Hello, I’m sorry for bringing this topic again ( Gstreamer Pipeline issue : PosixMemMap:84 mmap failed ) but because I didn’t reply faster it got closed. However, my problem is not really solved. I have tried to do both a gst-launch pipeline and a python pipeline. The one that I launch through the co…

Hi, Linking each camera to fakesink is for testing purpose. To avoid switching between the cameras. Since dynamic unlinking/linking is not supported. For a real use-case, would suggest link to udpsink. And you can construct the pipeline with udpsrc to decode the stream and display. And can switch …

Hi, Have you tried the case to replace v4l2src with videotestsrc is-live=1? The issue looks to be in stability of camera sources. Not an issue in Deepstream plugins. Would suggest try other sources(such as videotestsrc, or rtspsrc) to clarify this first.

Hello, I have tried with videotestsrc with gst-launch command and it works. I have done tests on my own also and those tests worked even after 24h : test 1 : 4 independent pipelines at the same time : gst-launch-1.0 v4l2src device=/dev/video0 ! “video/x-raw, format=(string)UYVY, width=(int)1920,h…

Hello, Maybe I was not clear enough. Those gstreamer pipelines work but not through the deepstream python librairy, it is why I have provided to you a github link with an implementation of the pipeline. I would be grateful if you can have en eye on this code and test it on your side.

Hi, Those commands above run without problems through the terminal. When I launch them through Deepstream python library (code provided on my GitHub), I have the problem that appears after 1h30min.

Hi, If gst-launch-1.0 command works and it is specific to python app, it may be an issue in python binding. Since it is open source, please download the source code: deepstream_python_apps/bindings at master · NVIDIA-AI-IOT/deepstream_python_apps · GitHub And follow the guidance to build it wit…

Hello, Is it possible that you try to run my python code to see if you have the same problem as me ?

Hi, We are not able to run the script since our USB cameras are not identical. The supported formats are different. So would need your help to test with videotestsrc. If it is something wrong in python binding, we should also observe it while using videotestsrc

Hello, I have tried replacing v4l2src by videotestsrc and it crashed after 1h11min using the python script that I have provided. It crashed with the same error.

Hi, Please modify the sample to use videotestsrc so that we can try. And do you use 5.1.3? We have 6.0GA release and would suggest upgrade to the version and try.

Hi,
Gstreamer Pipeline issue : PosixMemMap:84 mmap failed - #11 by DaneLLL

Do you mean if you run above command with your cameras, it can pass long run? We run it over weekend and there’s no issue.
