Grab single image with jit.qt.grab - strange delay
Hi,
I am very new to Max and Jitter and this is my first post here.
I am trying to grab still images with my webcam (built-in on macbook) and the jit.qt.grab object and have run into a strange problem I cannot get my head around:
The first two bangs I send to jit.qt.grab results in a black screen in my jit.pwindow. My third bang displays an image but it is the image grabbed on the second bang.
I have tried added print objects comming from both the jit.qt.grab and jit.pwindow objects and they show up in the max window so it looks like my flow is correct.
I am sure it it something simple but being a Jitter noob my debugging skills are not so good yet. Any help is appreciated.
You are sending one bang to tell jit.qt.grab to grab a frame. The next bang grabs a new frame and outputs the old to the pwindow. So I guess you could try to image the frame sitting in jit.qt.grab, waiting to be pushed out by the next grabbed frame, or something like that...
Aha I see - thank you for the explanation. Will try to figure out what to do from here, follow up questions are very likely
Thanks again.
