Stream switch games to your PC via USB or network

SysDVR

This is a sysmodule that allows capturing the running game output to a pc via USB or network connection.

Features

• Cross platform, can stream to Windows, Mac and Linux.
• Stream via USB or Wifi.
• Video quality is fixed to 720p @ 30fps with h264 compression, this is a hardware limit.
• Audio quality is fixed to 16bit PCM @ 48kHz stereo. Not compressed.
• Very low latency with an optimal setup, most games are playable !

Limitations

• Only works on games that have video recording enabled (aka you can long-press the capture button to save a video)
  • There is now a workaround to support most games, as it may cause issues it's hosted on a different repo and must be installed manually.
• Only captures game output. System UI, home menu and homebrews running as applet won't be captured.
• Stream quality depends heavily on the environment, bad usb wires or low wifi signal can affect it significantly.
• USB streaming is not available when docked
• Requires at least firmware 6.0.0

Clearly with these limitations this sysmodule doesn't fully replace a capture card.

Unfinished stuff

At some point I tried to implement a usb video class device via software, this would have allowed for usb streaming without needing a custom client app. Unfortunately this didn't work out, if you have more experience than me in this stuff feel free to give it a try, you can find more info in the readme of the UVC branch.
