Issue running app in Deepstream 6.0.1 container

[coffeycan]

Am trying to build / run the occupancy example in a 6.0.1 devel container.

Am running w/o an X display, but really just want to see the msg broker counts / occupancy. Is that possible?

Have updated makefile and low-level object tracker references per:
https://docs.nvidia.com/metropolis/deepstream/6.0/dev-guide/text/DS_Application_migration.html

Initially got this output:

I don't see any messages on the msg broker console.

To fix the Glib Critical errors, tried what I think was the solution for Issue 12, by replacing:
/opt/nvidia/deepstream/deepstream-6.0/lib/libnvds_msgconv.so
with:
/opt/nvidia/deepstream/deepstream-6.0/sources/apps/sample_apps/deepstream-occupancy-analytics/bin/x86/libnvds_msgconv.so

Now the critical GLib errors are gone, but other errors have emerged:

Any ideas? Has this example been shown to run on 6.0[.1]?

The smart-rec-video-cache error can be fixed simply by replacing

"smart-rec-video-cache" with "smart-rec-cache"

under [source1] in config/test5_config_file_src_infer_tlt.txt
