Changelog: * Radiance HDR image support * ddagrab (Desktop Duplication) video capture filter * ffmpeg -shortest_buf_duration option * ffmpeg now requires threading to be built * ffmpeg now runs every muxer in a separate thread * Add new mode to cropdetect filter to detect crop-area based on motion vectors and edges * VAAPI decoding and encoding for 10/12bit 422, 10/12bit 444 HEVC and VP9 * WBMP (Wireless Application…

This mostly looks like they're adding support for new codecs, there's only 4 new options in there, which seems rather paltry for a dot zero version release. Should we consider ffmpeg feature complete?

I am still using 4.2. Does it make any difference if all I care about is h264 and hevc?

Fabrice is superhuman for sure, but in 20 years the urban legend will go like ... Fabrice Bellard once read all of TAOCP in 20 minutes before being absorbed into his own AI and is now ascended in the ethereal ethernet silently fixing bugs in your code. Blessed be the bits.

Chuck Norris once opened Windows and created the Macintosh.

Chuck Norris once opened Windows and no bugs came in.

> Since FFmpeg is gpl2.1 I thought they had to make it easier to know they're using this Precisely, I doubt youtube just brazenly ignored this, but their legal might have buried it under some obscure link. I wonder if there's a license that require it to be "highly visible" in some sort of way.

Isn't it that they're not actually distributing FFmpeg, just using it themself, so they don't need to do anything?

Huh, I never really thought about it, but I guess that's one thing that GPL kinda fails at: if your server does all the work, you can leverage open source technology to do all sorts of stuff for your clients, so long as all the work the code you serve them does is collect and present data to the server.

Like, they get to see the code they run, but there's no insight to the code you run to deliver whatever service you're doing. Maybe this is obvious to other people lol, I just hadn't thought of it till now.

I wrote a large and messy script to encode a random amount of videos of any aspect ratio so it can fit in a mosaic with the xstack filter.

I think there are still slight audio sync issues, because I should reencode video files individually but I do a single pass instead to not deal with leftover files.

I'm quite happy with the result.

I wish I could write a script to do some basic effect on a video, like adding some moving text. The ideal would be to have an animated SVG file and make a video out of it.

Fun fact of the day: ffmpeg is written by Fabrice Bellard, who among other impressive things, wrote the JS PC emulator capable of running windows 2000 in a browser over 10 years ago that got me fascinated with emulators in general. https://bellard.org/jslinux/tech.html

Fabrice is superhuman for sure, but in 20 years the urban legend will go like ... Fabrice Bellard once read all of TAOCP in 20 minutes before being absorbed into his own AI and is now ascended in the ethereal ethernet silently fixing bugs in your code. Blessed be the bits.

Blessed be His bits.

Amen.

That’s very interesting. I assumed it was something about the fact that it is a language model rather than a calculating machine. So printing 44 asterisks instead of 40 is kind of close. I wonder if would it be possible to teach the machine to recognise situations it’s better at and be less confident other answers? Or does it need to be confident about everything in order to produce good answers where it does. It’s k…

We can check our answers, we can spit out bullshit like it does but then take the time to check them. It has no process for checking the answers or analyzing them and I'd rather not ask it how confident it is because that's just not what I care about. I find it amazing that it can actually sort of run code "in its head", all the code output it does is not actually run through an interpreter but it's still pretty clos…

I code with GitHub Copilot. I liken it to pair programming with an brilliant, insigntful & more experienced colleague who is always slightly drunk.

Yes, this is the reason AGPL was created. With AGPL software you have to open your changes, even if you don't distribute it and only use it serverside. There are still nuances, but this is the main gist.

If you want to know a bit more about what is important in this major release, you can watch my presentation about FFmpeg 6.0 at Fosdem: https://fosdem.org/2023/schedule/event/om_vlc/ (Video + Slides) It’s a bit less dry than the changelog, notably for the evolutions of the APIs. What’s also important is the changes about the release schedule that we’ve been pushing with the community. Major version every year at the…

So basically a chat routine that’s been designed to hit the Ballmer peak.
