I think you're out of luck in that case, looks like service workers can't be specified inline. I guess that makes sense from a security POV - prevents third party js from injecting a service worker to man-in-the-middle all your network traffic.

Back on the bug, there's a demo page here that shows videos with data uris for the source:
https://iandevlin.com/html5/data-uri/video.php

Using a blob via an object URL seems to have similar performance to me.

One weird finding, switching to an <img> tag with the mp4 as src ( as described in https://developer.apple.com/documentation/webkit/delivering_video_content_for_safari ) appears to give much better performance, and that would work inline. Downside is no audio, it loops, and there's no controls / timeline or anything. Depending on your use case it might be helpful though...
