why 2 times cuda on 'Supported hardware devices: cuda cuda d3d11va d3d11va' ?
Thanks!
Auto-Build 2022-08-17 12:47 by btbn and ffmpeg-5.1-essentials_build by gyan, I checked and they both said Supported hardware devices: cuda cuda d3d11va d3d11va. I think it's probably a bug.
what parameters are implied by -tune lossless?
Use-case
Preserving original video footage for later editing
General lossless data archiving (video or non-video)
