New blog: how FFmpeg uses Vulkan Compute shaders to accelerate professional codec workflows — FFv1, ProRes, ProRes RAW, APV and more — on any Vulkan-capable GPU, with no fixed-function hardware required.
Fully GPU-resident, no CPU hand-offs, and portable across the broad Vulkan device ecosystem.

Ever wondered how FFmpeg can use Vulkan Compute Shaders for video? Dive into accelerated encoding & decoding - #FFV1 included!
We’re integrating this feature in #RAWcooked, thanks to its sponsors for backing this tech journey.

finally back to editing the video, and I've now found that FFV1 mostly does not have hardware accelerated encode/decode on Linux yet (ffmpeg shipped major improvements last summer, but ffmpeg is not VLC or Kdenlive)
that's too bad, because it's a lot more space-efficient than HuffYUV, but if my (fairly ancient) laptop chokes on 1080p30 playback due to using the CPU exclusively, I can't use it.

Quote from the past (2016), regarding #ffv1 :
"You have open source and all, but the only reason you have no interoperability issues - is because **noone has interest in this format**"
If you're into watching high-profile public interviews like sports-games, you'll love this! #ffwewon 🥳 💾
-
btw: original specs said to use "J2K-lossless" encoding for VIP archival copies - but I've now heard it was later changed to #FFV1.
Tataaaa! 🥳
(A *broadcast* archive!)

...and there goes history! 💾
Quote: "**It is unlikely that a random hacker in Vienna would have the resources or expertise to develop such a standard on their own**"
🤣 🤣 🤣
#FFV1 - so cool, IA can't get its head around its story. -
#RAWcooked soon with a #FFV1 GPU-based encoder and decoder. Over the past few months, we’ve been collaborating on adding a GPU-based encoder and decoder for lossless #FFV1 video to #FFmpeg.

@juliacdelafuente @jandi
Still need any help with #linux and #audiovisual, #FFV1/MKV etc?The Fonoteca Chile has sponsored videos and subtitles on that topic, that I've put online:

@jandi Holi! Pues aún no me he puesto a ello. Esta semana empezaré a probar distribuciones de Linux. Cuando me haga un poco con el so empezaré a probar cosas!
Igualmente he visto que para codificar en #FFV1 MKV (que era lo q me interesaba) #handbrake ha hecho un preset de preservación (aunque el códec es ligeramente distinto al de #FFMPEG), y en #davinciresolve ya se puede exportar. La cosa es encontrar mediante pruebas qué le puede venir mejor al flujo de trabajo.
Iré informando!! 🐝

Avec l'équipe vidéo, on vient d'aboutir à une version validable de la fiche Format sur le codec #FFV1, utilisé par la BnF pour la numérisation de ses supports vidéo fragiles et anciens !
À défaut d'être une synthèse complète sur le format (d'autres organisations font ça mieux que nous), ça vous donne une idée de la compréhension que la #BnF a de ce format et, au moins, c'est en français.

Julia Colleen Miller on PARADISEC's journey transitioning to open source solutions for audiovisual processing incl. adoption of RO-crate, moving to S3, using AWS Lambda to run FFmpeg and adopting #FFV1/MKV as preservation primary.
Great presentation @spectregraph!

HandBrake now supports encoding to FFV1, the professional digital preservation video codec! All it took was a suggestion in a Github issue, and the maintainers were happy to include it. Now if some of you #digipres colleagues would test that it works as intended, that would be even better. https://github.com/HandBrake/HandBrake/releases/tag/1.8.0 #handbrake #ffv1

Quelque chose me dit que le RFC sur la version 4 de #FFV1 n'est pas près de sortir (six ans, déjà). https://datatracker.ietf.org/doc/draft-ietf-cellar-ffv1-v4/

A milestone in audiovisual preservation: the Library of Congress has recognized FFV1/MKV as a "Preferred Format"

Et voilà, encore une fois la France a fait le mauvais choix
MXF/JPEG2000, despite being used by prominent audiovisual archives like the French Institut National de l'Audiovisuel and the Library of Congress, suffered from significant drawbacks, including less efficient compression and issues with its Application Specifications (AS).

Ok, support for #FFV1 in #MXF for @GStreamer part 1 : The demuxing.
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3899
Turns out there was a type of sub-descriptors we weren't handling in mxf, so that was added too.
So that's what you get from #fosdem : someone does a presentation about something @GStreamer doesn't support yet, so I *have* to add it 🤣 -
