I'd be happy with surround (5.1) upon windows, alas it seems you can only get that via an Amazon device. HD 5.1 would suit me over any 4k and do feel many streaming services use the 4k etc as marketing more than anything else and fail upon the audio aspect in regards to surround, which IMHO add's way more to the viewing experience than a bump in resolution - though others millage may vary.

React and Flutter aren't immediate mode only because they're build on top of the DOM as primitive. Otherwise, conceptually they are evolutions of immediate mode. And they inspired plenty of GUIs outside the web to go "immediate" mode themselves.
Flutter isn't built on top of the DOM. And anyway that's not why they're not immediate mode. Take a look at some egui code and you'll see huge differences, e.g. in how button clicks are handled, when code runs, etc.
>Flutter isn't built on top of the DOM.
The web version has a DOM-based HTML Rendered in addition to a separate Canvas one. So (on the web, where the DOM is applicable anyway, it kinda is).
In any case, I didn't intend to go about Flutter, which I don't use, just wanted to write about React. I mentioned it while answering because the parent comment mentioned them together, and I didn't paid much attention.

I am interested in using video compression to improve delivery of VR and AR content over the web. But, this can mean a lot of different things! I know there is a lot of opportunity for this, I have a lot of ideas, but my knowledge of video compression and video streaming is limited. There are some companies working on this, but it’s not a singular problem or solution. I expect it will end up being many categories of…
It's all made of inter prediction + intra prediction + residual coding. There's an evolution from JPEG -> MPEG2 -> MPEG4 part 2 (XviD) -> AVC -> HEVC… where it gets more complicated over time but that's still the structure. There's also alternative ideas like wavelets (JPEG2000) and many other minor silly ideas; almost all of them are bad and can be ignored. Which is not to say the MPEG codecs are perfect. ML people…
All noted. I’ll look up the items I don’t know. Thanks.
And yeah, I didn’t mean blackbox like ML. I meant like H.264/H.265. Blackbox isn’t the right term.

DeCSS was considered a very big no no if you worked for a company that did work for content owners. Doom9 had lots of info on how to use DeCSS, and so it was flagged by lots of corps. Where would I start today? That depends on your level of interest, and what you want to do. Are you wanting to learn things to do to stay hip and cool making videos for the socials, or are you wanting to do technical things to video for…

There's a bunch of details that can be suggested, but the sad (actually, amazing) thing is that compression and encoding software has come such a long long way, that most of the default settings will produce a very decent result. FFMPEG + x264/x265 are stunning with minimum inputs required (minimum compared to the many many switches you can fiddle with individually).
For a broader understanding, look into the basics of how codecs like h.264/h.265 work. Learn about I frame encoding and how P and B frames work. Learn about the affects of long-GOP (multiple seconds) encodes for streaming purposes vs shorter GOPs (half second). Understand how an encoder makes it's vector decisions. How/why static videos encode compared to fast action. How will the videos you intend to use for VR/AR fall into those categories.
Resources like articles on Wikipedia have lots of information on the technical side of things without that are not video compression tutorials. However, learning the tech side will help make informed decisions on what knobs to tweak and why. There are so so many actual blogs/tutorials/SO answers/etc that will give you actual settings to apply. Once you have the specific question, I will be amazed if there is no answer available for it online.

Frontend engineering is a thing because of the accidental complexity of a massive software stack that's evolved by accretion and gone through fad after fad after fad. I'm not looking down on frontend engineers, but I don't believe right-to-left languages or focus order inevitably leads to hundreds of thousands of lines of code or 50+ MB binaries.
This comes off incredibly naive of FE engineering. Buttons and Doodads? sigh. A significant factor as to why Apple has succeeded the past 2 decades is due to the design of their products - from the sleek aluminum bodies of their hardware to the UI/UX of their operating systems. Unless you want your UI to look like something out of 1995, you're going to have to make it look good. Making it look good will require a dec…
I feel the conversation will just cycle if we try to push people to the poles of opinion and insult them. Accidental complexity is an enormous, pervasive problem across all software stacks. The ratio of lines of code to pixels on the screen is pretty bonkers. Since you mention Apple, if you look at the ratio of lines of code per pixel, it's really hard to understand how an OS weighs in at 10GB, even for Apple which is brazen about deprecating and only catering to their own hardware and products. That speaks to a universal bloat problem that shows no signs of slowing down. I mean we could dive down into the details and keep coming up with special pleading for every little functionality, but it won't be a productive conversation, really, and the big picture will be completely lost.

