Hi
we are using an inference pipeline with below components used also in “deepstream-app”
inputComponent -> nvstreammux -> primaryGieBin (nvInfer with yoloPlugin) -> nvTrackerBin -> nvStreamDemux -> OutputComponents
It happen that
-) we start previuos pipeline 1st time and inject videostrem
-) in this way we get metadata of objects detected and we can use them like we need
-) so pipelines component works correctly and all is ok
-) then we destroy inference pipeline and restart again the same pipeline
-) but during pipeline starting we get below BackTrace
trying to find some solution we see that at following link was filed a very similar situation
https://forums.developer.nvidia.com/t/yolo-inference-library-issue/154891
So in file
yoloPlugins.cpp
there is this macro
REGISTER_TENSORRT_PLUGIN(YoloLayerV3PluginCreator);
and it seems there is some static variable inside it that should be at the basis of below crash,
But it is not clear what is the solution proposed in the thread,
May you suggest the correct way to run more times same inference pipeline and to avoid below crash
thanks for support,
M.
