), the target video plays, so the problem is not

Maybe it’s because it’s the last RX Polaris card they released before moving
on, the video encoding/decoding hardware changed. But then again it is the
exact same gpu

I tried VAAPI with a RADEON 580 on Linux. It was intermittent at best.
I wound up using Vulkan with success.
This is the hwaccel command I was using for transcoding.

I don't know about that, but i am more confused why this build from git
reporting only vdpau as available hardware acceleration methods,
My distribution packaged one reports:

vdpau
