youtube-dl for WD MyCloud Ultra EX2
From the README:
At one point I became so fed up with ads on youtube that I decided to not use the official youtube app on my smartphone and chromecast videos to my TV anymore. I already had a solution to watch videos on my phone without ads, but I also wanted to have the option to play them back on the TV - and also allow others to watch videos that way, much like multiple people can add videos to a playlist while chromecasting.
I already use a WD My Cloud EX2 Ultra and have Plex installed, so I was looking for an easy way to add videos without opening terminal applications or SFTP browsers. So I decided to build a very basic web frontend for the already famous youtube-dl and run it on the NAS.
