It's a very old API that was speced before promises were a thing. Once you ship an API, sites start using it, and if you change behavior, you break them. If your browser ships the behavior change first, and breaks a website, people just assume your browser is the one that's broken, and switch browser. So browsers don't like to change behavior, especially before other browsers have, or if other browsers won't.
At least in Firefox's case, it's hard to be confident that the decoders we use for H.264 (the most commonly used codec at the time) would support a given mime type.
Firefox uses the operating system's H.264 decoders, because we had a policy of not feeding the patent trolls. H.264 has a plethora of different levels, profiles and features [1]. The documentation for operating system's H.264 decoders often isn't very clear as to what profiles/levels/features they support. Sometimes the user has installed codec packs which affect what codecs are playable. Sometimes the user is on Windows K/N which ships without H.264 codecs. So the only way to give an accurate answer to the question, is to actually start up Windows Media Foundation, and run some video through them. This requires loading DLLs from disk, and obviously we don't want to be blocking on disk IO in the browser's JS event loop in order to accurately answer this question, and we might not have an example file for the specific combination of profile/level/features the script was asking about. In the end, we ended up doing a "test decode" on startup of the common profiles and caching the result in the user's profile. But again, if the user asks about an obscure profile or level combination we've not tried, we can't necessarily be confident that we'll actually be able to play this.
Saying "yes" optimistically and being wrong would be bad, as then the player would appear to be broken in your browser, leading users to switch browser. So the idea was script would try a few profile/level/feature combinations and pick the best to which the browser returned yes.
We probably could have done a more accurate job here if we had more time, but it's always a trade off between marginal benefits here, verses fixing something else.

I also tried using a mesh wifi network, and was able to bounce a signal around the dead zone and get a WiFi signal with a higher bandwidth than the powerline ethernet, but I still found I got a lot of glitches in video calls, so went back to the powerline ethernet.
I've not noticed the problems other commenters here had with their adapters with the AV2000.
I initially tried a cheaper powerline ethernet, and it was worse than WiFi, so I'd recommend you buy the most expensive/best one that you can afford.

Having the fullscreen request shift to the descendent video also breaks the case where you actually have an element containing a video that you want to make fullscreen, for example if you have custom controls for your video element... This is simply impossible with your API.
It's good because it shims the W3C specified fullscreen API; you only have to learn the specified API, you don't have to learn some other API.
Additionally there's the risk that the reviewer will reject the paper, and download the code and publish a paper about it quickly in some other journal/conference.
It's also confusing in that the number format follows a European convention of using decimal points rather than commas in between every three digits the numbers, though I can accept that localising your site isn't a big concern.
This has been discussed on the WebM blog:
"The WebM/VP8 hardware decoder implementation has already been licensed to over twenty partners and is proven in silicon. We expect the first commercial chips to integrate our VP8 decoder IP to be available in the first quarter of 2011."

"They don't address why they're removing it, why they chose to do it now, or whether or not they'll be consistent across their platforms."
Incidentally, months ago they've also blogged about why they'll keep YouTube using Flash, rather than HTML5: http://apiblog.youtube.com/2010/06/flash-and-html5-tag.html
Seoul is only 35 miles from the border with North Korea. The North has artillery which can hit Seoul, hence the South needs to be very careful not to provoke the North. Any engagement would be costly.
