Hi, what is the expected input meta that gst-nvtracker is looking for in the input stream? Documentation mentions that it should be NvDsBatchMeta, but from what I understood, this is a general meta type. I would imagine that it would look for NvDsObjectMeta, but wasn’t able to find any references to this in the documentation.

Hi
The input is batched gst buffer and NvDsBatchMeta, it will need this to access object metadata, you can check this for struct of NvDsBatchMeta,

and https://docs.nvidia.com/metropolis/deepstream/plugin-manual/index.html#page/DeepStream%20Plugins%20Development%20Guide/deepstream_plugin_details.3.02.html#wwpID0E0G40HA for how low level tracker working.
