Don't fall back on the default interpolate_scanline function, which

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.

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.

f2c2560db2 deinterlace: Closed caption pass-through
Pass through closed caption data when deinterlacing. When two

data.

Also fixed memory leaks related to timecode meta pass-through.

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.

5d8e7598ac deinterlace: Fix typo to not change the input caps but our filtered caps
Changing the input caps and not using them anymore afterwards is useless, and
it breaks negotiation in pipelines like:

  deinterlace fields=all ! "video/x-raw,framerate=50/1,interlace-mode=progressive" !

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.
