Homebrew RELEASE Moonlight-libretro core for Lakka Switch

[rock88]

Why this port for Lakka Switch?
Currently not possible create a normal port for Horizon OS (ffmpeg lib without hardware acceleration, enet lib don't work properly, etc..), so I'm starting porting Moonlight to RetroArch as libretro core.
Also Moonlight port available for L4T Ubuntu, but use desktop OS on Switch is very confused for me. Android has issue with Wi-Fi, so it also unusable for me.

Features:

1. Stable framerate at 720p/1080p resolution and 30/60fps (bitrate setting included);
   
2. Good sound;
3. UI similar to Moonlight PC;
4. Maybe some else? xD

Installing (Nintendo Switch)

1. Install Lakka
2. Download latest Moonlight-libretro release
3. Put moonlight_libretro.so to lakka/storage/cores directory on your SD card (create dir if it not exist).
4. Choose Load Core and select moonlight_libretro.so, then push Start Core.

Controls (Nintendo Switch)

1. Move cursor with move finger on touch screen
2. L/R + tap on screen - Left/Right mouse click (allow to move cursor)
3. ZL/ZR + tap on screen - Left/Right mouse click (without move cursor)
4. L+R+Down - exit from stream (and close current app)
5. L+R+Up - exit from stream (without closing current app)
6. L+R+Left - sent Alt+Enter to host (for enable/disable fullscreen mode)

Awesome!

 

[blaww]

I do load core, start core and get "failed to load content." Anything I'm missing?

 

[rock88]

"failed to load content."

Try to change video driver to gl or glcore and restart RetroArch (Moonlight-libretro used glcore driver and can switch to it from gl, but not from vulkan).

How do you enter a zero when adding host IP address?

 

[Empty02]

it loads endless, if i enter host ip

Seems I just forgot adding zero button, added in latest release.

You connect your Switch to the network? And this network is the same as on your PC?

Awesome.
Playing Sekiro on my Switch out in the garden lol.

Working great now, hardly any lag from what I can tell. I think I'm finally about to make some progress on my Steam library thanks to this

Edit- When I'm running emulators in fullscreen, pressing start puts me back in windowed mode, like it's acting as the ESC key. It's only for emulators like RPCS3, Dolphin and regular Windows programs though, no problems in actual PC games. I have this same problem with SkyNX as well

Works great! thanks you so much! There are some things that can be improves to be perfect,

- Colors look washes, blacks looks greys.
- Will be great if you can add a no skip frames option for perfect smooth 60fps.
- Greater bandwitch limit (why 30mb?)
- Rumble for joycon
- H.265 codec

sorry if I'm pedantic

I know very little about this so excuse my ignorance but do you have to have a Nvidia computer for this to work or any computer will work?

I'm also use rpcs3 in fullscreen mode and PLUS(start) key work properly, may be you has software for remap gamepad keys or you map start key on rpcs3 settings?

I'll check color transform, may be some wrong, but for me it's okay
Firstly I want to add some usage statistic (network latency, how much frames decode and drawn at second, etc), because I think has problem with sync frames from decoder and render.
No problem to increase limit, but for me, if I set value over 6-7Mbps, appear grey laggy frames, though I use 5Ghz Wi-Fi channel.
If RetroArch for Lakka Switch support rumble, I'll add it))
H265 currently supported, but may be needs setup a stream with some specific configs.

Nvidia GameStream software support only Nvidia GPU. I'm not sure, but may be with this software - https://github.com/loki-47-6F-64/sunshine you can run a stream on a non Nvidia GPU.

Steam was running in the background and was loading a controller profile. Everything's working great now, thanks for your work so far!

i’m gonna be all over this. sekiro worked really good but it’s mainly a solution to running dolphin for me

great job

New update here:

• Support H265 video codec (Change in Settings);
• Increase bitrate limit up to 150 Mbps;
• Fix incorrect color tranform;
• Add new shortcut for ESC key - L+R+Right.

Also I checked rumble - it doesn't work

Wow that was fast!

Awesome job man

My only concern is that it uses CPU video decoding instead of NVDEC.

To be honest, I'm not even sure that using NVDEC under Lakka is possible at all (at least at the moment).
I know that Moonlight on Android (switchroot) uses NVDEC though.

Maybe @natinusala could provide us a bit of info on that?

 

[rock88]

@mss1988, you are right, I checked - currently it's used software decoding I'll try to use hardware decoding over VDPAU, but no sure about NVDEC.

This is really cool. I set 720p/60 fps and 16.5 mb/s and got some bad blocking and flashes of grey screens. These were 100% fixed by raising CPU overclock to boost (1200ish). Games look and sound beautiful and input lag is truly minimal.

A little inconvenient launching lakka but the results are excellent. I hope one day it can come to horizon.

tried it games not opening at all, says:
"Cannot Configure Streamer."
