No callback on software trigger in C++

[mbcel]

I am using the tcamcamera.cpp class from the examples to get an image on software trigger. For this I am initializing the camera as follows:

std::shared_ptr<gsttcam::Property> exposureProperty = tcamCamera.get_property("Exposure Auto");
exposureProperty->set(tcamCamera, "Off");
std::shared_ptr<gsttcam::Property> whitebalanceProperty = tcamCamera.get_property("Whitebalance Auto");
whitebalanceProperty->set(tcamCamera, "Off");
std::shared_ptr<gsttcam::Property> gainAutoProperty = tcamCamera.get_property("Gain Auto");
gainAutoProperty->set(tcamCamera, "Off");
std::shared_ptr<gsttcam::Property> triggerModeProperty = tcamCamera.get_property("Trigger Mode");
triggerModeProperty->set(tcamCamera, "On");

then I trigger with:

std::shared_ptr<gsttcam::Property> triggerProperty = tcamCamera.get_property("Software Trigger");
triggerProperty->set(tcamCamera, true);

and no callback is received. With normal live feed the callback receives images normally. I am using the aravis driver.

What am I doing wrong?

Hi,

The code segments you posted appear to be correct. What camera model are you using? Knowing that I can try an reproduce this issue.

Does software trigger work when using tcam-capture? I am asking because that way we will know that there are no other issues preventing your code from working.

Aren't you missing the "Trigger Source" Property? I think it should be set to Software for software triggering.

//g_value_set_string(&str, "Line1"); g_value_set_string(&str, "Software"); cameraInst->set_property("Trigger Source", str);
