Cloudstream uses it too: https://github.com/recloudstream/cloudstream/blob/master/app...

For local videos with GNOME Nautilus, there is https://gitlab.com/futo-org/fcast/-/tree/master/clients/naut...

Bruno maybe? (https://www.usebruno.com/ && https://github.com/usebruno/bruno)

Just downloaded Bruno and it looks great! Thanks very much.

I hope that someday we will be able to use VoLTE on a Samsung device with an Android OS like LineageOS, /e/OS, etc.
