because the average US based internet connection can fetch large images with no trouble, and only retards cater to the smallest common denominator.

Because 4chin never adopted WebP

At 40kb you would have a pretty decent looking 720p image.

that really isn't a good enough reason that justifies having leaky pipes because we can just keep pumping more water. same thing with balooning sizes of OSs when we are not using flash memory and paying for having ignored the storage size needed for some OSs.

>>54866374

Thats true. They're slow to load for me and others with similarly slow or shitty hardware. However, my computer has no issues playing some games that are way more resource intensive than a webpage, do you think it is reasonable that a webpage take longer to load and be slower to load than more resource intensive vidya?

That's not compression, that's just hotlinking from an external source.
It puts just as much load on the network as it would ordinarily, plus the load of downloading that image.

A real ``compression", that's similar in concept to what you are doing (but correct), would be to find the starting and ending index in Pi (or other irrational number) which contains the bit-string represented by the image.

>>54869598
the index would be larger than the file

>>54869210
slight improvement

>>54869598
chance of finding 1 bit in the 1st bit of pi - 1/2
1 bit in the 2nd bit - 1/2
etc..
chance of finding 1 bit at a given index - 1/2
expectation: 2 index long search
implication: ~1 bit index for 1 bit
chance of finding 2 bits in the 2 1st bits of pi - 1/4
chance of finding 2 bits in any given index... - 1/4
expectation: 4 index long search
implication: ~2 bit index for 2 bit
3 bits: 1/8
expectation: 8 tries
3 bit index.

it would seem that the expectation of index length is the same as the size of the data.

isn't that curious?
I suppose yes- it could be shorter. But 1/2 a chance of being shorter 1 bit, 1/4 by 2 bits, 1/8 by 3 bits etc...
The probability of making it any reasonable amount shorter is the same. The chance of making it longer is just as likely.

Someone has probably already solved this.

since pi is not a perfect enumeration (it contains repeating bits), your index/offset will be, on average, longer than the data itself. In practice, quite significantly so, making this utterly, ludicrously impractical for any real world purposes

>5 years from now noone will even remember it.
Movie industry is not giving up on it and it's getting more and more support on hardware encoding and decoding every year. It's not going anywhere yet but HEVC content distributed over internet is likely going to be much smaller than competitive open and royalty free codecs like VP9 and upcoming VP10. I'm guessing we'll be seeing HEVC being the standard codec for recording videos in cameras too but that'll left to be seen. It could also potentially be used widely for various kind of movie/anime encoding scenes.

You have to have a finished product to take off.
You can't get bpg through DNF or APT
You have the choice of compiling it yourself or going through some God awful web interface

But there's hope! Since all it needs is a little Javascript to display images and works in just about everything it's a perfect alternative to webp.

So in short, when Hiro tags a little extra JS to the site & lets us use BPG AND I don't have to compile anything I'll convert every fucking image I have. Until then keep pushing.

No camera manufacturer will pay for hevc when they can just stick a bigger sd card in their cameras. Movie industry maybe. The only people that are benefitting from HEVC currently are pirates.

Besides HEVC is going to get BTFOed march next near when the alliance for open media (Google, Mozilla Cisco, Intel, AMD, ARM, Nvidia, Microsoft, Netflix, Amazon) release their codec based on VP9, Dalaa and Thor..

AV1 or whatever the fuck it's called is DOA. It will have no HW decoding support or even SW support for a few years.

>>54876872
Yes, the codec designed by intel, arm, nvidia and AMD will definitely not get HW support the first year its out.

>>54863646
This philosophy is the recipe for bloat.

>>54876872
>or even SW support
Google, Mozilla and Microsoft are in on this. They will most likely add support for it very quickly to their browsers and services.
Hardware support might be lacking, that is true.

>>54885174
That's not a ``video", it's WebP. An image formatted using VP8/9 under the WebM container.

Images are the same as video. Only the compression method is different.
It simply turns out that traditional JPG and PNG compression are less efficient than VP8/9 compression.

>>54885174
still image compression. used for keyframes, look it up

>>54885215
