<[email protected]>:
To clarify some pieces once again, I put up some basic
statements or questions:
..........snip
So what happened when adding oneVPL (qsv) support to the
build system; dynamic linked to system or static added
embedded into the build?
dynamic
.....snip
Could in principle similar methods be extended to
include broader video acceleration support for AMD/amf
and NVIDIA/nvenc?
nvenc already supported, I think? At some point I tried it
with GF710 on livedvd and it was working for me. try to test
it if you have proprietary nvidia drivers.
Apparently Cingg then should supports NVENC via some dynamic
linked external Nvidia lib, equivalent to what we did for for QSV
via oneVPL support.
While h264_nvenc.mp4 rendering works, h265_nvenc.mp4 fails with
the following errors, see detail below:
[hevc_nvenc @ 0x7ff79c015640] No capable devices found
FFMPEG::open_encoder err: Generic error in an external library
Yes, seemingly:
Cin/bin/ffmpeg/video> ls *nvenc*
h264_nvenc.mp4 h264_nvenc.qt h265_nvenc.mp4
NVENC Presets
cat h264_nvenc.mp4
mp4 h264_nvenc
# encode for nvidia graphics hw only
preset medium
profile main
cat h265_nvenc.mp4
mp4 hevc_nvenc
# encode for nvidia graphics hw only
preset medium
profile main
Maybe I can do an attempt later, if I get life in the old GeForce
GTX 960 in my Skylake workstation.
Setup
----------
Booted BIOS and checked that the integrated Intel gpu and
multimonitor setup were enabled.
Installed the suse-prime package for nvidia/intel gpu selection
(for NVIDIA optimus laptops with bbswitch support) and could then
run the command
prime-select on-demand
and verified that both the Intel and Nvidia drivers were available
inxi -G

======
for hevc nvenc test may be try to set mjpeg colorspace instead of jpeg?
Tried the other option MPEG, and also BT.709, which both works for
h264_nvenc, but has no effect with regards to the hevc errors.
Tried also to comment out each and both of the h265_nvenc preset's
preset medium
profile main
but with no effect.
So far it looks for me that there is something wrong with Cingg's
hevc_nvenc encoding.

Did not render, neither with pixels yuv420p nor nv12:
