a4d88db0fd plugins: preserve framerate when updating src caps video format.
In the current implementation, gst_video_info_set_format() would reset
the whole GstVideoInfo structure first, prior to setting video format
and size. So, coleteral information like framerate or pixel-aspect-
ratio are lost.

Provide and use a unique gst_video_info_change_format() for overcome
this issue, i.e. only have it change the format and video size, and
copy over the rest of the fields.

493337c4b1 vaapipostproc: add support for "download" capability.
Allow implicit conversions to raw video formats, while still keeping
VA surfaces underneath. This allows for chaining the vaapipostproc
element to a software-only element that takes care of maps/unmaps.
e.g. xvimagesink.

95d1826dca plugins: add helper for detecting VA surfaces in caps.
Introduce new gst_caps_has_vaapi_surface() helper function to detect
whether the supplied caps has VA surfaces. With GStreamer >= 1.2, this
implies a check for memory:VASurface caps features, and format=ENCODED
for earlier versions of GStreamer.

0607898019 vaapidecode: simplify bufferpool configuration.
Rework the logics behind the configuration of an adequate bufferpool,
especially when OpenGL meta or additional capsfeatures are needed.

Besides, for GStreamer >= 1.4, the first capsfeatures that gets matched,
and that is not system memory, is now selected by default.

5ffa82b64c vaapisink: add support for "display-name" property.
Add a "display-name" property to vaapisink so that the end user could
select the desired output. Keep "display-name" in-line with the existing
"display" (GstVaapiDisplayXXX type).

So, for X11 or GLX, the "display-name" is the usual display name as we
know for XOpenDisplay(); for Wayland, the "display-name" is the name used
for wl_display_connect(); and for DRM, the "display-name" is actually the
DRI device name.

dac20cecb4 plugins: expose I420 format for interop with SW elements.
Always expose I420 format by default when the VA surface could be
mapped for interoperability with non harware accelerated elements.
However, the default behaviour remains the auto-plugging of vaapi
elements, down to the sink.

Side effect: "direct-rendering" mode is also disabled most of the
times as plain memcpy() from uncached speculative write combining
memory is not going to be efficient enough.

ef9819ecf4 plugins: add helpers to create video caps with features.
Add gst_vaapi_video_format_new_template_caps_with_features() helper
function to add the supplied caps feature string on GStreamer >= 1.2.

Add gst_vaapi_find_preferred_caps_feature() helper function to discover
the "best" caps feature to use for the supplied pad. In practice, we
will always favor memory:VASurface first, then meta:GLTextureUploadMeta,
and finally the system memory caps.

Add thin compatibility layer for the deprecated GstVideoContext API.
For GStreamer API >= 1.2, this involves the following two functions:
- gst_vaapi_video_context_prepare(): queries if a context is already
  set in the pipeline ;
- gst_vaapi_video_context_propagate(): propagates the newly-created
  context to the rest of the pipeline.

f75762d910 plugins: initial port to GStreamer 1.2.
Port vaapidecode and vaapisink plugins to GStreamer API >= 1.2. This

Disable vaapipostproc plugin for now as further polishing is needed.
Also disable GstVideoContext interface support since this API is now
gone in 1.2.x. This is preparatory work for GstContext support.

b868c6d888 plugins: fix display type comparison in gst_vaapi_create_display().
After the code got moved to create the gst_vaapi_create_display() helper,
this comparison was not updated to dereference the newly-created
pointer, so the code was comparing the pointer itself to the type, and
therefore failing to retrieve the VA display.

This fixes the following error (and gets gst-vaapi decoding again):

    ERROR vaapidecode gstvaapidecode.c:807:gst_vaapidecode_ensure_allowed_caps: failed to retrieve VA display

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.