Just leave that part out next time. Anyone can write this at the end of any comment and it only injects a bad vibe into the whole conversation.

It's not just HDR content. I was watching a 2008 BBC drama called Little Dorrit on a Roku in 1080p streaming, no HDR because that didn't exist when it was filmed. It was super smeary, had terrible blacks, tons of obvious banding artifacts, it was really bad. I bought the 1080p Blu-Ray version from the UK, and even my parents standing 10 feet away from our 48" 1080p TV (without me explaining the problems with the Prim…
Could possibly be an issue with the HDMI Black Level setting on the Roku's input.
It was a Roku TV, so the Roku video signal was built-in and not passed over HDMI.

> There are working examples of such and the code appears to be significantly simpler than the status quo Status quo is bloated -> someone rewrites a simple replacement -> becomes popular -> "Can you cover this reasonable use case, it's not currently supported" -> repeated previous step several hundred times -> oh fuck, the "lightweight" rewrite has become the bloated status quo -> GOTO step one
In some sense, this is WAI. Hopefully along the cycle, people learn to build better architectures that are modular, scriptable, customizable, and not giant monolithic piles. If things were more scriptable, then I as a user could script them how I want creating of a wall of my own "UI" and then swapping out the backends as I see fit. In my 25 years or so programming, I wish I had done this more; scripts for everything. Learn how to use my own scripts and only adjust them when stuff breaks/is swapped out. In retrospect, I have been buffeted by the whims of UI designers for decades, and I'm kinda mad about it.

> It would take centuries for one single person to grasp what is going on in an iOS "Hello World" app. Not really. Several years, maybe.
I have been developing iOS apps since 2014, and was active in the jailbreaking scene before then. I don't believe any one person understands the entirety of what is going on when they launch an app. Remember, iOS is based on macOS, which is based on NeXTSTEP, last released in 1995!
iOS has been plagued by a whole host of bugs from the 90s and below. Remember effective Power? (https://apple.stackexchange.com/a/189064/364414) A Unicode memory allocation bug, the code for which was probably written decades ago and intended to run on a CRT monitor. I find it hard to believe anyone at Apple had interacted with that code since the initial iPhone release. Probably nobody at Apple in 2015 knew it existed. It's so unfathomably complicated.

For whom do they work for? The author and maybe a small group of Internet hobbyists? When you have to support 3 billion daily active users like iOS or Windows does, that lightweight codebase isn't so lightweight anymore.
And sure, Prime Video isn't Windows, but it still has over 200 million international subscribers that it needs to handle. It's definitely not something you can write in an afternoon.

As long as they don't take it as an excuse to reduce bitrates further. It's getting pretty bad these days with macro-blocking everywhere. This practice really took off when covid started. I actually cancelled Netflix because of it. Amazon is not as bad for macroblocks, but I have run into a few shows that show macroblocks, such as Mr. Robot.
>As long as they don't take it as an excuse to reduce bitrates further. I actually think it is easier ( comparatively speaking ) to push for improved Networking so someday bitrate becomes less of a concern. Just like what happened with Audio. Even with the state of the art VVC Encoder, you only get about 65% ( or 2.8x ) reduction in bitrate in most common cases compared to x264. 65% reduction in 20 years isn't exactl…
Lots of people have plenty of bandwidth. I certainly do. It's the service providers who refuse to send it. It's pretty pathetic, because if you obtain a 4k to 1080p re-encode from a third party, you will get a better picture quality than what the services send directly as 1080. They will not send a 4k bitrate stream to a lower resolution display, so it's necessary to patronize third parties.
It's only since covid that they latched onto the excuse propagated by idiots out there that the internet couldn't handle people watching video from home, and immediately jumped on it as an excuse to cut quality to save a penny. Executive bonuses all around. Clap clap.
