I’m sorry, I checked again when GST_DEBUG=4, but when I turned off the printing information, I could see that the printing " In cb_newpad ",did not continue to run, and the callback printing In fakesink_src_pad_buffer_probe did not trigger. I hope you can try again.
when I use " ./deepstream-preprocess-test rtsp://127.0.0.1:8554/test 2", there is “data come” printing , when I " ./deepstream-preprocess-test rtsp://127.0.0.1:8554/test 3", there is no “data come” printing, the pipeline is not right, so please check the code and narrow down the issue.
pipeline-3.zip (1007.3 KB)
Incorrect plumbing? There is no problem with the logic of connecting pipelines. I just added one more group of queues, and I can’t find the error by checking the pipeline diagram. This is what I said before when adding many queues, pipelines are incorrect.
When you change int nDeviceNum=25 to int nDeviceNum=15 in the program, you will find that “data come” is also printed when the second parameter is 4, so I think my pipe connection logic is OK, so I suspected that there is an upper limit on the number of pipe components.
I really don’t have any clue about this problem, so I hope you can reply as soon as you have any discovery or progress. Thank you.
did you check the above pipeline-3.zip? the pipeline is wrong, no one link to queue1, but " ./deepstream-preprocess-test rtsp://127.0.0.1:8554/test 2" 's pipeline is ok.
I checked the pipeline drawing carefully and found the problem. I printed GstIterator* pGstIterator = GST_BIN_iterate_elements (GST_BIN(pipeline)); The value of pGstIterator->size has always been 152, which I always thought was the number of components in the pipeline. It was 152 that caused the problem in my code logic. I solved this problem by reassigning. Thank you very much for your help
Glad to know you fixed it, thanks for the update!
