That is prone to error, just a pixel can be too small of a sample. I would prefer something with hashes, just a sha1sum every 5 seconds of the current frame. It can be computed while buffering videos and wait until the ad is over to splice the correct region

The problem with (good) hashes is that when you change the input even slightly (maybe a different compression algorithm is used), the hash changes drastically
Yes, that’s why I’m proposing it as opposed to just one pixel to differentiate between ad and video. Youtube videos are already separated in sections, just add some metadata with a hash to every one.

Imagine thinking they can’t detect when you try to skip forward during an ad.
