I try to use gst-nvivafilter according to the Tegra X1/Regra Linux Driver Package Multimedia User Guide. The pipeline is as below.
gst-launch-1.0 filesrc location='/home/ubuntu/Documents/WORK/testvideo.mp4' ! qtdemux ! h264parse ! omxh264dec ! nvivafilter cuda-process=true customer-lib-name="libsample_process.so" ! nvoverlaysink -e
But an error occurred.

Freeing pipeline ...
Thanks for your help.
And I have another question.
I want to create a gst_plugin according to the website,
Plugin Writer's Guide
But it seems can not run on the TX1.
The pipeline as below.
gst-launch-1.0 filesrc location='/home/ubuntu/Documents/ZLC_WORK/testvideo.mp4' ! qtdemux name=demux ! queue ! h264parse ! omxh264dec ! nvvidconv ! 'video/x-raw, format=(string)GRAY8' ! zhufilter ! videoconvert ! xvimagesink -e
The error code is as below.

Could you give me suggestion about the difference between GST-Plugin making on TX1 and Desktop.
Any suggestion will be appreciated. Thanks in advance.
It’s hard to know with so few details about your plugin.
It works without zhufilter in the pipeline, so I’d suspect it is the guilty.
You may try to set GST_DEBUG in order to get more informations:
# Set GST_DEBUG to level 3 for any plugin
GST_DEBUG=*:3 gst-launch-1.0 filesrc location='/home/ubuntu/Documents/ZLC_WORK/testvideo.mp4' ! qtdemux name=demux ! queue ! h264parse ! omxh264dec ! nvvidconv ! 'video/x-raw, format=(string)GRAY8' ! zhufilter ! videoconvert ! xvimagesink -e
