Plugins require GStreamer version >= 1.14 because use field 'params' in struct GstVideoRegionOfInterestMeta introduced in GStreamer 1.14.
On Ubuntu 16.04 the easiest way is to build and run docker container with all dependencies including GStreamer.
On Ubuntu 18.04 the apt-get installs GStreamer version 1.14 compatible with plugins.

hi, thanks, with docker image, i have successfully launched the sample.

[mikhail-nikolskiy]

Update on this question.
We will try to improve compatibility with GStreamer version less than 1.14 for elements gvainference and gvadetect on one of next updates.
The field 'params' in struct GstVideoRegionOfInterestMeta only used in gvaclassify element.
