    Merge pull request #69 from 0ct0cat/deepstream-6.2  
    suppport deepstream-6.2  **<-- Does it mean that DS 6.3 is not yet supported?**
  1. Copy the directory deepstream-occupancy-analytics/ to deepstream/sources/apps/sample_apps/
  2. Follow deepstream-occupancy-analytics/README to download the pre-requirements and to build the code.
    (I needed to add this line into deepstream-occupancy-analytics/Makefile:
CFLAGS+= -I/usr/include/gstreamer-1.0 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include
  1. Edit deepstream-occupancy-analytics/config/dstest_occupancy_analytics.txt to disable source1 and sink1.
  2. Edit deepstream-occupancy-analytics/config/nvdsanalytics_config.txt to redraw the Entry and Exit lines:
line-crossing-Exit=400;1050;450;850;50;850;850;850;
line-crossing-Entry=500;500;450;700;50;700;850;700
  1. ./deepstream-test5-analytics -c config/dstest_occupancy_analytics.txt
  2. The sample app runs. People are crossing the lines (visual checking), but line crossing counters are not updated, as shown below:

• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description) ---- Unsure if it’s relevant.

Thank you. That did the trick.

Maybe the config file in the deepstream-occupancy-analytics repository should be updated with this line.
