Running "example_putImagetrans.cc" fails

[jameszhou12138]

Dear Unitree,

When I run "example_putImagetrans.cc" according to the tutorial in bilibili, it doesn't come up with the prompt [UnitreeCameraSDK][info] Load camera flash parameters OK!

unitree@unitree-desktop:~/UnitreecameraSDK$ ./bins/example_putImagetrans
[WARN:0] global /home/nvidia/host/build_opencv/nv_opencv/modules/videoio/src/cap_gstreamer.cpp(1757) handleMessage Opencv | Gstreamer warning: Embedded video playback halted; module v4l2srce reported: Internal data stream error.
[WARN:0] global /home/nvidia/host/build_opencv/nv_opencv/modules/videoio/src/cap_gstreamer.cpp(886) open Opencv | Gstreamer warning: unable to start pipeline
[WARN:0] global /home/nvidia/host/build_opencv/nv_opencv/modules/videoio/src/cap_gstreamer.cpp(480) isPipelinePlaying OpencV | Gstreamer warning: Gstreamer: pipeline have not been created

And I don't get the image from the camera...

Does anybody know how to fix the issue?

did you stop the camera related processes?
ps -aux | grep point_cloud_node | awk '{print $2}' | xargs kill -9
ps -aux | grep mqttControlNode | awk '{print $2}' | xargs kill -9
ps -aux | grep live_human_pose | awk '{print $2}' | xargs kill -9
ps -aux | grep rosnode | awk '{print $2}' | xargs kill -9

Yes, I did.
and I typed in the command ps -aux, the %CPU and %MEM of every process do not exceed 1.0

the another reason i believe the example can fail is because of the configuration in the "trans_rect_config.yaml" file, there are 3 specific configurations that can make the example not run properly:

1. ip of the reciever board (IpLastSegment), i use 15 to transfer to one of the nanos
2. DeviceNode (for example i use DeviceNode as 1 for the front camera in the head)
3. set Transmode to 2 worked for me
   So with this configuration i transfer the images from the front camera to the nano with ip finished with 15
   I hope this can help
