First, what distribution are you using? If it's something recent, it's
probably using udev, which is a way for Linux to automatically create device
files when the system boots or when device driver configurations change. If
this is so and if you've just accidentally type "rm /dev/video0" or something
similar, you should get your device file back by rebooting the computer.
Assuming it's not that simple, you must have somehow configured your system to
not load the relevant driver. The fix will depend on how you did this, and
perhaps on what driver it is, and thus what hardware (particularly your
encoding device) you're using, so please post your hardware information. Some
clues about what you did to your backend in your experimentation would be
helpful, too; I can think of several very different ways you could have
caused your /dev/video0 device to go away, and the fixes will be equally
different.
