Apparently Cingg then should supports NVENC
via some dynamic linked external Nvidia lib,
equivalent to what we did for for QSV via
oneVPL support.<br>
While h264_nvenc.mp4 rendering works,
h265_nvenc.mp4 fails with the following
errors, see detail below:<br>

Booted BIOS and checked that the integrated
Intel gpu and multimonitor setup were
enabled. <br>
Installed the suse-prime package for <font

gpu selection (for NVIDIA optimus laptops
with bbswitch support) and could then run
the command<br>
<br>
prime-select on-demand<br>

and verified that both the Intel and
Nvidia drivers were available<br>

Tried the other option MPEG, and also BT.709, which both
works for h264_nvenc, but has no effect with regards to

So far it looks for me that there is something wrong

<br>
Yeah, hevc_nvenc turns out to have just the same tff interlace issue
as we experienced with qsv.<br>
At first I just tried to change Cingg Setting | Fomat Video to "Not
interlaced" and the interlaced hdv file rendered OK.<br>
Tested also that a deinterlaced (progressive) version also rendered
ok.<br>
<br>
Loaded also a bff interlaced SD.dv file that Cingg Setting
recognized as "Unknown", did render ok without manual change.<br>
<br>
Maybe also h265_nvenc preset at opportunity also better should be
renamed to hevc_nvenc in accordance with ffmpeg's use.<br>
