nvcamerasrc timestamps

I’m looking to get system-level monotonic clock timestamps from the nvcamerasrc object in a gstreamer-1.0 c++ application. It appears that this should be do-able with the “enable-meta” parameter. I have a couple questions:

1.) What is the reference clock of the timestamp from enable-meta?

2.) How can I get this timestamp (or the meta-data in general) out from an appsink element?


hello Allanm,

  1. the sensor time stamp is from kernel time stamps
  2. i think you could refer to this tutorial: https://gstreamer.freedesktop.org/documentation/tutorials/basic/short-cutting-the-pipeline.html
