Ahh, I get it now.
In the NVIDIA SDK, an NVENC session can be initialized via either a
shared CUDA context or DirectX.
Which reminds me: A while back, I ran into something similar with
VMWare's ESXi with NVIDIA's vGPU solution (GRID) based on the Tesla
T4.
Here is what I encountered and the workarounds I tried then:
I enabled TCC mode and rebooted:
nvidia-smi -g 0 -fdm 1
Then ran the command:
ffmpeg.exe -y -thread_queue_size 5120 -use_wallclock_as_timestamps 1
-fflags +genpts -loglevel debug -vsync 1 ^
-f gdigrab -draw_mouse 0 -framerate 60 -i desktop ^
-c:v h264_nvenc -profile:v high -rc:v cbr_ld_hq -r:v 60 -g:v 120 -b:v
8000k -minrate:v 8000k -maxrate:v 8000k -bufsize:v 8000k ^
-an -flush_packets 0 -bsf:v h264_mp4toannexb ^
-muxrate 16000k -pcr_period 20 -mpegts_flags +resend_headers
-mpegts_start_pid 0x15 -t 240 -f mpegts "lol.m2ts"
log:
C:\bin>ffmpeg.exe -y -thread_queue_size 5120
-use_wallclock_as_timestamps 1 -fflags +genpts -loglevel debug -vsync
1 ^
More? -f gdigrab -draw_mouse 0 -framerate 60 -i desktop ^

More? -an -flush_packets 0 -bsf:v h264_mp4toannexb ^

And ran into the same issue.
This limitation was overcome by switching to a larger vGPU config, so
I basically gave up on the case and never looked into it again.
With that in mind, perhaps you could try running the same but with
dxva hwaccel instead? Perhaps (and I could be wrong) switching to
dxva2 as a hwaccel should flip the device type for NVENC as DirectX
instead of CUDA.
That interop seems to be implemented, see
https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/nvenc.c#L52
See an example of such a command with your parameters:
