While so far it worked, we are about to introduce a format that break this
assuming. We have a format which consist of NV12 with alpha, and this format
does not have a direct mapping of the component against their plane indexes.

Fix this by using gst_video_format_info_component() introduced in 1.18 for
this purpose.

e.g. if running a dual wgl/egl built library, then egl will always
succeed in creating the GstGLContext because almost anything could
support egl, as long as eglGetDisplay() works.

wgl, however has a check for the correct display type so should move
earlier in the tried list.

Allows more fine-grained control over the exact display type that is
created.

#865

Workaround for pkg.generate() escaping spaces in pc variables
that shouldn't be escaped. Perhaps going back to configure_file()
would be a better option though. Really needs a fix in Meson.

Improves throughput of the total convert and blend process and allows
for higher performance across slightly more threads.

Also make use of video aggregator's task pool for blending as well in
order to reduce the number of threads.

In case we already have a pad but more might be added later we were
ignoring the new pads added later, we should track the element
new pads and expose them as they are added.

New API:
- gst_gl_context_get_config()
- gst_gl_context_request_config()

A GL context configuration is a GstStructure that has some well-known
names for common values that can also be extended in platform-specific
ways if necessary.

Wrapped OpenGL contexts may be able to retrieve the GL context
configuration depending on the platform.  If that information is
available, GstGLContext will attempt to create an context that matches
the shared OpenGL context config unless gst_gl_context_request_config()
has been called.

A new environment variable 'GST_GL_CONFIG' will be read to influence the
configuration chosen.  The environment variable will only be used as a
fallback if gst_gl_context_request_config() has not been called.

opusdec have minimal conversion capability, adding the Converter class allow
gst-validate to behave properly and not spit an error when it notice that the
number of channels or rate miss-match in and out.

This meta hold one buffer of the same codec data as the parent memory. This
extra frame luma will be used as the alpha values for the final combined
frame. This is notably used to support VP8/VP9 alpha as defined in WebM and
matroska specification.

Otherwise real-time clock changes can wrongly trigger timeouts, or not
cause timeouts to happen in time.

Unfortunately real-time clock times still have to be kept track inside
the elements for the statistics. Switching those over to the monotonic
clock would cause behaviour changes from the application point of view.

The statistics are extended with fields with monotonic times though.

This allows dropping the newest or oldest buffer when the internal queue
is full instead of blocking or continuing to grow.

Part-of: <gstreamer/gst-plugins-base!1133>

These work the same way as the corresponding properties on queue and
allow to control the internal buffer size of the appsrc in a more
flexible way.

Unlike in queue the max-buffers and max-time properties are 0 (i.e.
disabled) by default for backwards compatibility reasons.

Instead of the deprecated gst_element_get_request_pad.

The return value is a list of GstElementFactory's that when

Cropping was not handled properly when frames have to be copied to
xvimage's buffer pool, first because the crop meta were dropped, and
second because the allocated frame size in xvimage's buffer pool were
smaller than the incoming frame.

This patch updates xvimagesink's video info when propose_allocation()
is called, and copies the GstVideoCropMeta from source frame to
destination one.
