| NvDsMetaCopyFunc _NvDsMeta::copyfunc |
A callback to be called when meta_data is to be copied or transformed from one buffer to other.
meta_data and user_data are passed as arguments.
Definition at line 97 of file gstnvdsmeta.h.
| NvDsMetaReleaseFunc _NvDsMeta::freefunc |
A callback to be called when meta_data is to be destroyed.
meta_data and user_data are passed as arguments.
Definition at line 101 of file gstnvdsmeta.h.
| NvDsMetaReleaseFunc _NvDsMeta::gst_to_nvds_meta_release_func |
A callback to be called when meta_data transformed into NvDsUserMeta is to be destroyed.
This function must be provided by a GStreamer plugin that precedes Gst-nvstreammux in the DeepStream pipeline.

| NvDsMetaCopyFunc _NvDsMeta::gst_to_nvds_meta_transform_func |
A callback to be called when meta_data is transformed into NvDsUserMeta.
This function must be provided by a GStreamer plugin that precedes Gst-nvstreammux in the DeepStream pipeline. Gst-nvstreammux copies meta_data to user meta data at frame level inside NvDsFrameMeta. meta_data and user_data are passed as arguments.
To retrive the content of meta_data, iterate over NvDsFrameMetaList. Then search for meta_type of NvDsUserMeta which the user has attached. (See deepstream-gst-metadata-test source code for more details.)
meta_data and user_data are passed as arguments.

| gpointer _NvDsMeta::meta_data |
Holds a pointer to metadata.
Must be cast to another structure based on meta_type.
Definition at line 86 of file gstnvdsmeta.h.
| gint _NvDsMeta::meta_type |
Holds the type of metadata, one of values of enum GstNvDsMetaType.
Definition at line 92 of file gstnvdsmeta.h.
| gpointer _NvDsMeta::user_data |
Holds a pointer to user-specific data .
