The filter outputs hardware frames in d3d11 format; use hwdownload,format= if system memory frames are required. This would strongly alter my plans if I were to develop an OSS Discord alternative.

If you were doing this, consider cribbing from https://github.com/obsproject/obs-studio/tree/master/plugins... which offers a variety of solutions including some rather exciting looking process injection (called "game" there).
I wonder if "entire chat app functions as OBS plugin" would work? Would solve the AV streaming side of the functionality.

#14Earlier quoted context omitted.
TIL: JPEG XS - an image and video codec that offers both visually and mathematically lossless quality for low latency implementations. Additionally, JPEG XS compressed content is indistinguishable from the original uncompressed content. https://en.wikipedia.org/wiki/JPEG_XS
Isn't the point of JPEG to have lossy compression for your photos that still looks fine? As opposed to something like PNG, which has lossless compression
Reading that it looks like the point of JPEG-XS is to have near-lossless compression for raw photo and video data while having extremely high throughput.

The Joint Photographic Experts Group manages many standards, generally each called "JPEG [something]". The one we most commonly call "JPEG" is just one of them.

"JPEG" is short for Joint Photographic Experts Group, an ISO/ITU group that creates a lot of imaging standards. The JPEG image format you're thinking of is only one of the formats they've created.

#17How much of this release was done by to corporate/big tech employees?
Re: FFmpeg 8.1
#18I wouldn't get too excited about rockchip hw encoding. It's rkmpp based, not an upstream solution. You'd need Rockchip kernel for this, I guess.
It's still a big deal, you had to compile ffmpeg yourself before

I tend to build ffmpeg from source because package managers don't usually include support for patented codecs.
(Yes I know there are repos to get binaries for some, things like deb-multimedia.)
Re: FFmpeg 8.1
#20FFmpeg is really great. The only wish I'd have is for the usage to become simpler - both for regular stuff, but also for advanced filtering.
If anyone remembers, avisynth was pretty cool back in the days. You could kind of script video/audio manipulations, a bit like a UNIX/Linux pipe, but kind of simpler, in my opinion. FFmpeg allows for many similar operations, but remembering anything here is ... hard. I'd love for the whole usage API to become much simpler, but it seems nobody among the ffmpeg dev team is considering this. :(
I can't be the only one with that wish though ...
It does not diminish ffmpeg being so great in general, but I think it could be better.
