sunshine for android or chroot/proot

[YourSandwich]

Hello there, the idea is, since some poeple are running desktop environments in termux with proot or like me in chroot trough linux deploy. Sunshine could help archiving low latency remote desktop since vnc or rdp is slow.

The two main methods currently to have a gui from proot or chroot is either trough vnc/rdp or XServer XSDL(Android app)

Since normaly 3d acceleration is not avillable with proot or chroot it would need to run with software. I can test everything with my Galaxy S10+ exynose 6GB Ram 512ROM.

After installing/compiling it now trough aur il get an output -> filesysem error: directory iterator cannot open directory: No such file or directory [/dev/dri]

We should probably aim for proot because everyone can install linux with proot and termux, for chroot and linux deploy, root is needed. If it works on proot then it will work on chroot but the different way it may not.

That sounds awesome. 👍

It's caused by code that assumes /dev/dri exists.

This'll be fixed eventually, but for now, you can disable this piece of code with the cmake parameter -DSUNSHINE_ENABLE_DRM=OFF

It relies on files existing in /dev/dri anyway, so no loss there.

The first problem got fixed with setting the encoder to software in sunshine.conf

after playing a little bit more around i got it work to the point that shows this error ->

In order to make sunshine see display=:0 is. I have to export my display to localhost -> "set -x DISPLAY 192.168.0.100:0" and start xfce4 with "startxfce4" but to start xfce4 i also need this XSDL thing. now sunshine sees display 0. I also had to uninstall wayland-protocols wheil doing cmake without sunshine wants the variable WAYLAND_DISPLAY. arch needs the wayland and wayland-protocols even when wayland is not working or in use. After all this steps il got this error.

You can try setting min_threads=4 where you replace 4 with whatever number you want.

This forces Sunshine to multithread with the software encoder.

Still, I don't expect much improvement, it's a smartphone after all, I think you'd have better luck if you use a hardware encoder.

If you're lucky, ffmpeg has support for whatever hardware encoder is used on galaxy S10+

your right i forgot vnc is not encoding that are different technologies. But the idea works :) i play around and let you know if il get it smooth. Thank you for help!

played a little bit more and. I can now run it without XSDL with "Xvnc :0 -display :0 1920x1080x24" but now i noticed that sunshine is controlling the mouse of my phone and not of the xfce4-session itself.

Latency is now extremly high even more then trough vnc with same quality, il try to play with encoder settings maybe this changes something but i thing it is the fault of xserver.

If you are using software encoding you might be able to leverage arm NEON instruction if your cpu supports it.

Your encoder would also need to support this though.

Sunshine makes use of uinput to emulate mouse, keyboard and gamepad.

Old code made use of X11's API, but that wasn't useful for games.

Maybe you could ensure X11 has exclusive access to the mouse and keyboard.
