I want to display captured frames from a webcam. I am using video4linux2, v4l2 bindings for python and ctypes.
I am also using Tk. In the main loop of my v4l2 app, after Q_BUF, STREAM_ON, DQ_BUF I call method that looks something like that: window = Tkinter.Tk() image = ImageTk.PhotoImage(pixelfmt, (320, 240)) label = Tkinter.Label(window, image=image) label.pack() im = Image.frombuffer(pixelfmt, (320, 240), ctypes.string_at(buf.userptr, buf.length), 'raw', pixelfmt, 0, 1) image.paste(im) window.update() Now, how is buf.userptr supposed to look like? A ctypes.c_void_p? In my case buf.userptr is long. Something like 170692608. I don't know how addresses in python should look like. _______________________________________________ Image-SIG maillist - Image-SIG@python.org http://mail.python.org/mailman/listinfo/image-sig
