Ronald S. Bultje c626afd60a sys/v4l/v4lsrc_calls.c: Don't actually error out if we get another return value than 
Original commit message from CVS:
* sys/v4l/v4lsrc_calls.c: (gst_v4lsrc_try_capture):
Don't actually error out if we get another return value than
-EINVAL. Opposite to what I first thought, drivers have random
return values for this, although -EINVAL is the expected return
value. Since this is not fatal, we shouldn't use
GST_ELEMENT_ERROR() but just GST_ERROR_OBJECT().

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
