d8f0deadc3 deinterlace: Split out NULL checks in yadif
Separate out explicit NULL checks for fields we depend on so
that coverity can hopefully verify dependencies better.

1106eb16b6 deinterlace: Handle NV12/NV21 for the greedyl mode.
Don't fall back on the default interpolate_scanline function, which
blindly tries to copy from the next field, which can be NULL in
mixed progressive/interlaced streams

5fce46f5ef deinterlace: Call the planar functions for the Y plane of nv12/nv21
In some algorithms (like yadif), the Y plane has to be handled different
than the UV plane. Therefore, the planar_y functions are now called for
the Y plane, and the nv12/nv21 functions are handling only the UV/VU
planes respectively.

1c1bc56a3b deinterlace: Allow for 5 fields for interpolation
Add an extra field to the simple deinterlace implementation,
so that methods can potentially use 5 fields - the current
field, and 2 before and 2 after.

5468988223 deinterlace: Force renegotiation when changing mode
Switching the deinterlacing mode on-the-fly from disabled to
auto used to work, but was broken by commit #1f21747c some
years ago.

Force re-negotiation with downstream when the mode or
fields properties are changed, otherwise deinterlace
never switches out of the passthrough mode.

dba90631bc deinterlace: Fix field ordering for reverse playback

b09f478e80 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

it breaks negotiation in pipelines like:

3738ce8ba1 deinterlace: remove check for impossible condition
Commit bd27a1f30b added a few error handling
memory management checks. These check srccaps to see if it needs to be
unreferenced before returning, in the case of invalid_caps this goto jump
always happens before srccaps is set, so it will always be NULL in this
error label.

bd27a1f30b deinterlace: Do passthrough in auto mode if downstream only supports interlaced
If the following conditions are met:
1) upstream and downstream caps are compatible
2) upstream is interlaced
3) downstream doesn't support progressive mode
then deinterlace will just do passthrough instead of failing to link.

This is done with the following scenario in mind:

videotestsrc ! "video/x-raw,interlace-mode=interleaved" ! deinterlace
name=dein_src ! tee name=t ! queue ! deinterlace name=dein_file ! filesink t. !
queue ! deinterlace name=dein_desktop ! autovideosink
In this case, dein_src will do the deinterlacing. However,

videotestsrc ! "video/x-raw,interlace-mode=interleaved" ! deinterlace
name=dein_src ! tee name=t ! queue ! deinterlace name=dein_file ! filesink t. !
queue ! deinterlace name=dein_desktop ! autovideosink t. ! queue !
"video/x-raw,interlace-mode=interleaved" ! fakesink

In this case, caps auto-negotiation will make dein_file and dein_desktop do
the deinterlacing, while dein_src will be passthrough.

46735f8de9 deinterlace: Add mode=auto-strict
In this mode we will passthrough all progressive caps but interlaced caps must be
caps where we actually support deinterlacing.

This is the only difference between auto and auto-strict, auto would
passthrough all unsupported interlaced caps.

8c1c091439 deinterlace: Rewrite caps negotiation
Previously the result of the CAPS query and ACCEPT_CAPS depended on what kind
of caps were last set, and e.g. if we last had interlaced caps or not. That's
just broken.

Also previously the handling of non-sysmem caps features was rather random and
unusuable.

Now the behaviour is the following, depending on the mode property:
1) mode=disabled
  Completely do passthrough of everything
2) mode=interlaced
  Only accept formats we can actually deinterlace, and accept interlaced
  and progressive content and always run the deinterlacer and output
  progressive content
3) mode=auto (i.e. playbin)
  Accept all progressive formats as passthrough, accept all formats that we
  can deinterlace ourselves (which we do then), but also accept everything
  else for which we then just passthrough. In auto mode, deinterlacing is best
  effort: If we can, we deinterlace, if we can't we just output interlaced
  content.

82d62b9edd deinterlace: implement accept-caps
Implement accept-caps handler to avoid doing a full caps query
downstream to handle it.

This commit implements accept-caps as a simplification of the _getcaps
function, so it exposes the same limitations that getcaps would.
For example, not accepting renegotiation to caps with capsfeatures when
it was last configured to a caps that it has to deinterlace.
