This is a kernel plugin that uses lets you stream your PSVita screen to your computer via USB.

How does it work?

The plugin uses the SceUdcd module of the PSVita OS to setup the necessary USB descriptors to simulate and behave as an USB Video Class device (like a webcam or an USB video capture card).

The hardware color space converter of the PSVita's SoC is used to perform the conversion to the destination pixel format; then the USB controller directly performs a DMA transfer from the physical address of the resulting converted framebuffer, and therefore, saving CPU usage and power consumption.

Supported formats and resolutions

  • 960x544 @ 30 FPS and (less than) 60 FPS
  • 896x504 @ 30 FPS and (almost) 60 FPS
  • 864x488 @ 30 FPS and 60 FPS
  • 480x272 @ 30 FPS and 60 FPS

Installation:

  • Copy udcd_uvc.skprx to your PSVita
  • Add udcd_uvc.skprx to taiHEN's config (ur0:/tai/config.txt or ux0:/tai/config.txt):
*KERNEL
ur0:tai/udcd_uvc.skprx

 

  • Reboot your PSVita.

Troubleshooting
If the video looks glitched, try to change the video player configuration to use the NV12 format or switch to another player (like PotPlayer or OBS).

If you use Windows 10 you might have to change the Camera access permissions on the Privacy Settings.

On Linux I recommend using mplayer (mplayer tv:// -tv driver=v4l2:device=/dev/videoX:width=960:height=544).

Audio noise fix:

  • Disable USB power supply (Settings > System)

Note: Remember that if anything goes wrong (like PSVita not booting) you can always press L at boot to skip plugin loading.

Note 2: No, it doesn't stream audio. For that use a 3.5mm jack to jack adapter (a ferrite bead might help reduce the electromagnetic noise).
