Hi. I tested live-source option for multi camera syncing. Jetson Xavier, JetPack 4.3, DeepStream 4.0 When I tested 8 cams in gstreamer pipeline with live-source option on, it worked. gst-launch-1.0 \ uridecodebin uri=RTSP_SRC0 ! nvvideoconvert ! m.sink_0 \ ... uridecodebin uri=RTSP_SRC7 ! nvvid…

We will fix the problem in next release.

Can this problem be reproduced with just two rtsp streams?

I think it only works when I use 2 cams. Below is the result according to the number of cameras in Xavier NX (JetPack 4.4). 2 cams [ 398 ] 0: 1599108010043333333 1: 1599108010042333333 [ 399 ] 0: 1599108010076666667 1: 1599108010075666666 [ 400 ] 0: 1599108010110000000 1: 1599108010109000000 [ 40…

NTP can not be supported with your “gst-launch-1.0” pipelines, how do you implement the NTP functions? What have you modified and how do you get NTP timestamp from the pipeline? DeepStream 4.0 does not support NTP while DeepStream 5.0 has implemented the function of attaching system timestamp to th…

As I said, it happens when I use Jetson Xavier NX with DeepStream 5.0. The pipeline above is just a sample. I use C code for implementation. The code below is part of the code. GstCaps* caps_filter_src = gst_caps_from_string("video/x-raw(memory:NVMM), format=RGBA"); for (int i = 0; i < CAM_NUM; +…

We do have configure_source_for_ntp_sync() in DeepStream 5.0. But how could you get NTP timestamp with DeepStream 4.0? You have mentioned case 1 is tested with DS 4.0. And if you want to send batched buffer of streammux at regular interval, you can set “batch-push-timeout” property of nvstreammux. h…

In case 1, multi-camera syncing worked. (I mean there are no ntp timestamp, I just set option “live-option” true.) When I looked at each frame one by one in my eyes, it worked. But In case 2, when I looked at each frame one by one in my eyes, it didn’t work. So I print out ntp timestamp. (in onl…

So there is no NTP timestamp print with case 1, right? Do you think “live-source” property with nvstreammux will make the multiple camera videos sync?

Yes. There is no NTP timestamp print with case 1. In case 1, “live-source” property with “nvstreammux” makes the multiple camera videos sync. In case 2, it doesn’t.

Hi. Is there anything I can do?

Hi.
I heard DeepStream 5.1 version has been released. (Announcing new software update for DeepStream 5.1)
Was this problem solved here?
