The eventual solution for YouTube is to start injecting advertisements into the content packet stream, complete with re-keyframing and altering the metadata files to incorporate the ad segments into the run length. Everything prior to that is their increasingly-desperate attempts to not have to re-code their content streaming server to dynamically modify streams with advertising on the fly. But they won’t have to do that until video ad blockers start playing the ads invisibly in a shadow of the page, without showing them to the user at all. Which is pretty advanced for a regex-based player and not something I expect to see with last-gen ad blocking. Looking forward to it!
