retinex element of gstreamer on Jetson

Autonomous Machines Jetson & Embedded Systems Jetson TX2

Dear,

I would test retinex element on Jetson TX2, for both CSI-2 and USB camera.

JetPack ver: R28.2.1
gstreamer1.0-plugins-bad installed

After plugin installation, firstly tested test-video-src and got following errors;

nvidia@tegra-ubuntu:~$ gst-launch-1.0 videotestsrc ! decodebin ! videoconvert ! retinex ! videoconvert  ! nvoverlaysink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0: Internal data flow error.
Additional debug info:

streaming task paused, reason not-negotiated (-4)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...

This time, I tested USB camera as follows;

nvidia@tegra-ubuntu:~$ gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,framerate=30/1,width=1280,height=720 ! retinex ! nvoverlaysink
Setting pipeline to PAUSED ...

[updated]

  1. I made sure this Retinex element on x86_64 works well.
  2. gstreamer1.0-plugins-bad package for aarch64 does not have retinex element.

Any someone give me hints to run retinex on Jetson ?

Thanks

Hi,
I am able to run below command:

$ export DISPLAY=:0
$ gst-launch-1.0 videotestsrc ! retinex ! videoconvert ! xvimagesink

retinex is not owned by NVIDIA. For more help and suggestion, you may go to

Hello Dane,

Did you run the command on Jetson?
When it comes to sw package info, I could not find retinex element in aarch64 version package.

Thanks

I can see it after installing gstreamer1.0-plugins-bad.
