Change your port map and access it over https

well, tried that, and still getting "waiting for stream" after entering my user and password.

What browser you using clientside? try jpeg mode.
Also check the browser console for errors.
The browser must support webcodecs and it needs to use https.

[mekler22]

I have tested this on Chrome, Opera, and Firefox with the same result. I have tried x264enc, x264enc-striped, and jpeg. same result.

[thelamer]

You must be getting an error in the browser console no? Your server logs indicate the encoder is functioning and generating frames.

After changing the port mapping, did you recreate the container? Or just restart?

recreate. is there a special setting for nvidia gpus to work with krita docker?

[thelamer]

Dude you came here ignored the readme, ignored the changelog about https, proceeded to file an issue and now are asking about Nvidia support?

Let's stay on topic here, is it working now that you recreated it?

It started finally working when I started switching back and forth between the video encoders.
