use system ffmpeg // vaapi support

hi,
so I want to use tvheadend with vaapi support on ubuntu 20.04.1. Ubuntu is running on ESXi VMware 7.0.
I got vaapi working and i can use it with ffmpeg. intel_gpu_top shows me, the system is using the intel gpu for transcoding with ffmpeg.

error: XDG_RUNTIME_DIR not set in the environment.
error: can't connect to X server!

ERROR: vaapi requested but not found

Is there a way to tell tvheadend autobuild to use the system ffmpeg?
or how can i adjust autobuild just to use the variables i want to use?

I did try the following and this was working.

cd /tmp/tvheadend/build.linux/ffmpeg/ffmpeg-4.1.5
FFMPEG_PREFIX=/tmp/tvheadend/build.linux/ffmpeg/build/ffmpeg PKG_CONFIG=/tmp/tvheadend/support/pkg-config.ffmpeg ./configure --prefix=/ffmpeg --enable-shared --enable-vaapi --enable-gpl --enable-libx264 --enable-libx265

thanks

RE: use system ffmpeg // vaapi support - Added by Hans Müller over 5 years ago

For anyone using Ubuntu 20 and need to use python2 as well, here is how it's working.

$ sudo apt install python2
OR
$ sudo apt install python-minimal

check which python versions you have available

$ ls /usr/bin/python*
/usr/bin/python2  /usr/bin/python2.7  /usr/bin/python3

set the python alternatives

$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 1
$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 2

choose python version you want to use

$ sudo update-alternatives --config python
There are 2 choices for the alternative python (providing /usr/bin/python).

  Selection    Path              Priority   Status
------------------------------------------------------------
* 0            /usr/bin/python3   2         auto mode
  1            /usr/bin/python2   1         manual mode
  2            /usr/bin/python3   2         manual mode

Press  to keep the current choice[*], or type selection number: 1

python now working, still stuck at the same point. pretty sure it is directly related to ffmpeg.

RE: use system ffmpeg // vaapi support - Added by saen acro over 5 years ago

in folder where git clone

make distclean
./Autobuild.sh -j$(nproc)

or use auto script
https://tvheadend.org/boards/4/topics/24116#Automated-build-script

with will generate build.log

RE: use system ffmpeg // vaapi support - Added by Hans Müller over 5 years ago

still same problem.
attached the build.log.

RE: use system ffmpeg // vaapi support - Added by saen acro over 5 years ago

20.04 have some problems as I see in lot of forums and ffmpeg mails.
Intel 100% have bigger problems they cannot write software.
They destroyed QSV now offer OneAPI

RE: use system ffmpeg // vaapi support - Added by Hans Müller over 5 years ago

Thank you so far.

But I have 20.04 working with the Intel drivers. So system ffmpeg is working with vaapi.
some variables in the auto script build for ffmpeg seem not to be compatible with the drivers I am running.

As I mentioned, I can build the tvheadend ffmpeg version with the following variables.

$ cd /tmp/tvheadend/build.linux/ffmpeg/ffmpeg-4.1.5
$ FFMPEG_PREFIX=/tmp/tvheadend/build.linux/ffmpeg/build/ffmpeg PKG_CONFIG=/tmp/tvheadend/support/pkg-config.ffmpeg ./configure --prefix=/ffmpeg --enable-shared --enable-vaapi --enable-gpl --enable-libx264 --enable-libx265

there must be a way, either to let tvheadend use the system ffmpeg or to adjust the variables autobuild uses.

RE: use system ffmpeg // vaapi support - Added by saen acro over 5 years ago

https://github.com/tvheadend/tvheadend/blob/master/Makefile.ffmpeg#L593
vaapi check I guess

https://github.com/tvheadend/tvheadend/blob/master/Makefile.ffmpeg#L656
configuration part

do some experiments :)

RE: use system ffmpeg // vaapi support - Added by Hans Müller over 5 years ago

Update, got tvheadend working at least with h264_vaapi.
hevc_vaapi and vp9_vaapi not working at the moment, not sure why yet.

GPU is?
embeded opensource driver in kernel or proprietary used?

RE: use system ffmpeg // vaapi support - Added by Hans Müller over 5 years ago

yep tvheadend is using the gpu for h264 transcoding.
i am using the intel media driver

There are some extra packages with must be installed to run proprietary functions

RE: use system ffmpeg // vaapi support - Added by Hans Müller over 5 years ago

Yes I know.

hevc and vp9 works with ffmpeg alone. also tvheadend is showing it in the streams options as hevc_vaapi.
But when I try to use it, it ends with "unknown error detected"

RE: use system ffmpeg // vaapi support - Added by Hans Müller about 5 years ago

I give up for now. I can live with just H246.
Maybe I will try again my setup with Ubuntu 18 in the next weeks.
