DeepstreamSDK 4.0 on Xavier

I ran a sample program attached to DeepstreamSDK 4.0 on Xavier(Jetpack4.2.1)
and got 3 FPS with the following warning message.

WARNING from sink_sub_bin_sink1: A lot of buffers are being dropped.
Debug info: gstbasesink.c(2902): gst_base_sink_is_too_late (): /GstPipeline:pipeline/GstBin:processing_bin_0/GstBin:sink_bin/GstBin:sink_sub_bin1/GstEglGlesSink:sink_sub_bin_sink1:
There may be a timestamping problem, or this computer is too slow.

On the other hand, published fps value is 30 with 32 streams
in this public page “” .

What is the cause for this mismatch?

Please try

Thanks, It was very helpful.

Is 30FPS possible with ‘sync=1’?
