So... MoQ represents a bit of a moving away from the all-in-one "black box" of web APIs like WebRTC. From the browser perspective, the main thing that matters is the WebTransport API. Using MoQT in conjunction with that WebTransport API, you now have various options for rendering the video as a player, for example: WebCodecs. But, if you can afford a bit more latency, you can also use APIs like MSE for playback and be able to use DRM.

And yeah, being able to publish from something like OBS is something I worked on before joining Cloudflare, but it depends a lot on what you do at the "streaming format" layer which is where all the media-aware details live. That layer is still evolving and developing with WARP being the leading spec so far. As that gels more, it'll make sense to bake things into OBS, etc. Already today though you can use Norsk (https://norsk.video/) to publish video using a rudimentary fMP4-based format similar to early versions of the WARP draft.

As for YouTube, Google has some folks who have been very active contributors to MoQT, but I'm not certain exactly how/where/when they plan to deploy it in products like YouTube.
