What is the difference between Frame Meta, Object Meta and User Meta?
Please explain in Layman terms. I know they are nested and looked up at the docs but was still unable to decipher it.
There is no update from you for a period, assuming this is not an issue anymore.
Hence we are closing this topic. If need further support, please open a new one.
Thanks
You can refer the relation on this link: MetaData in the DeepStream SDK — DeepStream 6.1.1 Release documentation, and the structure definition in sources/include/gstnvdsmeta.h
.
NvDsBatchMeta
corresponds to meta in batch of frames, and NvDsFrameMeta
is for the metadata in each frame, it can hold several Object Meta(NvDsObjectMeta
) and User Meta (NvDsUserMeta
).
You can also refer the sample code on how to extract the meta data, for example, function osd_sink_pad_buffer_probe
in deepstream_test1 (C/C++ Sample Apps Source Details — DeepStream 6.1.1 Release documentation, and source directory /opt/nvidia/deepstream/deepstream-6.1/sources/apps/sample_apps/deepstream-test1)
