This is a homebrew that enables streaming of PC games to the Nintendo Switch.

This was submitted to the GBAtemp Switch Homebrew Bounty 2018 (Switch application).

Note: This project is not maintained right now. It might be revived in the future but for now check out SkyNX.

Features

Stream PC screen to a Nintendo Switch in your local network.
- 720p (full Switch-Tablet display resolution).
- 40-60 FPS (if not see Troubleshooting).
- Low delay (again, see Troubleshooting).
- Audio support (experimental).
Capture controller input on Nintendo Switch.
- Emulate an Xbox controller on the PC.
PC app offers picture quality adjustments.

User guide

How to use

Install Scp drivers on the PC. For audio, Screen Capture Recorder also needs to be installed.
Download the release from here and unpack the zip where ever you want it.
Copy and run the NRO from the Switch-folder to your Switches SD-Card.
Run the "In-Home-Switching.exe" from the "Windows"-folder on your PC and enter the IP-Address of your Switch (can be found in network-settings).
Click on the big "Connect"-Button.

Notes:

In order to help performance we overclock the Switch. (disabled by default in 0.2).
Also please set your PC resolution to 1280x720p in Windows for getting much better performance of screen capturing while running the app.

Troubleshooting

Nice videos, but sadly that delay makes it unplayable.

If you are experiencing delays greater than 0.1 seconds, either your PC is just too slow for your chosen quality options (try worsening image quality) or your local network is bad.

Basically we need instant data transfer in your network to work properly (this has nothing to do with throughput, just latency). Some WiFi-routers unfortunately just aren't up to the task.

These framedrops hurt my eyes!

Your PC is probably too slow for encoding with the games/applications on.

Try other applications, lower image quality and, if you haven't already, set your PC screen resolution to 1280x720p (saves scaling).

No drops, but my framerate is just very low.

Well, in our tests we had 60 FPS on Windows 10 with low image quality... I guess you can try the same strategies as for fixing framedrops, I hope that helps.

Known issues

Sound far from perfect, delay not that great either (both issues will be fixed soon hopefully).
Sound sometimes weird in docked mode.
PC app sometimes doesn't show connection status correctly.
Sometimes processess are left over. If you encounter any issues please manually kill all ffmpeg.exe processes.
For some setups the audio is completely messed up, we're investigating that.
