noticing your RTSP fps is 25fps, what is the perf output when run 4 RTSP? you can find it like this: **PERF: {‘stream0’: 16.19} this issue should be inference speed is not as fast as RTSP fps, in this case, RTSP receiving element will drop packets if drop-frame-interval is True, you can s…

I have noticed issue emerges when we have 4 streams. In the screenrecord, I have run two deepstream python apps simultaneously. You can see the difference

I ran your GST command. The output of that video is fine. Is there any gst command for generating a tiled output of 4 streams?

in your “2022-07-29 11-18-43.mkv”, how do your see that three videos? I did not see “python3” caption, is it a thirdpart tool? if yes, it should be network issue, you can start four commandline to verify, gst-launch-1.0 uridecodebin uri=rtsp://xxx1 ! nvvideoconvert ! autovideosink gst-la…

Unable to start four gst streams [Screenshot 2022-08-03 170659]

Also, python3 disappears when window is maximized. When I make it small, I can see python3 written there, so that’s not an issue.

[Screenshot 2022-08-03 172424] Here is system monitor when running RTSP streams, looks fine to me. But the stream is still not looking good.

Also, tried HVEC recorded video samples you mentioned, they are working fine. Issue seams to be when running more than 1 rtsp streams. Can you try running yourself on any jetson nano?

I will reproduce locally. do you mean running 4 local hevc video is ok? like this, python3 deepstream_imagedata-multistream.py file:///hevc1 file:///hevc2 file:///hevc3 file:///hevc4 frames, if that, it should not performance issue. does it have mosic at the start time if run 4 rtsp hevc …

Sure Yes, local files work fine I am not sure what mosic means. If you mean mosaic, isn’t that the tiled display? Yes, one stream runs fine in gst.

So I have narrowed down the issue. It happens when Deepstream has to interact over local network. I used rtspout.py example to generate a stream. The stream when played on jetson, works fine. But when playing same stream on another computer on the network, it doesn’t play well.

Also, I get these warnings in the start of pipeline, do these have anything to do with all this?
