View Full Version : unicap for stereo application

April 24, 2014, 20:24:36

I am trying to use unicap, in order to get stream from two different cameras. I have a DMM 22BUC03-ML and a DFM 22BUC03-ML.
So I made my own library to manage the parameters and the streams of the cameras.

I run the two camera separatly, it works properly but when I try to make it works at the same time, I get a smententation fault error.
This error appears when I run that command

if( !SUCCESS( unicap_start_capture( handle ) ) )

The handle object is link to each camera so I don't really anderstand why I get that error.

I try a stereo with DMM 22BUC03-ML and a webcam, and with this configuration there is no error.

Does anybody have already try to connect two imaging source camera?
Could someone give a reason a that segmentation fault?

Thanks in advance.

Best regard.

maybe the bandwidth of your USB controller is exhausted? You may lower the frame rate of the cameras or use two different USB controllers.

BTW: Unicap has an own forum and will be supported there.

Thank you for your response.

I will try to decrease the frame rate.

I don't find the official unicap librarie. What is the link of this forum?
