Deepstream 5 timestamp always 0

• DeepStream Version 5.0 GA

i have set:
streammux.set_property(‘attach-sys-ts’, True)
or
streammux.set_property(‘attach-sys-ts’, 1)

but it have value 0 on
frame_meta.ntp_timestamp

Why ?

Could you share your setup with us?
Are you using python app?

i have:

log_info("Creating streammux")
streammux = Gst.ElementFactory.make("nvstreammux", "stream-muxer")
if not streammux:
    log_err(" Unable to create NvStreamMux")
if USE_CSI_CAMERA:
    streammux.set_property('live-source', 1)

log_info("Playing... ")
streammux.set_property('width', pc_ds.frame_w)
streammux.set_property('height', pc_ds.frame_h)
streammux.set_property('batch-size', 1)
streammux.set_property('batched-push-timeout', 40000)
streammux.set_property('attach-sys-ts', True)
pgie.set_property('config-file-path', "./people_counter_ds/configs/config_infer_primary_nano.ini")

pipeline.add(streammux)

streammux_sinkpad = streammux.get_request_pad("sink_0")

streammux.link(pgie)

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Would you mind to share your setup and your source code which can be compiled and run well, so I can try locally.
