Decklink changing output resolution sometimes fails

PostWed Jun 13, 2018 10:12 pm

Using a Decklink Duo 2. Code is in C#
I wrote a program that gets frames or audio and video from NDI. Let's say I'm getting 1080i 59.94 and outputting on channel 0. If the user changes source and the new source is a different resolution then currently used, sometimes EnableVideoOutput fails. If I use channel 1 then it's ok. And if I shutdown the output and try on channel 0 again, it will succeed. It almost looks like some sort of timing thing, where the Duo needs a bit of time to accept the new EnableVideoOutput. This little program is only getting 720p 59.94 and 1080i 59.94 so I know those are supported. I do the drill to check, but, of course that never fails. Any ideas?

Hi Russ,

Are you able to share your test application? Please can you send to the developer support email found in the Overview section of the DeckLink SDK Manual.
