Decklink 3D capture stops working after 120 frames

PostTue May 07, 2019 12:24 pm

Hi,

We have a problem trying to capture dual independant SDI streams using the newer version 11.1 driver and SDK with a few diifferent cards ranging from the 4K Exreme through to the 8K Pro.



Using the EnableVideoInput configuration flag, bmdVideoInputDualStream3D, SDK 3D capture stops after roughly 120 frames no matter what dual input mode. The callback to VideoInputFrameArrived just stops happening, no errors seem to be generated? The same code path works for single stream capture.

The previous build of our software with the 10.7 SDK was working fine, but we want to utilise the newer SDK for 8K card support.

Media express does not have the problem setting the flag and capturing.

Anybody have any idea what is going wrong?

Thanks for you help in advance,

Darren

Hi,

This issue has been relsoved thanks to Cameron @ Blackmagic. Basically, when you ask for a right eye frame from the threeDExtension interface you must release it. Does say this in the SDK, so user error.
