Camera.trigger(self) fails (calls non-existing execute_command)

[eudoxos]

Hi, thank you for your fantastic wrapper.

One issue in aravis.py:

    def trigger(self):
        """
        trigger camera to take a picture when camera is in software trigger mode
        """
        self.execute_command("TriggerSoftware")

however, execute_command is not defined.

Should this be perhaps replaced by calling self.cam.software_trigger() directly? Just guessing, unable to test at the moment.

probably an aravis API change. try to change it to self.dev.execute_command
Does that work? If so please send patch

[eudoxos]

That works, good :) Will do pull request soon. One more question, how do I retrieve the buffer afterwards? If I call pop_frame(), it waits forever.

[oroulet]

pop_frame waits for a new frame. probably som configuration with your camera. all cameras are differnts, want different parameters, etc

[eudoxos]

For the record, aravis already wraps software trigger as arv_camera_software_trigger, callable as aravis.Camera.software_trigger(). In internally executes SoftwareTrigger anyways.

If aravis camera object has it then you can call it from python camera object directly
