Internal data stream error while running CSI camera on deepstream-test 2 application

I am running deepstream test-2 application on jetson nano and I made some changes in that for CSI camera but getting error like:

please help me out

Sorry for a late reply, i see another post from you which can open the CSI camera, so seems you solve the problem? please let me know, if you still have problem, please update with your latest issues regarding this topic.

hello amycao,
I am still having the same issue I had just change the linking order in pipeline that’s why i was able to run camera but unable to get detection or unable to draw line.
Please help me out.

similar issue with, seems your issue solved, right?
