A robust integration of Basler's Pylon API with GStreamer. Delivers applications as ready-to-run standalone compiled executables (gst-launch-1.0 is not needed). Designed for reliability and easy access to performance optimizations. Note: This is not a plugin. It is an intergration using GStreamer's GstAppSrc element.

demopylongstreamer binary crashing on ubuntu16.04 #19

Closed harendra247 closed 4 years ago

harendra247 commented 4 years ago

I was trying to make it work on Nvidia Tx2 but I could not succeeded, so thought of trying it on x86_64 (Ubuntu 16.04) and am facing the crash. I am using the following libraries.

Gstreamer version : 1.8.3
Basler pylon lib version : 5.0.12

Below is the back trace . Let me know if more info needed.

Upgraded to Basler Pylon lib version : 5.2.0 and crash got resolved.
