VRCVideoCacher is a tool used to cache VRChat videos to your local disk and/or fix YouTube videos from failing to load.
It replaces VRChats yt-dlp.exe with our own stub yt-dlp, this gets replaced on application startup and is restored on exit.
Auto install missing codecs: VP9 | AV1 | AC-3
From VRC or EAC? no.
From YouTube/Google? maybe, we strongly recommend you use an alternative Google account if possible.
In order to fix YouTube videos failing to load, you'll need to install our Chrome extension from here or Firefox from here, more info here. Visit YouTube.com while signed in, at least once while VRCVideoCacher is running, after VRCVideoCacher has obtained your cookies you can safely uninstall the extension, although be aware that if you visit YouTube again with the same browser while the account is still logged in, YouTube will refresh you cookies invalidating the cookies stored in VRCVideoCacher. To circumvent this I recommended deleting your YouTube cookies from your browser after VRCVideoCacher has obtained them, or if you're using your main YouTube account leave the extension installed, or maybe even use an entirely separate web browser from your main one to keep things simple.
Loading failed. File not found, codec not supported, video resolution too high or insufficient system resources.
Sync system time, Open Windows Settings -> Time & Language -> Date & Time, under "Additional settings" click "Sync now"
Edit Config.json and set ytdlDelay to something like 10 seconds.
Attempted to play an untrusted URL (Domain: localhost) that is not allowlisted for public instances.
Run notepad as Admin then browse to C:\Windows\System32\drivers\etc\hosts add this new line 127.0.0.1 localhost.youtube.com to the bottom of the file, edit Config.json and set ytdlWebServerURL to http://localhost.youtube.com:9696
