jit.grab working with Decklink Mini, but not with Decklink Duo 2
Apr 06 2021 | 9:48 pm
First post, hello everyone! Also, new to Max MSP. Please be kind : ) I have this weird problem with my Blackmagic Capture Cards. I have in the same PC a Decklink Mini (1 Channel SDI) and a Decklink Duo 2 (4 Channel SDI). Just working with the help example for jit.grab, I'm able to get a 1080p25 camera input via jit grab from the Decklink Mini, using the [native] driver. If however I plug the exact same signal into the Decklink Duo 2, and select its [native] driver, jit.grab throws this error message:
jit.grab: blackmagic device unable to find valid video input format - closing stream
I've tried to pick the video format manually to no avail. With the Mini, the format is just selected automatically. I'm using BM Video Desktop 12.0 and the latest firmware, as well as the latest version of Max. Would be grateful for any ideas or pointers!
