| struct | _NvDsMetaSubCompLatency |
| Holds information about latency of the given subcomponent. More... | |
| struct | _NvDsMetaCompLatency |
| Holds information about latency of the given component. More... | |
| struct | NvDsFrameLatencyInfo |

Macros | |
| #define | MAX_COMPONENT_LEN 64 |
| #define | nvds_enable_latency_measurement (nvds_get_enable_latency_measurement()) |
| Defines a pseudo-variable whose value is the return value of nvds_get_enable_latency_measurement(). More... | |
Typedefs | |
| typedef struct _NvDsMetaSubCompLatency | NvDsMetaSubCompLatency |
| Holds information about latency of the given subcomponent. More... | |
| typedef struct _NvDsMetaCompLatency | NvDsMetaCompLatency |
| Holds information about latency of the given component. More... | |
Functions | |
| NvDsUserMeta * | nvds_set_input_system_timestamp (GstBuffer *buffer, gchar *element_name) |
| Sets the system timestamp when the Gst Buffer arrives as input at the component. More... | |
| gboolean | nvds_set_output_system_timestamp (GstBuffer *buffer, gchar *element_name) |
| Sets the system timestamp when a Gst Buffer that is pushed to the downstream component. More... | |
| guint | nvds_measure_buffer_latency (GstBuffer *buf, NvDsFrameLatencyInfo *latency_info) |
| Measures the latency of all frames present in the current batch. More... | |
| gboolean | nvds_get_enable_latency_measurement (void) |
Indicates whether the environment variable NVDS_ENABLE_LATENCY_MEASUREMENT is exported. More... | |
| void | nvds_add_reference_timestamp_meta (GstBuffer *buffer, gchar *element_name, guint frame_id) |
| Adds the reference timestamp metadata for this buffer Note: element_name == "audiodecoder" and "nvv4l2decoder" will be used for latency measurement calculations where the timestamp will be used by API: nvds_measure_buffer_latency() to calculate the latency of buffers downstream relative to the decoder.
