e7544dc57e vaapipostproc: add initial support for scaling.
Add initial support for basic scaling with size specified through the
"width" and "height" properties. If either user-provided dimension is
zero and "force-aspect-ratio" is set to true (the default), then the
other dimension is scaled to preserve the aspect ratio.

cf69e7269c vaapipostproc: add initial support for color conversion.
If VPP is available, we always try to implicitly convert the source
buffer to the "native" surface format for the underlying accelerator.
This means that no optimization is performed yet to propagate raw YUV
buffers to the downstream element as is, if VPP is available. i.e. it
will always cause a color conversion.

d71008210d vaapipostproc: factor out operations to be applied into flags.
Even if we only support deinterlacing for now, use flags to specify
which filters are to be applied to each frame we receive in transform().
This is preparatory work for integrating new filters.

ae5e5be80b vaapipostproc: add support for raw YUV video source buffers.
Allow video processing from raw YUV buffers coming from the sink pad,
while still producing a VA surface for the downstream elements.

f6f24bfc55 vaapipostproc: rework plug-in element.
Rewrite the vaapipostproc plug-in element so that it derives from
GstBaseTransform, thus simplifying the caps negotiation process.

944a7bd077 filter: add initial support for deinterlacing.
Add basic deinterlacing support, i.e. bob-deinterlacing whereby only
the selected field from the input surface is kept for the target surface.
Setting gst_vaapi_filter_set_deinterlacing() method argument to
GST_VAAPI_DEINTERLACE_METHOD_NONE means to disable deinterlacing.

Also move GstVaapiDeinterlaceMethod definition from vaapipostproc plug-in
to libgstvaapi core library.

4cf44e3ad2 plugins: integrate GstVaapiVideoBuffer from libgstvaapi.
Move GstVaapiVideoBuffer from core libgstvaapi decoding library to the
actual plugin elements. That's only useful there.

79b45a43d1 Do not forward declare enums.
Forward declaring enums is not allowed by the C standard and aborts
compilation if the header file is included in a C++ project.

ba3ae60613 plugins: declare _get_type() functions as const.
Declaring a function as const enables better optimization of calls to
the function.

894d65b81a vaapipostproc: add new element for video postprocessing.
Add vaapipostproc element for video postprocessing. So far, only basic
bob deinterlacing is implemented. Interlaced mode is automatically
detected based on sink caps ("interlaced" field).
