I can report that endstream.sh launches and plays with no GUI in GNU/Linux. Tested in tmux in the shell with no desktop or GUI, on Debian 11. I wasn't aware that this was possible until recently. Sound and full motion video work. Good news for people who don't use desktops, xorg or wayland or any GUI. mpv can play videos in the command line with no GUI, interesting development.

I did some updates to endstream_bsd.sh, endstream.sh and winstream.bat, including adding some streams from cozy.tv. Available in the usual places:
