Problem with frame_meta->buf_pts on Axis camera

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Xavier AGX
• DeepStream Version 4.0
• JetPack Version (valid for Jetson only) 4.3
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Sample application and the configuration file content
• Reproduce steps
• Reproducing rate and duration

I use code depending on deepstream-test3_app.c. And I use uridecodebin and rtsp stream from Axis camera.
In gst-example I print frame_meta->buf_pts every second, but delta of two neighborhood buf_pts is ~0.6 sec

Can you upgrade to DeepStream 5.0 GA?

buf_pts in meta data is get from the video buffer timestamp when the stream goes into nvstreammux. It is not generated by DeepStream, it comes from the RTSP stream. There is only one stream in your test, right?
It is better to set “live-source” property of nvstreammux when you using RTSP sources. And the “sync=0”, “async=false” property setting with sink plugin will also help.

All of these properties are set.
I have only one stream.
Maybe this is a problem due to the fact that the camera produces 12 FPS

Can you try with another camera to confirm?

Hi, @kayccc!
I find the problem. The priority was be set to image quality. When I set priority to fps - all work fine!

Glad to know issue resolved, thanks for the update.
