image_Transport_test branch: multiple cams trigger, error on timeout #18

Closed mithundiddi closed 5 years ago

mithundiddi commented 5 years ago

image_transport_test code works for single camera

when multiple cameras are plugged in, following error occurs

terminate called after throwing an instance of 'Spinnaker::Exception' what(): Spinnaker: Failed waiting for EventData on NEW_BUFFER_DATA event [-1011]

gdb output:

Tried with Powered USB hub, so it's not power related error either.

AcquisitionMultipleCamera binary, can save images from both the cameras.

The GetNextImage error occurs for the cam1 (for master cam, it is successful )before entering the loop in run_soft_trig()

Would also be interested in the resolution.

irispete commented 4 years ago

Was there a solution for this problem? I am encountering this same error when acquiring from multiple cameras

ghost commented 4 years ago

@irispete please start a new issue and fill out the details in the Bug Report so we can advise accordingly.

themightyoarfish commented 4 years ago

Don't know if it's applicable in this case, but this also happens when the available bandwidth is not enough. So if multiple cameras go over one 1gbit connection, you would need to set a non-debayered pixel format and debayer on the host, or retrieve a smaller sensor region.

themightyoarfish commented 4 years ago

Generally I've found this issue happens a lot when multiple cams are involved, even when they don't share a link, and one always has to permit retries, a timeout in GetNextImag() doesn't seem ro always work.

irispete commented 4 years ago

I created a new issue: https://github.com/neufieldrobotics/spinnaker_sdk_camera_driver/issues/75

irispete commented 4 years ago

@themightyoarfish forgive my ignorance, how do you permit retries?

themightyoarfish commented 4 years ago

By catching the exception and also calling GetImageStatus() and IsIncomplete() on the resulting frame. Sometimes, GetNextImage() succeeds but the frame is not useable.

In any event, I've had good experience with the FLIR support, though we are a business, so I can't say if they are this responsive for private individuals.
