The exact correspondence between the VPx-es and the MPEG codecs is not that relevant, because old codecs don't go away when new ones come out. In fact, hardware decoders are irrevocably baked into devices where consumption happens, so

libvpx, the VP9 encoder library used in this test, has no support for any hardware encoder blocks for VP9 [1], so it does everything in software. There are ways [2] to compile some support into ffmpeg-with-libvpx that makes it able to invok

Let that sink in: 'Encoding run time was 9226.4x, 8139.2x and 667.1x greater, respectively…' The codec is good, but the encoder has a long way to go. This places it squarely in the realm of only worth it right now if you're s

Onthologies are hard. Curation is harder. People are lazy. The ideas are still around; some [1] were lifted by Facebook [2], for example. There's also continuation work that's related, like web annotations [3], but generally the c

To my eyes and preference, both x265 and AV1's stills are far less blocky and far too smoothed than I'd like, but then again I've been an unabashed proponent of less smoothing [1], having lived through early H.264 encoders&#x

HEIF is the name of the container [1][2]. HEIC is an ISOBMFF 'brand' to be used inside the container to indicate that the payload's codec is HEVC (in 'Main' profile or 'Main Still Picture' profile), and th

This is a format combining HEIF as the container with AV1 I-frames as the payload. HEIF is the Nokia-developed, MPEG and ISO-blessed container for image sequences and transforms, which is published as MPEG-H Part 12, and is based on the goo

~1993 is around when CompuServe and Unisys began negotiating about the implications of patented LZW in GIF files, but the issue didn't become public until 1994, but the community rebounded spectacularly by developing PNG in 1995. So pe

It seemed to me like they meant the question politically, not technically, as in, would AOMedia have been possible? I think it's widely understood that the technical innovations in sixth-generation codecs like AV1 were simply not compu

Hey look, client certs! The primary innovation here is browser buy-in, and API hooks for onboarding to make the UI/UX of the process suck less. This is a good thing.

While none of this is false, it's a bit of a misdirection to imply that the 'mighty MPEG' was a monolithic actor preventing this course of action from taking place. In fact, the individual collaborators that MPEG (or ITU) bro

Typically it's a dedicated hardware block on the die of a larger chip, like AMD's UVD [1] and VCE [2] inside their GPU/APUs, or Nvidia's PureVideo [3] and NVENC [4]. Sometimes the line is even blurrier, like the Broadcom

Firebase is their Mobile-Backend-as-a-Service brand. The product they're driving customers to, Firebase Dynamic Links, is not really a web URL shortener, but more of a bridge between URLs and in-app links. In this light, it makes sense
