YouTube is currently experimenting with server-side ad injection. This means that the ad is being added directly into the video stream.
This breaks sponsorblock since now all timestamps are offset by the ad times.
For now, I set up the server to detect when someone is submitting from a browser with this happening and rejecting the submission to prevent the database from getting filled with incorrect submissions.
That would be cool.
I guess my AMD Bulldozer TV PC is gonna have to go in the ewaste bin though. Its already stretched to its limit running Linux Mint, Firefox, uBlock Origin and Sponsorblock as it is
