<[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?
