I have an Acer Nitro model ANV15-51-51H9 which comes with an Nvidia GEFORCE RTX 4050. I believe this supports NVENC but whenever I try and get it to work in ErsatzTV the FFMPEG profiles only list QSV and VAAPI. I should also note I am using Ubuntu and not Windows or Mac. I am confused as I have OBS Studio and it is set to use NVENC and seems to work which makes no sense, either I have the capability or don't? This leads me to believe I must have somehow not configured it correctly in the set up. I REALLY love this software but it's eating my CPU almost fully when I run a channel, is there anyone here who could possibly assist me? Here is the output under the troubleshooting section. If more detail is needed please don't hesitate to ask! I really want to get this figured out.
