Documentation Clarification Needed - Time Units for Frame Metadata Parameters

[Levi_Pereira]

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU)
GPU
• DeepStream Version
7.1
• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
new requirements
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)

I am currently working with the DeepStream Python API , specifically with the NvDsFrameMeta class. I noticed that the documentation lacks specific information about the time units for two important parameters:

1. buf_pts (presentation timestamp)
2. ntp_timestamp (network time protocol timestamp)

While the documentation states that both parameters are of type ‘int’, it would be very helpful if the documentation could specify the time units used (seconds, milliseconds, or nanoseconds) for each parameter.

Could you please update the documentation to include this information? This clarification would help developers work more accurately with timing-related features.

Thank you for your attention to this matter.

DeepStream is based on GStreamer. All timestamp is aligned with GStreamer timestamp. GstClockTime

Thank you
It would be helpful if the documentation referenced GstClockTime or mentioned that this data is in nanoseconds format.
