[Linux/CachyOS] WebRTC disabled in build — HTTP 503 when starting browser streaming

I'm running Vibepollo on CachyOS and attempting to stream my desktop directly through a web browser using WebRTC.

The Vibepollo web interface is accessible, and the streaming host starts successfully. However, starting a WebRTC session consistently returns HTTP 503.

Error

Connection Failed
Failed to create WebRTC session (HTTP 503):
{"error":"WebRTC support is disabled in this build"}

Environment

• OS: CachyOS
• Desktop: KDE Plasma
• Vibepollo: 2.0.1
• Installation: Native Linux package
• Web interface: HTTPS, port 47990
• Hardware acceleration: VAAPI

Relevant logs

Active: active (running)
Status: "Vibepollo generation 2 is listening with H.264, HEVC encoders"

Found H.264 encoder: h264_vaapi [vaapi]
Found HEVC encoder: hevc_vaapi [vaapi]

Steps to reproduce

1. Start Vibepollo on CachyOS.
2. Open the web interface on port 47990.
3. Navigate to browser/WebRTC streaming.
4. Attempt to stream the desktop.
5. Receive HTTP 503.

Expected behavior

Desktop streaming works directly in a supported web browser using WebRTC and hardware-accelerated video encoding.

Actual behavior

The server refuses to create the WebRTC session because support is disabled in the installed build.

Questions

• Is WebRTC intentionally disabled in the official Linux/CachyOS packages?
• Is there a build option or package variant that enables WebRTC?
• Is browser-based streaming planned for an upcoming Linux release?

Also, is clipboard functionality supported on this?

Thanks!
