Error :

libdc1394 error: Failed to initialize libdc1394

We don’t need to use camera hardware, is there perhaps a way of compiling without that part of OpenCV or If the server is in VBox/Virtualization system simply enable USB controller.
If it is remote server and we don’t need camera hardware you can create the null link for the IO dev.

 sudo ln /dev/null /dev/raw1394
