There is a time consuming bug in gstnvarguscamerasrc.cpp.
As shown in the following figure， I can get h264-data/yuv-data 25fps in the appsink/fakesink by using capture single sensor, no matter how many app-bin are followed by tee.
But after add a same pipeline to capture another sensor, I can get 25fps from the appsink/fakesink with 2 app-bins;I can get only 21fps from the appsink/fakesink with 3 app-bins;and get only 17fps with 4app-bin. As app-bin and queue increase, the number of captured frames decreases.
I found that the function NvBufferTransform will cost much time when capture by using two cameras.
The following figure was work by using single camera.
