This is needed for cross-compiling without a build machine compiler
available. The option was added in 0.54, but we only need this in
Cerbero and it doesn't affect older versions so it should be ok.
Will just cause a spurious warning.

The --ref option indicate the size of the DPB, hence should be in the range of
0 to 16. This patch also fix the default to match x264enc default 3. This
change isn't a behaviour change since we don't enforce the reported default.
It's needed by the dvdread plugin but also by the x264 plugin in certain
circumstances. As it's part of GLib and always available, simply move it
as a hard dependency to the top-level meson.build.
It's technically true but not for this specific type.

Otherwise we get some compiler warnings:
../subprojects/gst-plugins-ugly/ext/x264/gstx264enc.c:200:1: warning: ‘unload_x264’ defined but not used [-Wunused-function]
unload_x264 (GstX264EncVTable * vtable)

load_x264 (const gchar * filename)
^~~~~~~~~
Avoid switch/case per frame for format decision and detect the format
only if where it could be changed. Note that, whenever encoder->input_state
is changed, gst_x264_enc_init_encoder() is called.

libx264 used to be built for one specific bit depth, and if we
wanted to support multiple bit depths we would have to dynamically
load the right .so from different paths. That has changed now, and
libx264 can include support for multiple depths in the same lib,
so we don't need to do the dlopen() dance any more. We'll keep
the vtable stuff around until we can drop support for older x264.

VUI(Video Usability Information) parameters should be set
according to the specification. However, some of the existing
hardware decoders refuse to decode in certain combinations of
the resolution and VUI parameters. To support the legacy
decoders, this patch provides 'insert-vui' to skip the settings.

LIBCDIO_VERSION_NUM was defined as e.g. 94 for 0.94 but is now defined
as 1 for 1.0. We had various checks for < 83, which of course succeeded
now although we are >= 0.83.
Fix this by checking for < 76 (0.76) too, as that is the minimum version
we currently support and everything < 76 is going to be >= 1.0.

Move creation of supported sink pads into class_init function
which is also the only place where they're used. Unref the
caps when no longer needed, the pad template will take its
own ref.
