Well, there are different approaches to video splitting for encoding purposes, so here's some that hopefully may help in its implementation (random order): - @ValentinMastro's [AV1_SPLIT_ENCODE](https://github.com/ValentinMastro/av1_split_encode): _"First, we run the...

Just found this interesting git by @MartinEesmaa that *may* help: https://github.com/MartinEesmaa/VVCEasy

OK, we "discovered" that oneVPL lib is shipped with latest 4-5 graphics drivers updates (at least in my HD Graphics 630) on Windows. As already claimed [here](https://github.com/staxrip/staxrip/issues/822#issuecomment-1079939266) some Handbrake dev...

I know DVD Flick, but this is FFMPEG-based DVD encoding script... ...anyway, even if it's not interesting for FF, thanks for the reply.

OK, here are the [tebasuna51](http://forum.doom9.org/member.php?u=71585)' suggestions about (proper) multichannel audio downmixing with FFMPEG: >1) If your input is 7.1, first do a 7.1 -> 5.1 downmix with the compand selected...

It would be extremely interesting (and almost unique) to implement a "replaygain-based" normalization. Some interesting resources: https://github.com/Moonbase59/loudgain (python) https://github.com/kepstin/regainer https://github.com/chaudum/rgain3 Hope that inspires !
