Clément Bœsch 165bc9caa2 v4l2: make possible to disable libv4l2 at runtime.

usefulness of such library is mostly limited to backward compatibility

Giorgio Vazzana 785b849f1c lavd/v4l2: honor previously selected input channel
An input channel could have been previously set with another application, like
v4l2-ctl, so if no input channel is specified use the previosly selected one.

Allow to specify a filename where to put the filtergraph description.

This is useful to override limitations or glitches of particular shell

filtergraphs.
