I try to modify sample2 to work with USB webcam. It fine working with DeepStream 2.0, but crash with 3.0.

Same happens when i try run it with:
gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg,width=1600,height=1200,framerate=15/1 ! \
jpegparse ! jpegdec ! videoconvert ! videoscale ! video/x-raw,width=1280,height=720,format=NV12 ! nvvidconv ! \
"video/x-raw(memory:NVMM),format=NV12" ! nvinfer config-file-path=./dstest2_pgie_config.txt ! nvtracker
When I remove nvtracker will not crash. Interestingly, the example (without modifications) works fine.

I also try other pipeline:
this working:
gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg,width=1600,height=1200,framerate=15/1 ! jpegparse ! jpegdec ! videoconvert ! videoscale ! video/x-raw,width=1280,height=720,format=NV12 ! nvvidconv ! video/x-raw\(memory:NVMM\),format=NV12 ! nvinfer config-file-path=./dstest2_pgie_config.txt ! nvvidconv ! nvosd ! nveglglessink sync=false
this same problem:
gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg,width=1600,height=1200,framerate=15/1 ! jpegparse ! jpegdec ! videoconvert ! videoscale ! video/x-raw,width=1280,height=720,format=NV12 ! nvvidconv ! video/x-raw\(memory:NVMM\),format=NV12 ! nvinfer config-file-path=./dstest2_pgie_config.txt ! nvtracker ! nvvidconv ! nvosd ! nveglglessink sync=false
Maybe i have wrong version OpenCV? Or wrong build?
