"Error: failed to open X display" on OrangePi #856

Open workaccount23 opened 2 years ago

_NVidia Geforce Experience version: 3.25.1.27 Moonlight Embedded source: compiled from source, after installing dependencies manually Moonlight Embedded running on: OrangePi Zero 2 Moonlight Embedded running on distribution: OrangePi 3.0 bullseye

Verbose output -verbose of Moonlight Embedded:

What is the expected result? I would expect the streaming to start

What happens instead of that? Steam Big Picture opens on PC, but the stream doesnt start.

If I use the -app options the desired game starts properly on PC, but the same error arises. Is this error due to the OrangePi or is it something I could have messed up?

It looks like you're trying to run moonlight-embedded from a session that doesn't have X running. Additionally, it looks like Moonlight Embedded is trying to use software decoding, which is unlikely to give you acceptable performance on that hardware even if it did work.

I'd suggest checking what libraries and/or patches are required to support hardware accelerated video decoding on the Orange Pi Zero 2. Decoding code on most embedded Linux devices tends to be very vendor-specific, because everyone invented their own standards and libraries. That situation is getting better with V4L2, but it's not widely supported yet.

If you can find a new enough version of FFmpeg that can do hardware accelerated decoding, you might have more success using Moonlight Qt which uses FFmpeg for hardware decoding.
