This is something sort of a personal list of desktop software that I find most appealing to me from a certain standpoint I described in the name of the list. This list mostly contains apps made with Linux/Unix-like systems in mind, but I don't plan to include stuff that rely on specific desktop environments and distros, so apps from this list are mostly multi-platform. Warning - this list contains command line-based apps and tools that not every person can find use for
Versatile media player supporting multiple video formats, wide codec range, subtitles, hardware acceleration, OpenGL output, and intuitive CLI controls.

Part of my MPV description I moved it here:
You can watch online video from links with MPV, but if you want to use it to play Youtube videos I recommend installing yt-dlp (see in Downloaders) and: For Linux - create file at ~/.config/mpv/mpv.conf , then add script-opts=ytdl_hook-ytdl_path=/bin/yt-dlp to it, replace end of the line after "=" to your yt-dlp installation path if needed) For Windows - rename "yt-dlp.exe" to "youtube-dl.exe" and put it in mpv folder This will replace built-in Youtube-dl, which will allow to bypass throttling
