[Issue]: Slow decoding and large latency spikes on Orange Pi 5 (rk3588s)

[coffeebird]

Describe the bug

Testing Orange Pi 5 as a moonlight client but seeing slow decoding and massive latency spikes

screencap showing latency

I've tried a few different tests using both linux and windows hosts with nvidia and amd gpus, all over gigabit ethernet. Tried various bitrates and codecs. There were dropped frames and massive spikes like in the photo above in each test.

Windows Sunshine host nvidia gtx 750 / Orange Pi 5 Android 12 Moonlight client h.264: 5-7ms (dropped frames and 100ms+ spikes)
Linux Sunshine host amd rx580 / Orange Pi 5 Android 12 Moonlight client hvec: 9-12ms (dropped frames and 100ms+ spikes)
Linux Sunshine host amd rx580 /Orange Pi 5 Android 12 Moonlight client h.264: 6-8ms (dropped frames and 100ms+ spikes)

By comparison, I tested the same windows host and orange pi android 12 client using parsec, and the performance was night and day,
Windows Parsec host nvidie gtx 750 / Orange Pi 5 Android 12 Parsec client h.264: 2ms (no dropped frames and no spikes)

Finally, after compiling moonlight-qt and ffmpeg-rockchip for armbian with a vendor kernel, I was able to get almost identical smooth performance as parsec.

Linux Sunshine host amd rx580 / Orange pi 5 Armbian moonlight-qt client hvec: 2ms (no dropped frames and no spikes)

I don't know what else to test. It's great that moonlight works well on the Rockchip rk3588s in linux, but it would be better for my needs if worked just as well in Android.

Could this be an issue with the moonlight android client? Appreciate any help or insight.
