Well, you're not alone. I just compiled 4.1-1255 and I see the nvenc options in the Stream Profiles -> Video codec preset dropdown. I tried to use the nvenc options but the video encoder just gave up and only audio was enabled on the transport stream. Here's some debug...

RE: Nvidias NVENC - Added by Stephan Oelze almost 9 years ago

@Prof Yaffle

its done through by:
https://tvheadend.org/issues/3438

its just possible now to build a statis ffmpeg with NVENC support as
ffmpeg is supporting this out of the box since 06.2015
https://ffmpeg.org/pipermail/ffmpeg-cvslog/2015-June/090257.html

Anyway, it dosent work for me. i am going to provide traced log soon.

Yes, that's the same thing - I linked the commit that addressed that issue. If there's still a problem, grab a log and/or post a new issue. I haven't tried building with this option as I don't have any (realistic) systems with NVidia chippery.

RE: Nvidias NVENC - Added by Stephan Oelze almost 9 years ago

Here is the trace attached. Normal software encode and a try to use NVENC.
I setup NVENC un my ubuntu 14.04.3 Server on a sepparated fresh install.
There is an ready build .deb for my distro from nvidia i used:

RE: Nvidias NVENC - Added by Hafeez Ahmad almost 9 years ago

I was struggling with the same issue and was able to compile ffmpeg with nvenc myself but somehow ffmpeg as part of tvheadend kept compiling without nvenc.

I configured tvheadend with:
./configure --build=x86_64-linux-gnu --prefix=/usr --includedir=${prefix}/include --mandir=${prefix}/share/man --infodir=${prefix}/share/info --sysconfdir=/etc --localstatedir=/var --libexecdir=${prefix}/lib/tvheadend --disable-maintainer-mode --disable-dependency-tracking --enable-libffmpeg_static --enable-hdhomerun_static --enable-dvbcsa --enable-bundle --arch=x86_64 --enable-nvenc

It showed nvenc was enabled but ffmpeg kept compiling without nvenc because it missed the option: --enable-nonfree --enable-nvenc
setting "EXTRAARG += --enable-nvenc --enable-nonfree" from Makefile.ffmpeg doesn't seem to get enabled, only "ENCODERS += nvenc_h264 nvenc_hevc" is enabled.

I fixed this by adding in the last FFMPEG section in Makefile.ffmpeg: $(EXTRAARG) \:
...
--prefix=/ffmpeg \
$(EXTRAARG) \
--disable-all \
...

After a make & make install you will get new options nvenc_h264 & nvenc_hevc in the tvheadend stream profiles for Video codec.
You need to choose this one for nvenc.

Log will show nvenc is used:
Feb 6 15:41:37 ubuntu tvheadend: transcode: 001D: 1:MPEG2VIDEO 720x576 > H264 720x576 (nvenc_h264)
Feb 6 15:41:37 ubuntu tvheadend: transcode: 001D: 2:MPEG2AUDIO > AAC (aac)
Feb 6 15:41:38 ubuntu tvheadend: transcode: 001D: Using preset hq

I can now transcode 2 streams at once with my passive cooled GT720 :)

Maybe someone who has knowledge of coding can fix this in the source code.

RE: Nvidias NVENC - Added by David Mainem over 8 years ago

Just out of curiosity. I am using Ubuntu 16.04 Beta right now.
From what i have read i must have the Cuda SDK and the Nvidia driver min. Version 352 installed.

Both things are in the Xenial Repos, could it be so easy to install both and recompile a recent TVHeadend 4.1 to work?

RE: Nvidias NVENC - Added by Henry Madsen Jensen over 8 years ago

Hi I cant get TVH to configure using switch --enable-nvenc, I just get an error.

checking for cc nvEncodeAPI.h ...                 fail
ERROR: NVENC library (https://developer.nvidia.com/nvidia-video-codec-sdk) not found

Have tried to install nvidia driver + CUDA SDK, can someone make a step by step guide to how and what i need to install to make it work

RE: Nvidias NVENC - Added by Acid Rain over 7 years ago

Something new?
It is working now out of the box?
(with TvHeadEnd autobuild script?)
I'm thinking about to buy me a passive GTX Card, to get a bit less CPU usage on my DELL PowerEdge T20
