Recently I performed a zypper dup and realized that ffmpeg no longer was supporting nvenc encoding. I verified that the nvidia drivers were still there and operating properly and they were which left me perplexed. I snapped back to before the update and everything was working.
I followed that up by just updating ffmpeg itself (upgraded to ffmpeg-5 5.1.4-1699.20) and once again nvenc was no longer there. After that I took a look at yeast and realized ffmpeg-7 was separate from ffmpeg-5. So I went ahead and installed ffmpeg-7 which deinstalled the -5 version and nvenc was available again. The version of ffmpeg-7 was 7.1-1699.3
I dont really have a question here but wanted to post this incase someone else finds themselves in a similar situation. Upgrading to a newer major version resolved the issue for me and I would suggest you try it to if you get into the same situation.
