H264 HW decoder in GStreamer for Orin

[MichaelPres]

Hi,

I am trying to use the h264 hardware decoder on Orin with Kirkstone. When I follow the machine config file, the

meta-tegra/conf/machine/jetson-agx-orin-devkit.conf
    require conf/machine/include/tegra234.inc
        require conf/machine/include/tegra-common.inc
		MACHINE_HWCODECS = "gstreamer1.0-plugins-nvvideo4linux2"

First, the recipe seem to be for gstreamer 1.14: meta-tegra/recipes-multimedia/gstreamer/gstreamer1.0-plugins-nvvideo4linux2_1.14.0-r35.4.1.bb
When I add it, it appear blacklisted in gstreamer:

rhc@jetson-agx-orin-devkit:~$ gst-inspect-1.0 -b
Blacklisted files:
libgstnvarguscamerasrc.so
libgstnvcompositor.so
libgstnvdrmvideosink.so
libgstnvivafilter.so
libgstnvv4l2camerasrc.so
libgstnvvidconv.so
libgstnvvideo4linux2.so

How can I use the h264 decoder?

Also, library from libgstnvvideo4linux2.so does not have the execution permission like the others:

It's difficult to say with so little information to go on, but my guess is that your build is missing drivers and/or libraries that those plugins need.

Shared object libraries don't need execution permissions.

Did you see it working in one of the tegra-distro-demo image?

[madisongh]

Yes, it gets tested in the demo-image-sato and demo-image-weston images we build in the demo distro, via the sinteltest script.

[MichaelPres]

Since I am running gst-inspect with a non-root user, udev rule are missing.

[bchoineubility]

I did same mistake one day. ;)
