Stereo 3D encoding with nvenc

Etienne Sandré-Chardonnal
Hi,

Are there options for encoding 3D video with nvenc, like with x264 and
--frame-packing? I know the NVEnc API has the option, but was it enabled in
ffmpeg? I can't find any documented option.

Thanks!

On the hardware side, VAAPI (and possibly QuickSync) have such an option
exposed via FFmpeg. There was patchwork (not sure if it's merged or not,
it's been a while) authored by Mark? Thompson (sic, not sure, need to
confirm) enabling such functionality. Let me check on that and get back to
you.

I found the patch series, not sure if it was applied for VAAPI back in the
day. It was authored by Mark Thompson at the request of a user who was
dealing with stereoscopic H/W decode issues
