Errors after power on the camera

[zfxw0206]

I am using Ubuntu 14.04 and ROS indigo to run two pointgrey GigE blackfly cameras.
Now the problems is every time after I power on the cameras and run the "camera.launch" file, I always get the following error:

[ERROR] [1458741761.509388400]: PointGreyCamera::start Failed to start capture | FlyCapture2::ErrorType 22Could not get the current video mode and frame rate.

[ERROR] [1458741936.227051214]: PointGreyCamera::connect could not discover GigE packet_size | FlyCapture2::ErrorType 1Failed to discover GigE packet size

[ERROR] [1458741969.818965453]: PointGreyCamera::start Failed to start capture | FlyCapture2::ErrorType 33Error starting isochronous stream.

But when I tried to detect the cameras with rostopic "/diagnostics", I got nothing. I have to restart the launch, then it works fine. Does anybody could help me to fix these problems or tell me how to detect these errors? Thank you!

Hi, I cam across your issue just now. I don't know if you solved your problem.
Could you show us your launch file?

What happens if you do :
rosrun pointgrey_camera_driver list_cameras

You should get something like:
[0]Serial: xxxxxxxxx, Model: Flea3 FL3-U3-32S2C, Vendor: Point Grey Research, Sensor: Sony IMX036 (1/2.8" Color CMOS), Resolution: 2080x1552, Color: true, Firmware Version: 2.16.3.0
Of course this result is depending on the camera model you are using.

My problem is still there, here is my camera information:
[0]Serial: 16162102, Model: Blackfly BFLY-PGE-23S2C, Vendor: Point Grey Research, Sensor: Sony IMX136 (1/2.8" Color CMOS), Resolution: 1920x1200, Color: true, Firmware Version: 1.44.3.0

sudo sh -c 'echo 1024 > /sys/module/usbcore/parameters/usbfs_memory_mb'

[zfxw0206]

My camera is GigE camera, why set it to usbcore?

[bnjff]

Ah, sorry, I didn't notice it was GigE. Increasing usbfs memory limit solved "starting isochronous stream" error with USB3 camera.

Hi @zfxw0206 , were you able to solve the issue? I am facing a similar problem with a BlackFly BFLY-PGE-20E4C camera.

[sheelabhadra]

I didn't get the error anymore after I closed the FlyCapture application and ran the launch file in the terminal. I am using ROS Kinect by the way.

I got the same problem when run 'roslaunch pointgrey_camera_driver bumblebee.launch'

[ERROR] [1511783092.590248274]: Reconfigure Callback failed with error: PointGreyCamera::setFormat7 Format 7 mode not supported on this camera.

can anyone help?

[zfxw0206]

@sheelabhadra , I still have this issue, what I did is restarting the driver after getting the error, then the error disappeared.

[SubMishMar]

@sheelabhadra now I have this issue, can you please help me with this if you solved it somehow?

[fabrizioschiano]

@SubMishMar did you look at this : db22db0

Are you sure to be running the last version of the driver? (did you do a git pull and a catkin_make)

Also look here (just out of curiosity, to make sure you are not doing the same error): #162

[SubMishMar]

@fabrizioschiano I installed using sudo apt-get install, I dont think i need to git pull.. do I?

[fabrizioschiano]

@SubMishMar I am not sure, I don't think you need to do a git pull but just verify you have the following: db22db0

Maybe, the problem is somewhere else.
