Frame acquisition hangs after setting ROI #3

Closed dmyersturnbull closed 6 years ago

On our Allied Vision Pike 145B, we can capture still frames in format 0, mode 7 using Camera.start_one_shot and Camera.dequeue(poll=True).

However, setting image_size = (4*100, 2*100) where the width and height are multiples of their respective units and less than max_image_size, Camera.dequeue(poll=True) hangs permanently.

Camera.dequeue also hangs if we use start_video or start_multi_shot, even if we don't set the ROI.

Hmm. It is a bit unlikely that this is is a pydc1394 problem. My guess would be that this is also in bare dc1394 or/and the format being invalid or requiring a different triggering mode (maybe a hardware trigger).

Is this resolved?
