Can you give an example of a player/feature combo where this is the case? For general player features there's not really an excuse for only working in one browser, but features like Casting can be browser dependent because the browser has to expose that functionality. Other interesting prototypes rely on a new API called Web Codecs that isn't fully supported everywhere.

In the core JS of Video.js v10 we're building without the assumption of there even being a browser involved so we can point to future JS-based platforms like React Native.

There have been other video players that attempt to be more "professional" adding things like audio meters and other tools. These are using parts of JS that is not available anywhere except in Chrome. After digging in, there's a lot of audio related things that Chrome is trying to do that FF/Safari are not. We have mp4 files with multiple audio streams that Chrome exposes ability to select from while FF/Safari do not. Creating waveforms on the fly from a video source also becomes problematic.

We've also had issues getting frame accuracy when navigating the video stream. There's some sort of "security" that randomizes/rounds the returned value of currentTime that I cannot wrap my head around as how that is security related. Lots of effort spent on getting stock HTML5 video element to be frame accurate.

Core contributor here! FYI these kinds of cases are definitely on my mind. One of the nice things about our overarching architecture is we (or someone else, even you!) can add/extend for these kinds in a way that doesn't deeply "bake them in" to core use cases but still makes it completely possible to add. From "soup to nuts" (to extend my food metaphors), we've built VJS in a "highly composable" manner, which means we can, say, add state features, add UI for those state features, extend media renderers to expose those features to the state (if/when needed), etc. etc. If you want to start a discussion picking a concrete Chrome-only API, I'd encourage it (https://github.com/videojs/v10/discussions).

I don't know if/when we'll prioritize these things as part of the "core library", given our higher priorities of "feature parity" and core functionality, but we're already well situated for these kinds of cases (I'm sure we'll encounter and need to figure out some wrinkles along the way, but I'm confident these will generally be tractable).
