... which is not particular relevant for audio parsing, but more so
in video cases.  In particular, auto-determine if dealing with video (caps).

e96b8a7b5f camerabin: Avoid assertion on image finishing 
As imgbin_finished() is scheduled from g_idle_add, it might
be run a little later than expected, this can lead to the application
setting camerabin to ready before imgbin_finished() runs. In this case,
the processing counter goes to 0 and an assertion happens.

This patch relaxes the imgbin_finished() check on the processing
counter.

0de362f248 interlace: Fix buffer timestamp and duration 
The field rate is twice the frame rate of the src pad and so the duration of
one output buffer is src_fps_d / (2 * src_fps_n).

341b0c2d62 interlace: Rename pattern property to field-pattern

bea13ef43b interlace: Add pattern offset property 
This property allows one to start at any point within the field pattern after
a discontinuity (whenever gst_interlace_reset () is called). Thus with the
2:3:3:2 pattern, for example, one can start at offset 2 and achieve 3:2:2:3
or offset 1 and achieve 3:3:2:2.

5c2f805199 camerabin: Create imagebin elements when image mode is set in camerabin NULL state 
This patch refactors imagebin element creation and linking into separate functions,
and adds re-using also for imagebin internally created elements.

So this refactoring allows creating imagebin elements already in NULL state when
application sets the image mode, and next state change from NULL to READY will be faster.
This reduces first capture latency.

Earlier the elements were both created and linked in NULL to READY state change.

8d5cfc6511 outputselector: Avoid losing the last_buffer when switching 
This patch makes outputselector take an extra ref when pushing
the last_buffer to avoid it losing it during the switch function.

This makes resend-latest properly work if the active-pad is changed
during the switch function buffer pushing (on a pad probe, for example).

and the section filter is not needed here and shouldn't be used at all
for these tables because the have a different structure.
For example, TDT tables were not parsed for odd hours because this bit
is the 'current_next_indicator' bit for the other sections, and the table
was discarded.
