RZ-V2H unable to capture camera data using sample app for second camera (/dev/video1fr)

Question

Hi , 
 
 2 cameras are connected to RZ-V2H which are enumerated as " /dev/video0fr " and "/dev/video1fr" as described in document RZ/V2H ISP Support Package Sample Application Note R01AN7210EJ0110.pdf. 
 
 1) execute sample-app for /dev/video0fr , i am able to see the captured 8 frames dumped in /tmp directory. 
 2) executing sample application using below command for "dev/video 1 fr" it fails to provide any output and no error is seen in the command prompt. 
 Sample application program seems to be running infinitely and no output in seen /tmp directory. Please guide on possible cause. 
 root@rzv2h-evk-ver1: ~ # ./sample-app /dev/video1fr sample-app v1.1.1 output_mode = 0 port = 22222 output_prefix = [/tmp/] fps = 30, network_fps = 1 width = 3840, height = 2160, fourcc = [YUY2] 8 buffer, 8 frames, batch_mode = 0, nb_buffer = 8 one_frame_length 16588800 
 
 Regards,

Hi chekr, Can you please try /dev/video1fr with gstreamer? You can take a look on this RZ/V2H Group and RZ/V2N Group Linux Interface Specification GStreamer User's Manual: Software Appendix D How to Detect Active Camera. Kind Regards.

One point the Camera Vendor CSM.SOL has the camera driver configured as master slave. So the slave camera cannot run with out the master running. Please try the both gstreamer commands. 
 
 gst-launch-1.0 v4l2src device=/dev/video0fr ! waylandsink -v position-x=0 position-y=550 out-w=960 out-h=540 & \ 
 gst-launch-1.0 v4l2src device=/dev/video1fr ! waylandsink -v position-x=960 position-y=550 out-w=969 out-h=540 & This will start both cameras. 
 Also you need to run the v4l2-init.sh script first.
