482d2c9459 interlace: Switch field-pattern on the fly 
The frame rate interlace uses changes when we change field-pattern, so
we need to issue a reconfigure event.

It would otherwise change the caps the element produces and cause the
element to misbehave

7c7ac7a0dc interlace: Don't fail negotiation if capsfilters decide framerate 
Try to negotiate if the framerates on either sides of the interlace are
decided using capsfilters and the framerates are correct. Otherwise the
following pipelines would fail to negotiate:

gst-launch-1.0 videotestsrc !
video/x-raw,framerate=24/1,interlace-mode=progressive ! interlace
field-pattern=2 ! video/x-raw,framerate =30/1 ! fakesink

gst-launch-1.0 videotestsrc !
video/x-raw,framerate=60/1,interlace-mode=progressive ! interlace
field-pattern=0 ! video/x-raw,framerate=30/1 ! fakesink

to top-field-first.

ba500b816a interlace: Only half the framerate for 1:1 field pattern 
Keep the framerate for 2:2 field pattern, and completely remove it from
the caps for all others. Otherwise, negotiation will fail if caps on
both sides of the element specify a framerate.

0c63c8d1f5 interlace: Add FIXME comment about false passthrough bug 
If interlace-mode is missing from upstream caps, we can falsely do
passthrough when in fact we'd have to switch fields.

969e647925 interlace: Fix crash with empty caps in setcaps 
If the src_peer_caps are EMPTY (e.g. negotiation failed somewhere), the
assertion inside gst_video_info_from_caps would fail and the whole
pipeline would crash. Check for gst_caps_is_empty before
gst_video_info_from_caps and gracefully fail if it's empty.

c67146b27a interlace: Increment phase_index before checking if we're at the end of the phase 
Incrementing it afterwards will always have to phase_index >= 1 and we
will never be at the beginning (0) of the phase again, and thus never
reset timestamp tracking accordingly.

This was broken in bea13ef43b in 2010, and
causes interlace to run into integer overflows after 2^31 frames or
about 5 hours at 29.97fps. Due to usage of wrong types for the integers
this then causes negative numbers to be used in calculations and all
calculations spectacularly fail, leading to all following buffers to
have the timestamp of the first buffer minus one nanosecond.

580a94d18b interlace: fix negotiation if filter caps are passed to query_caps 
Make videotestsrc ! interlace ! $anything work again. Problem
was that upstream filter caps were passed which contained
interlace-mode=progressive, which doesn't intersect too well
with interlace's source pad template caps, leading to
not-negotiated errors.

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).

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.
