Stefan Kost 6e12954c68 video.c: use a break and a final warning instead of early returns 
Use breaks for case branches instead of return 0. We don't expect these to
happen anyway. Thus have a warning before the final return to make it easier to
see when things go out of sync.

Stefan Kost 40273cf2d3 video.c: use g_assert_not_reached() for logical error here. 
This will help to detect them closer to the source if they ever happen.

Thiago Santos 78e8b33c38 video: Getting component offsets without dimensions is fine if it is not YUV 
This fixes a regression that an assertion would happen if
gst_video_get_component_offset would be called with width or
height as 0.

Calling it with 0 is fine if the format isn't yuv and this
was already being used in some other places of video.c
