The gst-nvstabilize element can be easily incorporated into any pipeline. Here we present some sample pipelines for different use cases.

Processing buffers from v4l2 device



Controlling ROI with CropMargin

The following pipelines will capture from a camera a 1280x720 video stream, will use a 0.1 crop margin, and produce a stabilized 1280x720 output. Note that the output is scaled to match the input size.

Troubleshooting

If you see this error when trying to display directly from the local display, execute the following command on the target before starting the video decode pipeline: 

Using winsys: x11 
ERROR: Pipeline doesn't want to pause.
Setting pipeline to NULL ...
Freeing pipeline ...

export DISPLAY=:0
