Hi, this simple code snippet crashes with a Segmentation fault (tested on JetPack 4.3): https://paste.gnome.org/pw1vudabr a quick fix would be highly appreciated. Stacktrace: #0 0x0000007fb6f233f4 in find_notify (object=0x7fa8ff850e, object=0x7fa8ff850e, data=0x0, notify=0x0, match_notify=0, q…

hello arne.caspari, thanks for sharing simple code-snippet for reference, we’re able to reproduce the issue locally. we’ll check this internally.

hello arne.caspari, I’ve revert the code snippet that trigger segmentation fault, please replace the argus library with devtalk1070455_Feb10.tar.gz for your temporary solution. we’ll also investigate the fix, thanks devtalk1070455_Feb10.tar.gz (29 KB)

Hello Jerry, I am having the same problem as Caspari, I tried your temporary solution. Indeed nvarguscamerasrc no loger segfaults but it seems I am getting black images (empty buffers) from gstreamer after I set the pipeline again to play. The pipeline I am using for testing is: nvarguscamerasrc !…

hello ricardo.juarez, I’ve tried locally to confirm gst pipeline and also the python script in comment #1 works with temporary approach. could you please share the failure messages, may I also know what’s the sensor you’re used. thanks

So this is very similar if not the exact issue I complained about in R32.1. It seems it still exists in R32.3.1. What is the time table for a fix for this? EDIT: Note that in R32.1 not only did nvargus-daemon segfault and/or hang, but there were spurious bus messages that would occur if you restar…

Hi All Please have a try the attached lib to fix the problem. libgstnvarguscamerasrc_tx2_xaver.so.txt (81.5 KB)

Hello Shane, It looks like this last update fixes the problem for me. When are you planning to officially release this version of the argus camera plugin ?

Next release should include this fixed.

ShaneCCC is this fix good for the TX2? I would assume so.

So I am using r32.3.1 how do I determine if this patch is in my system, and if not in my system how do I get it What type of debugging do I need to do to determine why setting my pipeline to NULL is still hanging. Also I put in code to kill -9 my app and now I get Argus: Errors if I restart my app…
