use system ffmpeg // vaapi support

Added by Hans Müller 17 days ago

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 17 days 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

./configure

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 16 days ago

in folder where git clone

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

or use auto script

RE: use system ffmpeg // vaapi support - Added by saen acro 16 days 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 16 days 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.

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?

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"
