Audio capture issues - Studio 4k
Posted: Mon Apr 10, 2017 3:54 pm
Hello, I'm Erick Monteiro from the company FPF Tech in Manaus, Amazonas in Brazil.
We are developing an application in LabVIEW (Windows) which tests set-top boxes and we need to acquire video and audio from different inputs (HDMI, CVBS and Component)
For video data, we had no problem in getting the images but we couldn't acquire the audio data properly. We tried to capture audio data using the same process we use when capturing data from microphone but when we checked the recording devices, the device Blackmagic Audio 4k was stated as "Currently unavailable" so we thought that it needs some enabling process before recording.
Also, as we are checking different inputs, it's not good for the test automation that we manually use the Blackmagic Setup to change the audio and video inputs, if there's any way of changing via SDK or some DLL, please inform us.
Thanks,
Erick Monteiro
