d4f00383ed unify caps template for VAAPI encoders and decoders
There is no difference in VAAPI surface caps between encoders and decoders.
Thus, the patch makes a simplification by removing encoders specific caps and
shares the same definition of VAAPI surfaces caps for all the elements.

77ddde41d9 rename encoders to vaapi{codec}enc
Trying to comply with GStreamer's element names, this patch renames the
encoders using the name format vaapi{codec}enc.

In this way, the plugin documentation is linked correctly.

66f05af288 refactor vaapi caps strings for pad templates
Refactor the main vaapi caps strings into three macros:
GST_VAAPI_MAKE_SURFACE_CAPS, GST_VAAPI_MAKE_ENC_SURFACE_CAPS and
GST_VAAPI_MAKE_GLTEXUPLOAD_CAPS.

Those are in gstvaapipluginutil.h so all the elements could use them, instead
of re-declaring them every time.

No functional changes.

8b36e25f47 Removal of gstreamer-1.0 support
The support for GStreamer 1.0 has been obsoleted in 0.5.10 release.
GStreamer 1.2 is the a minimal requirement for building the gstreamer-vaapi.

This patch removes all the pre-processor conditional code compilation guarded
for gstreamer-1.0.

Thus, all the video converters were removed too.

c561b8da8a update and move gstcompat.h
The purpose of gstcompat.h is to couple the API differences among
gstreamer-1.0 and gstreamer-0.10. Since gstreamer-0.10 is obsolete, the code
in this compatibility layer shall be removed.

Nevertheless, the gstcompat.h header should be kept, if new incompatibilites
appear in the future, but it shall live in gst/vaapi, not in gst-libs.

This patch removes the crumbs defined gstcompat.h and moves it to gst/vaapi.
In order to avoid layer violations, gstcompat.h includes sysdeps.h and all
the includes in gst/vaapi of sysdeps.h are replaced with gstcompat.h

7f3795c9fb encode: Attach the codec-data to out caps only based on negotiated caps
Attach the codec_data to out_caps only if downstream needed.
For eg: h264 encoder doesn't need to stuff codec_data to the
src caps if the negotiated caps has a stream format of byte-stream.

7bdf3fa177 encoder: h264: add initial support for H.264 Stereo High profile.
Add initial support for Subset SPS, Prefix NAL and Slice Extension NAL
for non-base-view streams encoding, and the usual SPS, PPS and Slice
NALs for base-view encoding.

The H.264 Stereo High profile encoding mode will be turned on when the
"num-views" parameter is set to 2. The source (raw) YUV frames will be
considered as Left/Right view, alternatively.

Each of the two views has its own frames reordering pool and reference
frames list management system. Inter-view references are not supported
yet, so the views are encoded independently from each other.

bdf91aa765 encoder: h264: allow target decoder constraints.
Allow user to precise the largest profile to use for encoding due
to target decoder constraints. For instance, if CABAC entropy coding
mode is requested by "constrained-baseline" profile only is desired,
then an error is returned during codec configuration.

Also make sure that the suitable profile we derived actually matches
what the HW can cope with.

449ac54348 vaapiencode: fix negotiation process of output caps.
The specified caps in gst_video_encoder_set_output_state() function
arguments should not contain any resolution, pixel-aspect-ratio,
framerate, codec-data et al. Those rather should be set through the
returned GstVideoCodecState. This means that output caps creation
could be delayed until before gst_video_encoder_finish_frame() is
called.

This greatly simplifies the GstVideoEncoder::set_format() callback
by the way.

a43d06dcf5 vaapiencode: update for new properties API.
Update MPEG-2 and H.264 encode elements to cope with the new core
libgstvaapi properties API. i.e. all configurable properties are now
directly handled at the GstVaapiEncoder level.

Besides, this also makes sure to not use or modify the GstVaapiEncoder
private definitions directly. Private data need to remain private.

70b3600f11 encoder: add bitrate API.
Add gst_vaapi_encoder_set_bitrate() interface to allow the user control
the bitrate for encoding. Currently, changing this parameter is only
valid before the first frame is encoded. Should the value be modified
afterwards, then GST_VAAPI_ENCODER_STATUS_ERROR_OPERATION_FAILED is
returned.

error ("operation-failed") is issued.

d759fe34e6 vaapiencode: move common properties to base class.
Move "rate-control" mode and "bitrate" properties to the GstVaapiEncode
base class. The actual range of supported rate control modes is currently
implemented as a plug-in element hook. This ought to be determined from
the GstVaapiEncoder object instead, i.e. from libgstvaapi.

VA-API plug-ins.

84af151796 vaapiencode: fix support for raw YUV sink buffers.
Allow vaapiencode plug-in elements to encode from raw YUV buffers.
The most efficient way to do so is to let the vaapiencode elements
allocate a buffer pool, and subsequently buffers from it. This means
that upstream elements are expected to honour downstream pools.

If upstream elements insist on providing their own allocated buffers
to the vaapiencode elements, then it possibly would be more efficient
to insert a vaapipostproc element before the vaapiencode element.
This is because vaapipostproc currently has better support than other
elements for "foreign" raw YUV buffers.

f1c33feef9 plugins: add h264 encoder element.
Add GstVaapiEncodeH264 element object. The actual plug-in element
is called "vaapiencode_h264".

Valid properties:
- rate-control: rate control mode (default: none)
- bitrate: desired bitrate in kbps (default: auto-calculated)
- key-period: maximal distance between two key frames (default: 30)
- num-slices: number of slices per frame (default: 1)
- max-bframes: number of B-frames between I and P (default: 0)
- min-qp: minimal quantizer (default: 1)
- init-qp: initial quantizer (default: 26)
