nah, they were already not paying licensing fees for PNG or JPEG the use case is it is 2010 and you are Google or Facebook and your largest growth market are cell phone users in India and PNG and JPEG just aren't good enough anymore and you have the resources to build the automated tooling to ingest images in any format and transcode them to the formats your app can display you stealing images from web sites and failing to open them in your pirated copy of photoshop wasn't a design goal

there are a bunch of different formats (HEIC, BPG, HEIF, …) based off of HEVC but that makes them pretty complex to encode and decode. they are all pretty similar and despite some pretty minor differences are for the most part better than webp i'd say jpeg xl is probably the best successor to jpeg and png but lol google got mad and ripped support for it out of chromium a few months ago. meanwhile apple just added support for it in ios 17 and sonoma

basing a still image format off of intra frame encoding of whatever the latest ITU or MPEG standard is really isn't a terrible idea but HEVC is already outdated, VVC/H.266 is the new hotness. keeping up with their developments would continue to be a problem as would the related increase in complexity. then there's the licensing issues JPEG-XL is already better at compressing still images than webp, HEIC or even AVIF though, and afaik it's royalty free

Shame Boy posted:someone should adopt jpeg 2000, as a joke fun fact: almost everything supports jp2 but almost nobody uses it for still images. but it's a video codec too and i've mainly come across it used for that since it compresses pretty well, encodes/decodes pretty quickly and supports an alpha channel. it's an under-appreciated format imo e: it also uses the mp4 container, so if something supports h.264 or even mpeg-4 ASP it's not terribly difficult to support jp2 also Beeftweeter fucked around with this message at 18:08 on Nov 8, 2023 |

qoi indeed seems cool but metadata and stuff like colorspaces matter. they are also not that hard to do on the format level, but too boring i guess.

the most infuriating thing about .webp is everybody who has apparently decided to switch to a bleeding-edge google format without bothering to provide fallback to image formats that have been supported everywhere for two decades at this point like .jpeg, .png, and .gif

also jxl doesn't need hardware support to exceed the performance of AVIF, HEIC or webp. that's kind of the point and it was just released in 2021. of course not much supports it. but chromium did, and then it suddenly didn't

I think Google likes stuff like webp because they're hyper focused on the needs of companies like Google where when you're serving a billion copies of something it's worth generating a bunch of different formats of everything and choosing the smallest supported one for each client I doubt it's actually worth the effort to do that for most people

pseudorandom name posted:what phones/tablets or monitors supported HDR in 2010? TVs didn't start getting HDR specs until 2014, and PC monitor HDR support has consistently lagged behind TVs. there weren't really specs for what we call HDR today back then, but that doesn't mean there wasn't support for it in hardware or software. qirex's post is a good example, qirex posted:I was doing 32 bit color for print on a 132 mhz computer in 1998 CRTs certainly supported 32-bit color, even back then (and way before). around 2010 finding a pro level LCD monitor with a 24- or 16-bit panel wasn't that hard. even extremely cheap ones were 14- or 12-bit, claimed to be 16-bit and just dithered it down. i mean, finding an explicitly 8-bit panel would probably have been more difficult than finding one with a higher color depth like for example the iphone 3g, released in 2008, had an 18-bit panel
