Changelog: - Extend AMF Color Converter (vf_vpp_amf) HDR capabilities - LCEVC track muxing support in MP4 muxer - Playdate video encoder and muxer - Add v360_vulkan filter - HE-AAC 960 decoding (DAB+) - transpose_cuda filter - Add AMF Frame Rate Converter (vf_frc_amf) filter - SMPTE 2094-50 metadata support and passthrough - ProRes RAW VideoToolbox hwaccel - APV Vulkan hwaccel - Animated WebP decoder - Animated WebP…

I'm curious if they used LLMs to do the tedious work of porting the (de/en)coders to different architectures, and how useful they are here.

In FFmpeg's twitter page it says that several of their developers got six free months of Claude Max 20x plan through Anthropic's Claude for Open Source Program, and that it was used, so far, to help find missing backports for this 9.0 release.

Seems like Yes. https://nitter.net/FFmpeg/status/2084084810813743614 "Thank you @ClaudeDevs and @AnthropicAI for supporting FFmpeg through the Claude for Open Source program!

So far, Claude has helped find missing backports for the upcoming 9.0 release."

Although i was under the impression that they ususally preferred hand optimized assembly. Not sure what their LLM/AI contribution policy looks like compared to other fundamental OSS projects.

Not a Lex Friedman fan, but I highly recommend the recent podcast he did with two leading engineers (and founder) from the ffmpeg project: https://www.youtube.com/watch?v=nepKKz-MzFM In a world full of endless AI slop, it is refreshing to see that there are still folks out there hand-rolling assembler code to squeeze out another 5% efficiency.

They used Claude for this release, as stated yesterday in their twitter page.

> - Animated WebP decoder Nice. browsers have supported this for a long time, and it was annoying ffmpeg did not, because that meant a lot of non-browser desktop apps couldn't view them either.

I've been waiting for this feature! Whenever I've encountered an animated WebP, I've had to drop it into ezgif.com to convert it to mp4, now I can just write a quick Bash function to transform it with ffmpeg.

I feel we’re blessed to have a project like FFmpeg. This open source tool is so important for everyone.

It's incredible how much it does, how quickly it does it, and how it just works every time. Whether I'm trying to deal with gigs of 4k video, embedding multiple subtitles into an mkv file, or just fiddling around with trimming a few seconds of audio off a wav, ffmpeg does it without skipping a beat.

Yes, to find missing backports. The hand rolled aspects are still there and haven't been replaced by slop.
