06c7fde8e0 filter: fix semantics of deinterlacing flags.
Fix deinterlacing flags to make more sense. The TFF (top-field-first)
flag is meant to specify the organization of reference frames used in
advanced deinterlacing modes. Introduce the more explicit flag TOPFIELD
to specify that the top-field of the supplied input surface is to be
used for deinterlacing. Conversely, if not set, this means that the
bottom field of the supplied input surface will be used instead.

b62bd57bda vaapipostproc: fix support for raw YUV data upload on GStreamer 1.0.
Fix raw YUV data uploaded as in the following pipeline:
$ gst-launch-1.0 filesrc video.yuv ! videoparse ! vaapipostproc ! vaapisink

The main reason why it failed was that the videoparse element simply
allocates GstBuffer with raw data chunk'ed off the sink pad without
any prior knowledge of the actual frame info. i.e. it basically just
calls gst_adapter_take_buffer().

We could avoid the extra copy performed in vaapipostproc if the videoparse
element was aware of the downstream pool and bothers copying line by
line, for each plane. This means that, for a single frame per buffer,
the optimizatin will be to allocate the video buffer downstream, map
it, and copy each line that is coming through until we need to fills
in the successive planes.

Still, optimized raw YUV uploads already worked with the following:
$ gst-launch-1.0 videotestsrc ! vaapipostproc ! vaapisink

cc055b72ce vaapipostproc: try to downgrade deinterlace-method when needed.
If the currently selected deinterlacing method is not supported by the
underlying hardware, then try to downgrade the method to a supported one.
At the minimum, basic bob-deinterlacing shall always be supported.

be7a2ed64c vaapipostproc: add initial support for deinterlacing with VPP.
Allow basic bob-deinterlacing to work when VPP is enabled. Currently,
this only covers bob-deinterlacing when the output pixel format is
explicitly set.

2aab27b8de vaapipostproc: fix build on 64-bit platforms with GStreamer 0.10.
The size argument for GstBaseTransform::transform_size() hook is a
guint in GStreamer 0.10 APIs but a gsize in GStreamer >= 1.0.X APIs.

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.

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.

6b259abc02 vaapipostproc: fix reference counting buf for passthrough mode.
Fix reference counting bug for passthrough mode, whereby the input buffer
was propagated as is downstream through gst_pad_push() without increasing
its reference count before. The was a problem when gst_pad_push() returns
an error and we further decrease the reference count of the input buffer.

38d84d968e plugins: initial port to GStreamer 1.0.
Port vaapidecode and vaapisink plugins to GStreamer API >= 1.0. This
is rather minimalistic so that to test the basic functionality.

Disable vaapiupload, vaapidownload and vaapipostproc plugins. The latter
needs polishing wrt. to GStreamer 1.x functionality and the former are
totally phased out in favor of GstVaapiVideoMemory map/unmap facilities,
which are yet to be implemented.

a00ae0918a plugins: cope with new GstVaapiVideoMeta API.
Update plugin elements with the new GstVaapiVideoMeta API.

This also fixes support for subpictures/overlay because GstVideoDecoder
generates a sub-buffer from the GstVaapiVideoBuffer. So, that sub-buffer
is marked as read-only. However, when comes in the textoverlay element
for example, it checks whether the input buffer is writable. Since that
buffer read-only, then a new GstBuffer is created. Since gst_buffer_copy()
does not preserve the parent field, the generated buffer in textoverlay
is not exploitable because we lost all VA specific information.

Now, with GstVaapiVideoMeta information attached to a standard GstBuffer,
all information are preserved through gst_buffer_copy() since the latter
does copy metadata (qdata in this case).

7a0382130f configure: drop check for --enable-vaapi-glx.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.

Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.
