Adjusting muxer's batch push timeout based on FPS of fastest source 40000

Please provide complete information as applicable to your setup.

• Hardware Platform (GPU)
• DeepStream Version 6.0

在deepstream config中的[source]中设置drop-frame-interval=5，（实际帧率是25FPS，这样的话后边infer帧率便变成了25/5=5FPS）。于是在[streammux]中设置batched-push-timeout=200000（1s/5=200ms）,但当程序运行时会自动改成40ms。不知道能否强行使用我自己设置的200ms呢？谢谢

sorry.
RTSP internal camera frame rate is 25FPS. in deepstream config, I set Set drop-frame-interval = 5 [source]. and in [streammux], set batched-push-timeout=200000 (1s/5=200ms), but automatically changed to 40ms when the program runs. I wonder if I can force use the 200ms set by myself?

below is part of my config txt:

@bpheng

but automatically changed to 40ms when the program runs.

How did you know the timeout is automatically changed to 40ms when the app runs?

and I find this message" Adjusting muxer’s batch push timeout based on FPS of fastest source %d" in file /opt/nvidia/deepstream/deepstream-6.0/lib/gst-plugins/libnvdsgst_multistream.so

@Fiona.Chen hi, FIona. How can I do using batched-push-timeout=200000 runing on the sample deepstream-spp?

[Fiona.Chen]

For live stream, please disable “sync-inputs” in nvstreammux.
