hi,
how can i discover whether a video device /dev/video0 is support v4l or
v4l2? currently if i try to use the wrong type in gstreamer it's hang
forever and only a hard kill can help.
is there any way where can i find out the type?
thanks.

Do an VIDIOC_QUERYCAP ioctl on it if it supports that its v4l2, if not it is v4l1
