Decklink SDK 12.1 / OpenCV
Posted: Thu Sep 30, 2021 2:09 pm
I'm trying to get a few examples running , however it seems some of them have not been updated for SDK 12.1.
Specifically the "Advanced Video Playback and Capture" as well as the "OpenCV examples."
I can get the OpenCV face tracking app to compile ( after changing the HAAR classifier for opencv-4.5.3 ) , and changing the location of the Classifier XML files ( otherwise there is just an unhelpful exception ... ).
I've changed the input mode to 1080p50 for my source signal.
I am using a Quad 2 , and have the InputLoopThrough and the OpenGL examples working.
BUT the OpenCV example appears to capture a single frame and perform face tracking on that single frame. The identified face rectangle is sent to the output SDI - but frame capture stalls.
I don't see a ScheduledFrameCallback event almost as though the output playback hasn't been scheduled.
Any help fixing the OpenCV example would be greatly received. As well as updating the capture example to 12.1.
