3b714c8913 context: move overlay composition to separate files.
Move GstVideoOverlayComposition handling to separate source files.
This helps keeing GstVaapiContext core implementation to the bare
minimal, i.e. simpy helpers to create a VA context and handle pool
of associated VA surfaces.

c85b080688 context: clean-ups. Strip down APIs.
Improve documentation and debug messages. Clean-up APIs, i.e. strip
them down to the minimal set of interfaces. They are private, so no
need expose getters for instance.

c5bdeb6980 libs: check that private headers remain private.
Make sure that libgstvaapi private headers remain internally used to
build libgstvaapi libraries only. All header dependencies were reviewed
and checks for IN_LIBGSTVAAPI definition were added accordingly.

Also rename GST_VAAPI_CORE definition to IN_LIBGSTVAAPI_CORE to keep
consistency.

ed302d091e Bump library major version.
Bump the library major version due to API/ABI changes that occurred in
the imaging API. In particular, GstVaapiDisplay interfaces no longer
expose any GstCaps but provide GArray based ones e.g. to determine the
set of supported decode/encode profiles.

When decoding failed, or that the frame was dropped, the associated

Round down the calculated, or supplied, bitrate (kbps) into a multiple

that to have less losses in precision. Likewise, don't round up because
that could be a strict constraint imposed by the user.

before the pipeline has been set to PLAYING, the display has not yet
