I have connected a cam through firewire and tried to access it using opencv. The camera is detected in coriander and able to get a video stream. Below is the code I used
using namespace cv;
using namespace std;
cout<<"Camera not detected"<<endl;
cap >> frame;
When I run this code, the video is streamed from the webcam instead of my firewire cam. I tried the same code in my friend's system and there the firewire cam was detected. I tested the settings using different commands such as **testlibraw** , **lsmod** and they are all the same. Even the Opencv version, 2.4.9, Ubuntu 12.04 are all the same. This is really bizarre and am at this for 2 days. Can anyone please tell me what the difference could be? How can I get the external cam detected in opencv? Thanks in advance.
Note : Does this have something to have with setting the default cam? Thanks.
Update 1 : VideoCapture cap(1) gives the following error
HIGHGUI ERROR: V4L: index 1 is not correct!
Does this mean the camera is not recognized?
