Hi,

(follow up on: AGX Xavier: get Gstreamer nvvidconv and others )

I got all the needed libraries needed and added the correct LD_LIBRARY_PATH etc for my custom system.

Unofrtunate, I got following error when trying to run gst-launch-1.0 -v videotestsrc pattern=smpte ! video/x-raw,width=1280,height=720 ! fbdevsink 

root@mycompany:~# gst-launch-1.0 -v videotestsrc pattern=smpte ! video/x-raw,width=1280,height=720 ! fbdevsink 
NvRmMemInitNvmap failed with No such file or directory
549: Memory Manager Not supported
****NvRmMemInit failed**** error type: 196626
*** NvRmMemInit failed NvRmMemConstructor

did I miss something on adding the libraries?
All sources used are based on the original 35.1 and Jetpack 5.0.2 sources.

gst-inspect-1.0 -b gives me my blacklisted nv* plugins

loaded nvgpu.ko and nvmap.ko seems to solve this.

Getting some stranger stuff with this now:

Hi,
We don’t have much experience about using fbdevsink plugin. This would need other users to check and give suggestion.

Not sure if your use-case is to send video content to another process or device. If yes, you may try RTSP and UDP. Please take a look at Jetson AGX Orin FAQ

Q: Is there any example of running RTSP streaming?
Q: Is there an example for running UDP streaming?

The above ‘command’ is just to verify I Have access to the NVidia hardware.
I wanted to stream the smpte pattern to the HDMI port on board of the dev-kit.
using gst-launch-1.0 -v videotestsrc pattern=smpte ! video/x-raw,width=1280,height=720 ! fbdevsink this works fine.
I suspect it has something to do with the combonation of the commands.

If you have another approach on verifying I have the right hardware access, please feel free to share :)

It is working, thanks for the help.
I use following command gst-launch-1.0 -v videotestsrc pattern=smpte ! video/x-raw,width=1280,height=720 ! nvvidconv ! "video/x-raw(memory:NVMM),format=RGBA,width=1280,height=720" ! nvvidconv ! "video/x-raw(memory:NVMM)" ! nvdrmvideosink
