It seems like the NPO/uitzendinggemist website has changed in someway, which make their video's undownloadable with youtube-dl. Given the error output, it seems like it has something with new DRM protection. Interestingly, using streamlink + mpv still allows me to watch NPO urls.

@dstftw What is this a duplicate of? This behavior was introduced fairly recently (last week or so) and I didn't find any other mention of it.

Somewhere between version 2018.02.04 and 2018.02.26 this regression was introduced. I know this because I have an older version of youtube-dl on another machine. It works fine when using that version. @rien333, if you want it to work you can downgrade to 2018.02.04.

sudo pip install youtube-dl==2018.02.04

@dstftw, I suppose a fix is in the pipeline.
