Vizzie resolution of webcams

    Hi. I'm on OS X 10.13.13 with max 8. When I make a simple patch with grabbr going into a projectr , My webcam is logitech c920 (hd) why is my output so pixilated? It looks like 320x240. Examining the grabbr code it should be at least 1280x720. ??? thx

    • hi i had the same problem. you need to send a format message to jit.grab to set the desired resolution! you can see what i am talking about in the jit dx.grab helpfile. i wish the vizzie abstraction would implement this and the helpfile for jit.grab. hope this helps

    • thanks for the report. this is new behavior in the OS that changes the default format. we will look at ways to expose the format setting to the grabbr module.
      for now, you should be able to set the format with a jit.grab object, and the grabbr object will remember that format. the "Blackmagic" tab of the jit.grab help file demonstrates how to query and set the format.

    • OK thanks, I'll give it a try.

    • You're probably gonna say I'm being difficult, but can you stop changing things like this? Or when you change them, (in this case) make the default the highest quality format?

    • we didn't change anything. as mentioned above a change in OS behavior caused this.
      I have an open ticket to investigate defaulting to highest quality, but so far i have been unable to make it work consistently without manually changing the format attribute. Seems like it always eventually resets to the lowest quality.
