Different multi rtsp dealy,but same is real time

I created a link

uricodebin streammux pgie tiler nvvidconv nvosd nvvidconv_postosd caps encoder rtppay sink

thats is test3 add rtsp-out

if i input the same rtsp stream ,the fps is 25
but i input differenet ,the fps is 16,the stream will delay

Why is that?

#3

Have you modified deepstream-test3? How do you measure FPS with deepstream-test3? Do you know the original frame rate of each rtsp source you used?

#4

Have you modified deepstream-test3?
Yes I add test1-rtsp-out

How do you measure FPS with deepstream-test3?
Use Common.FPS import GETFPS

Do you know the original frame rate of each rtsp source you used?
25fps

#5

Can you provide your python script?

#6

My python script
a.py (15.0 KB)

thats out
FPS*******************
Fps of stream 0 is 16.6
Fps of stream 1 is 25.0

#7

Can you set ‘batch-size’ of nvstreammux to number_sources? Please change ‘sink.set_property(‘sync’, 1)’ to ‘sink.set_property(‘sync’, 0)’

#8

ok, i will change it, and report .
btw,the udpsink not has ‘sync’ in this web, Can you provide some information？

this web : https://gstreamer.freedesktop.org/documentation/udp/udpsink.html

‘sync’ is from GstBaseSink https://gstreamer.freedesktop.org/documentation/base/gstbasesink.html?gi-language=c, most sinks are derived from it.
