First of all, we are offering this package for supporting our own camera, although we try to keep it as general as possible. So, I can try to help ...

Can you post the output of "gc_info 2F01F38YAK00044"?

heikohimu commented 5 years ago

It looks like AcquisitionStart is not ready (i.e. writable) at the time when gc_stream uses it. I also do not understand why AcquisitionStart is marked as NA in the output of gc_info. I can only guess ...

Can you replace CONTROL in tools/gc_stream.cc by EXCLUSIVE and recompile gc_stream. Does it make a difference?

Another possibility would be to add a sleep in front of the AqcuisitionStart command in rc_genicam_api/stream.cc. Maybe the camera needs some time before acquisition can be started.

dmccskylove commented 5 years ago

I've tested both of the methods you mentioned above. The same result. I also tested another camera, basler's acA2500-14gm, with the same results. The question that I can't understand is that I can capture images correctly in the Baumer example. Why can't almost the same operation be implemented? image image

dmccskylove commented 5 years ago

Another information，I try to get AccessStatus after called open. "NoAccess" returned. Are these two related? image

heikohimu commented 5 years ago

This is strange, because the gc_info output that you posted shows that the AccessStatus is ReadWrite. A difference is that gc_info prints the status without opening the device, while are requesting it after opening it. In any case, GenTL specifies that this information should be consistent. Thus, it should not matter if the device is open or not.

Actually, according to GenTL specification, "NoAccess" means "The device is seen by the producer but is not available for access because it is not reachable". Thus, it might be a networking problem. I can see in the gc_info output that a persistent IP was defined. Is the IP and subnet mask correct? On the other hand, if it works on the same computer with the Baumer software, then it should not be a networking problem.

Are you working under Windows? If yes, the Windows firewall might interfere. Can you switch it off, just for testing?

heikohimu commented 5 years ago

Have you checked network setup and firewall? Did it solve the issue?

dmccskylove commented 5 years ago

I am currently working in Ubuntu 16.04 environment. My understanding is that since the same configuration can work properly with other tools, it should be independent of the system environment. Ultimately, I used baumer's lib to solve the problem. Thank you for your valuable time.

heikohimu commented 5 years ago

Yes, it should be independent. Its just that the Windows firewall likes to interfere, but this is not the problem here.

wbt729 commented 5 years ago

I had the same issue as @dmccskylove using a Basler camera aCA 1300. What helped was to set TLParamsLocked=1. After this the AcquisitionStart truned from NA to RO:

` GenApi::IInteger lock=dynamic_cast<GenApi::IInteger>(parent->getRemoteNodeMap()->_GetNode("TLParamsLocked"));

lock->FromString("1");

GenApi::CCommandPtr start=parent->getRemoteNodeMap()->_GetNode("AcquisitionStart");
start->Execute();`
heikohimu commented 5 years ago

This is an interesting information. We do not use TLParamsLocked in our sensor, but it I guess it would not harm to implement it. I will do that.

luel1992 commented 4 years ago

I had a similiar issue and google search brought me here - I tried to get access to the Jumbo Frames (camera.GevSCPSPacketSize.SetValue(9000) ) but got the error --> _genicam.AccessException: Node is not writable. : AccessException thrown in node 'GevSCPSPacketSize' while calling 'GevSCPSPacketSize.SetValue()' (file 'integert.h', line 77)

with calling " camera.TLParamsLocked.SetValue(0) " before, (0! not 1) , I had no issues anymore and could modify the jumbo frames.

Access via python (pypylon) on a acA640-120gm

Maybe it will help other in the future
