c9597298f9 docs: remove outdated and pointless 'Last reviewed' lines from docs
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

7c006edf8d osxvideosink: Set rank to MARGINAL
If available we prefer using glimagesink over osxvideosink. It supports
more formats and in general has more features than osxvideosink.

e5ef2db489 v4l2: Fix support for caps without width, height, framerate or format
For format like mpegts, width and height is rarely in the negotiated caps. This
patch fixes failure when setting format, and prevent introducing width, height,
framerate and format to the caps when fixating.

517f50f54f v4l2src: Fix support for mpegts streams
It seems that GStreamer's mpegts elements (tsdemux, tsparse) require caps
`video/mpegts,systemstream=true`.  As far as I can see the significance
of systemstream is to indicate that this is a container format rather than
an elementary stream.  As this is the case (and I can't understand how it
could not be the case with mpegts) I add systemstream=true to v4l2src's
caps.

This allows v4l2src to be linked with tsdemux for playback from my
Hauppauge HD-PVR with the pipeline:

    v4l2src ! queue ! tsdemux ! video/x-h264 ! decodebin ! xvimagesink

In combination with the next commit this fixes using Hauppauge HD-PVR with
GStreamer 1.0+.

155d666845 v4l2: Add types compatiblity for other OS
Adds type compatiblity with other OS like BSD. This uses types mapping macro to
avoid conflict with existing defined types. We resuse glib types as these are
already available on supported platforms. This is GCC only because of the
le32 type that uses bitwise attribute.

478c9578f7 v4l2: Actually build the plugin
The checks were removed inadvertedly in previous patch and not replaced.
Re-introduce the configure checks and some of the checks in order to enable
this plugin again. We only check if videodev2.h exist on the platform to
avoid building on Windows or OSX, though we build against our own copy. This
was breaking the build on built-bot.

418a4940a8 v4l2: Use a copy of videodev2.h header
With years the amount of ifdef have grown up and we are not even sure if the
old code path compiles. Each time we need to update the v4l2 framework to add
the new feature, we break compilation on older kernel. With exception of two
controls in the video orientation control, this patch get rid of all ifdef by
including the latest version of videodev2.h inside GStreamer.

d3bd3ecc3e v4l2: Normalise control names in the same way as v4l2-ctl
V4L2 kernel drivers allow configuration of the hardware settings via a
mechanism called controls.  These can be referred to by name such as
"Brightness" and "White Balance Temperature".  The user-space command line
client for setting these controls (v4l2-ctl) normalises these names such
that they only contain lower case alphanumeric characters and the
underscore '_'.  e.g:

    Kernel                     v4l2-ctl
    ----------------------------------------------------
    Brightness                 brightness
    White Balance Temperature  white_balance_temperature
    Focus (absolute)           focus_absolute

GStreamer seems to want to follow this pattern but failed for controls with
more than one consecutive non-alphanum character.  e.g. GStreamer would
produce "focus__absolute_" rather than "focus_absolute".

This commit fixes that issue.  Backwards compatibility is preserved by
normalising all control names before comparison.

b4820460d8 v4l2src: Flag interlaced buffers as interlaced.
We correctly indicate the field ordering on interlaced buffers, but fail to
flag them as containing interlaced video, which we need to do here because
we signal interlace-mode=mixed in our caps. This means that downstream
elements (like vaapipostproc from gstreamer-vaapi) don't recognise these
buffers as in need of deinterlacing.

Fix this by setting the interlaced flag on all interlaced buffers.
