Field Documentation
◆ batch_index
| guint GstNvInferFrame::batch_index = 0 |
Index of the frame in the batched input GstBuffer.
Not required for classifiers.
Definition at line 73 of file sources/gst-plugins/gst-nvinfer/gstnvinfer_impl.h.
◆ converted_frame_ptr
| gpointer GstNvInferFrame::converted_frame_ptr = nullptr |
Pointer to the converted frame memory.
This memory contains the frame converted to RGB/RGBA and scaled to network resolution. This memory is given to NvDsInferContext as input for pre-processing and inferencing.
Definition at line 81 of file sources/gst-plugins/gst-nvinfer/gstnvinfer_impl.h.
◆ frame_meta
| NvDsFrameMeta * GstNvInferFrame::frame_meta = nullptr |
Definition at line 69 of file sources/gst-plugins/gst-nvinfer/gstnvinfer_impl.h.
◆ frame_num
| gulong GstNvInferFrame::frame_num = 0 |
Frame number of the frame from the source.
Definition at line 75 of file sources/gst-plugins/gst-nvinfer/gstnvinfer_impl.h.
◆ history
| std::weak_ptr< GstNvInferObjectHistory > GstNvInferFrame::history |
Pointer to the structure holding inference history for the object.
Should be NULL when inferencing on frames.

Definition at line 68 of file sources/gst-plugins/gst-nvinfer/gstnvinfer_impl.h.
◆ offset_left
| guint GstNvInferFrame::offset_left = 0 |
