+NCDownloader has included both yt-dlp(faster version of youtube-dl) and aria2c and there is no need for manual installation under normal circumstances (*tested it successfully with snap version of nextcloud both in centos7 and ubuntu 20.04*)   
+But if for some reason,the builtin binaries don't work for you, then you will need to install them yourself

-local versions will be chosen over the builtin ones.
-But you can force the app use a specific version by setting the binary path manually. When the binary is valid, it has the highest priority and all other versions will be ignored
+Also, if you don't want to use the builtin versions, you can always force the app use a specific version by setting the binary path manually. In that case, the app will not try to find youtube-dl binary in your system, and the built-in ones will be ignored as well.
