Building gst-msdk with MediaSDK opensource

I tried, several months ago, the open source version of Intel MediaSDK and it was a complete mess. In order to review some patches for gst-msdk I tried it again. I am surprised how the situation has improved since then.

Install dependencies

$ sudo apt get install libva-dev vainfo cmake ccache
$ sudo apt build-dep gstreamer1.0 gst-plugins-{base,good,bad}1.0
$ sudo apt remove libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev

Seting up the workplace

$ sudo mkdir /opt/intel
$ sudo chown usuario:usuario /opt/intel
$ mkdir ~/msdk
$ cd ~/msdk

Build MediaSDK

It will be built in its source directory: ~/msdk/MediaSDK/build

It will be installed in /opt/intel

$ git clone
$ cd MediaSDK
$ mkdir build
$ cd build
$ cmake ..
$ make
$ make install

Build media-driver

$ cd ~/msdk
$ git clone
$ git clone
$ mkdir build
$ cd build
$ cmake ../media-driver
$ make

Let’s install media-driver in /opt/intel too

$ cd ~/msdk/build
$ cp ./media_driver/ /opt/intel

But don’t remove, rename or move the directori ~/msdk/build because links against which is there. Thus either you keep the directory or you install that library in a path searchable by the linker, or set the environment variable LD_LIBRARY_PATH

Setup gst-build

It will be build in its source directory: ~/msdk/gst-build/build

$ cd ~/msdk
$ git clone
$ cd gst-build
$ export INTELMEDIASDKROOT=/opt/intel/mediasdk
$ meson build -Dpython=disabled -Dgst-plugins-bad:msdk=enabled
$ ninja -C build

Check for build elements

$ ninja -C ~/msdk/gst-build/build  uninstalled

Remember to export these environment variables (perhaps you what to create a script file to set them):

export LIBVA_DRIVERS_PATH=/opt/intel
