General Idea:
=============
_____/ gstv4lsrc.[ch]
_____/ \ v4lsrc_calls.[ch]
/
gstv4lelement.[ch] _/____________/ gstv4lmjpegsrc.[ch]
v4l_calls.[ch] \ \ v4lmjpegsrc_calls.[ch]
\_____
\_____/ gstv4lmjpegsink.[ch]
\ v4lmjpegsink_calls.[ch]
I.e., all the files on the right are child classes of
the v4lelement 'parent' on the left.
* v4lelement handles generic v4l stuff (picture settings,
audio, norm/input setting, open()/close())
* v4lsrc, v4lmjpegsrc handle the capture specific
functions. Maybe we'd need a v4lmpegsrc too
* v4lmjpegsink handles mjpeg hardware playback of video
