I have a new stuff showing in my conky:

It's a status of downloads.

The script, autoytdl.sh, retrieve the new videos feed via YouTube API and check if there are new entries.

I use cron to run it every hour:

0 * *  * * autodlyt.sh livibetter /home/livibetter/Videos/ 1> /dev/null

The first argument is the account name, second is where to store data and videos. In my case, the downloaded videos go to ~/Videos/livibetter/videos.

If you run it for first time, it will download all videos listed in the feed. It's better to run it and interrupt it, then clean USERNAME/queue, that directory record what videos should be downloaded. It uses youtube-dl to download, one video at a time. So, the downloading process may take very long. If your cron run the script again when previous job isn't finished¹, well, same video could be downloaded twice.

This script could be very buggy.

(Normally, I wouldn't put such script into public. But YouTube homepage's Subscription section sometimes showed me videos I had watched through same section again, and YouTube often put be into 360p, or 480p if it thought my Internet speed is fast enough or I was just lucky. 720p, I always have to manually select.)
