VLC not streaming to chromecast

Help
1

Hey guys, any idea why VLC is not been able to stream to chromecast?
The chromecast becomes black and I can see just the movie tittle (años then title disappear).

Here my nixos config: my-nix-os/configuration.nix at 225188ead8c255167fd395a3ec20ea1960d5e31a · wllianwd/my-nix-os · GitHub

Here the logs:

Hey @rofrol , I was able to get rid of this error by adding a “VDPAU_DRIVER=radeonsi”.
Anyway the issue is still the same, when start streaming the chromecast seems to receive but screen remains black.

Maybe someone else will help. I still haven’t set nvidia prime correctly.

Hey sorry, so I just figured out the issue was just the firewall for port 8010 used by VLC for stream.

networking.firewall.allowedTCPPorts = [ 8010 ];

That fixed the issue.

Other errors that are in the above log seems that does not affect the stream.
