Hello I just discovered mopidy, I installed irid and YouTube extension. I was able tonplay a music from a local file, I can search for musics in the task bar it give sme YouTube results but when I play the youtube music nothings happens. Plus the pictures dont load even from the local music.How can I solve this please ?

If you’re using Mopidy-File, that doesn’t support album art yet. File: Implemented get_images for file library by parth-verma · Pull Request #1925 · mopidy/mopidy · GitHub

I don’t know about YouTube. What does the log from Mopidy say?
