So, I installed the YouTube add-on and got it set up and everything.
At first most videos would play fine, while some would simply load upon selection and then nothing.
Today, no videos will play anymore. Either they load for a while and then nothing or an error “failed to play item, check log file” is displayed.
Just tried those options, but nothing has changed.
The alpha version still has the same issues as the older version. Tried clearing all the other caches as well, but didn’t help either.
I’m sorry to hear that I hope someone else can help you! In most cases issues appear when youtube changes something in their back-end and those issues are fixed by the developer updating his addon.
I already had the settings like in that post. So I went backwards through that thread and started with manual stream selection, lower resolution and all. It worked at 144p just like for you. Then I bit by bit upped the settings like you until I arrived at the max and your last post.
Now I have exactly the same settings as the ones I started with that didn’t work, only now everything works.
