VRCResolver

VRChat plays videos through yt-dlp. Stock yt-dlp is slow, breaks whenever YouTube changes something, and returns URLs that AVPro blocks in public worlds. VRCResolver replaces VRChat's Tools/yt-dlp.exe with a patched build that resolves videos through vrcresolver.com and serves them from a local address AVPro trusts. If anything fails, it falls back to VRChat's original yt-dlp. Playback is never worse than stock.

Formerly WKVRCProxy.

What you get

Streams come from localhost.youtube.com:{port}, which is on AVPro's trust list, and that's what makes them play in public worlds. Videos are resolved on the server instead of your PC. Regional blocks and rate limits on your connection don't apply, and the server updates its yt-dlp nightly. A new URL takes 2-3 seconds and a repeat about 20 ms. You get 1080p HLS instead of 360p mp4. Any failure hands the URL to VRChat's original yt-dlp.

It doesn't bypass DRM, host any content or log in to YouTube.

Install

1. Launch VRChat once. The patcher needs Tools/yt-dlp.exe to exist so it can back it up.
2. Download the latest vrcresolver-*.zip release and extract it anywhere except Program Files.
3. Run vrcresolver.exe and accept the one-time UAC prompt. It adds 127.0.0.1 localhost.youtube.com to your hosts file, which public-world playback needs.
4. Launch VRChat. When the console shows [mesh] connected, paste a video URL into any in-world player.

To update, type /update in the console.

To uninstall, run vrcresolver.Uninstaller.exe. It restores the original yt-dlp.exe, removes the hosts entry and deletes %LOCALAPPDATA%Low\vrcresolver\. It doesn't ask for confirmation.

Windows 10/11 x64. It's self-contained and there's no installer.

Troubleshooting

The console prints one line per resolve: green means resolved, yellow means it fell back to stock yt-dlp, red is an error. Full logs are in %LOCALAPPDATA%Low\vrcresolver\logs\. When you file a bug, include the correlation-ID block for the failed resolve.

How it works

VRChat (AVPro)
   v  paste URL
Tools/yt-dlp.exe        patched shim
   v  named pipe
vrcresolver.exe         watchdog
   v  WebSocket
vrcresolver.com         remote resolver

The resolved stream comes back through the watchdog's local listener at http://localhost.youtube.com:{port}/play/<session>/manifest.<ext>?target=.... If any link in that chain breaks, the shim runs the backed-up yt-dlp-og.exe instead.
