Hi all,
I've noticed VIC supports up to 4 video devices on
Linux. VIC scans from /dev/video0 through /dev/video3
and the names of the device files are hard-coded into
the executable.
I need more device files because I have already over 4
video capture devices and want to use vloopback, which
consume 2 or more devicde files.
vloopback:

Of course, we can modify the source code of VIC and
compile it by ourselves. The file which has to be
modified is vic/video/grabber-video4linux.cpp. You will
find the following code:
/* here you can tune the device names */
static const char *devlist[] = {
"/dev/video0", "/dev/video1", "/dev/video2", "/dev/video3",
NULL
};
It will be nice that the VIC binary being distributed by
Rober Olson supports over 4 devices:
