How to install gstreamer (1.22) with the vah264enc element

I have Ubuntu 22.04.5 installed on pc with Intel Core i5-6400 CPU with Mesa Intel HD Graphics 530.
I have installed the graphic card related drivers and programs

sudo apt install -y intel-opencl-icd intel-media-va-driver-non-free libmfx1 libvpl2 libegl-mesa0 libegl1-mesa libegl1-mesa-dev libgbm1 libgl1-mesa-dev libgl1-mesa-dri libglapi-mesa libgles2-mesa-dev libglx-mesa0 libigdgmm12 libxatracker2 mesa-va-drivers mesa-vdpau-drivers mesa-vulkan-drivers va-driver-all vainfo hwinfo clinfo

The output of the vainfo as follow:

libva info: VA-API version 1.14.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_14

      VAProfileHEVCMain               :	VAEntrypointFEI

From the default ppa the Gstreamer was installed including gstreamer1.0-plugin-bad, where vah264enc should be located, but command gst-inspect1.0 va and gst-inspect1.0 vah264enc gives No such element or plugin.

The gstremer version installed is 1.22.00

So I just wonder is there are some trick to do to have vah264enc to be installed?

Hello, it might be installed already. Try with sudo: sudo gst-inspect-1.0 va

I ran into this issue last year trying to use vaapi(the old name for intel hardware elements). I also made a note for my future self saying it needed “i965-va-driver-shaders” but that might just be for vaapipostproc and will vary depending on your specific type of processor/gpu. You might be able to change the permission to not require sudo, you can see the complete path to the .so files in gst-inspect, but idk.
