Frame-accurate ads over web video: today's method and the new one

Upload a game clip with the TGI augmentation packages for it; the server prepares it and streams it as live HLS, played with hls.js like production. One game streams at a time, and everyone watching sees that one. What to upload: the video (59.94 or 60 fps, any container), the 2-second .zip packages that cover it (select them all at once), and optionally PNG creatives (otherwise the example's are used). Both methods can be watched side by side because they play the same stream.
