I have been working on a GUI for youtube-dl on Android for quite some time now. It works on my Samsung i9500 on CM13. I need your help in confirming that it works for other devices, especially 64bit devices.
I've uploaded it to the Play Store Beta program for easy feedback options. I cannot support YouTube in the Play Store because it's against their TOS. However, I'll share a plugin that will enable YouTube support for xda users.
You need both the app and plugin for youtube to work.
