Gstreamer nvvidconv missing properties


I’m trying to crop a RTSP stream with the GPU of a Apalis tk1. For this I wanted to use Gstreamer, to get the stream and maybe change it with Gstreamer as well. I read a artikel of Nvidia that contains information about accelerated Gstreamer. I think I followed their installation to the letter and I do have all the elements. But some elements are missing properties I wanted to use.

For example the nvvidconvert element is missing the cropping properties. This would be usefull for me.

Does anyone know if I need to change or reinstall my system, to get the right components I need? I’m running on a L4T system and it also should have jetpack (as I chose this with the toradex easy installer). Then I followed the accelerated gstreamer document to install the gstreamer elements, which was as followed:

sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo apt-get update
sudo apt-get install gstreamer1.0-tools gstreamer1.0-alsa
gstreamer1.0-plugins-base gstreamer1.0-plugins-good
gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly
sudo apt-get install libgstreamer1.0-dev

Can someone explain me why elements are missing properties in the first place?

Kind regards

What exact property of which exact gstreamer plug-in are you missing?
