 Summary of the bug:
 According to '''ffmpeg -h encoder=av1_nvenc''' -level goes from 0 - 24
 where 0 = 2 and 23 = 7.3.
 So I tried using 7.3 and the following error was shown
 [av1_nvenc @ 000002811fa86240] InitializeEncoder failed: invalid param
 (8): Unsupported Level.
 How to reproduce:
 % ffmpeg -f lavfi -i testsrc -c:v av1_nvenc -level 7.3 -pix_fmt yuv420p -f
 null -
 {{{
 BtbN > FFmpeg-Builds > ffmpeg-master-latest-win64-lgpl.zip >
 N-109120-g59b16355ec-20221117
 build on 17-11-2022
 }}}

 That command actually showed a second bug because '''ffmpeg -f lavfi -i
 testsrc''' outputs yuv444p (or at least the encoder pretends it does, it
 actually says RGB24) and '''ffmpeg -h encoder=av1_nvenc''' says it
 supports yuv444p and yuv444p16le but it then goes
 [av1_nvenc @ 00000176457a0c40] YUV444P not supported

 I tried using -pix_fmt yuv444p and yuv444p16le but it also errors. So to
 be consistent I went over all listed Supported pixel formats and the
 following don't work.

 yuv444p yuv444p16le gbrp gbrp16le (cuda d3d11 these are probably not
 supposed to be in there)

 Then lastly I have a question. Does this support the dual encoders from
 the 4000 series in any way? I can't seem to find information on it.
