Another example, which i can personally verify has been working fine for months. It works a bit different to the above, it downloads the latests 2* vids that are not already downloaded and runs once every hour.

Channels i am “subscribed” too are stored in a single text file, it also uses the avc1 codec because i found p9 and p10 had issues with the jellyfin client on my tv

looks like this, i added categories but i don’t actually use them in the script besides putting them in a variable, lol. Vid-limit is how many of the latests vids it should look at to download. The original reason i implemented that is so i could selectively download a bulk of latests vids if i wanted to.
