Segmentation fault

What does this have to do with? How to fix it?
P.S. In deepstream_dewarper_test.c I commented out everything related to nvinfer and nvtracker, but this error was present before the commenting.

Sorry, so the error disappear after you commenting the nvinfer && nvtracker?

Hello. After commenting nvinfer && nvtracker the error did not go away.

5

OK, can you share a simple repro with us?

6

The problem is exactly that it doesn’t play anything. I try to record video from the camera to a file, but I get an error.
P.S. I may have misunderstood your question.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

So is this issue still a segment fault? Can you share a simple repro with us if yes?
