Do you plan to add encoding support via NVENC?

Originally I had planned to look into it, but I'm not so sure now. I don't know if hardware video encoding is useful for the very few programs that can actually make use of this library.

Sway/Nvidia user here. This is the only working solution for hardware accel for me. Sunshine comes to mind. Would be amazing to have NVENC.

Since Firefox can use the driver, would supporting encoding also open up hardware-accelerated encoding for screen sharing or sharing webcam video in conferencing solutions such as Jitsi / Microsoft Teams / Google Meet / ...?

It would also be useful for Virgl video encoding: https://www.phoronix.com/news/Virgl-Encode-H264-H265

Any news on this? I'll pitch in $50.

I did take a quick look at it. NVENC looks pretty straight forward to use, but I struggled to understand how to use VA-API to encode. From what I can tell, the mapping between the two isn't as straight forward as the decoding side is.

I also have a use for this, I use multiple different machines for hardware encoding, some of which have NVIDIA, others Intel and others again AMD GPUs, and having VA-API support on NVIDIA would drastically simplify the required ffmpeg command creation.

Waypipe could also benefit from this
