I have Nextcloud running locally in a Docker container, connected with a 100/10 mbps connection. A second server with STUN, Turn and High Performance Backend is located in a data center with a 1 GBit connection. All software is up to date. I installed the second server using this script.
When I use Talk to call a second user, the picture quality is poor in my opinion. It is miles away from the advertising photos on the Nextcloud website. Is there a way to improve the picture quality?
I have tested with various browsers (Safari, Chrome, latest version) as well as the desktop client for macOS and the app for iOS. I have set the video quality to “HD” in the app, but the picture looks more like VGA. On the Mac, I can see that the upload is just 150 kbps.
The poor picture quality is actually all that is stopping me from using Nextcloud Talk for communicating with customers. Posts regarding this issue in this forum are several years old. The documentation doesn’t give much information either, it mainly just shows the pattern Nextcloud uses to downgrade the image quality based on the number of participants. so I think it might be worth asking again.
