all the old GStreamer version guards.

A caps query can occur before the element has a display. In that case, the
element can return its pad's template. But when the element already has a
display, and the caps probe fails, the element shall return an empty caps, so
the auto-plug could try with another decoder.
If the element has a display and the caps probe works, then the computed caps
should be returned.

Caps query can happen before the element has a bus. The display creation should
be should occur on the context negotiation, when the bus is already configured.
Then at caps query no display should be created.
Instead of force the display creation, we graciously fail the allowed_caps()
creation.
This change only applies for vaapidecode and vaapisink. The vaapipostroc, as a
basetransform descendant, seems to be not affected by this, nor the encoders.

The current context query handling design is flawed: the function
gst_vaapi_reply_to_query() returns FALSE either if the query is not a
GST_CONTEXT_QUERY of if the query could not be handled correctly. But the
pad query function should handle differently each case.
This patch changes the gst_vaapi_reply_to_query() for
gst_vaapi_handle_context_query() and changes it usage in all the vaapi plugins
to match the correct context query handling.

Though caps features are supported since GStreamer 1.2, there are some
issues with the features caps negotiation in that version. Nonetheless,
those issues are fixed in GStreamer 1.4. So, the memoy:VASurface caps
feature negotiation is relaxed for GStreamer 1.4.
The guard is the same as in vaapisink's caps template.

Instead of calling gst_vaapi_find_preferred_caps_feature(), which is
expensive, we check the caps from the allocation query, to check the
negotiated feature.
In order to do this verification a new utility function has been implemented:
gst_vaapi_caps_feature_contains().
As this new function shared its logic with gst_caps_has_vaapi_surface(), both
have been refactorized.

Delaying the pool re-negotiation untill we push all decoded (and queued)
frames downstream. Otherwise for the multi-resolution videos, the
GstVideoVideoMemory will be having wrong resolution and which leads
to nasty behaviours, especially when using software renderers.
sample media file: RAP_B_Bossen_1.bin
case explained:
The first SPS Nal will report resoultion of 448x256 and having crop rectangles to
get the final resoultion 416x240.
Starting from 25 th frame, the resolution will change to 416x240. But parser
elements won't report this since the effective croped resolution is same in
both cases. Here the core libgstvaapi will detect this through it's internal
parsing and do all context/pool destory/reset stuffs. Also it will notify this
change to plugins in advance. But if the plugin try to do re-negotiaion of pool
immediately, this will not sync with the resolution of already decoded and queued
frames and which will lead to failure in gst_video_frame_map() in downstream(if we use the
software renderer). So we have to delay the pool renegotiation in vaapidecode,
untill we push all decoded frames downstream.
https://bugzilla.gnome.org/show_bug.cgi?id=753914
Currently we are sharing the input GstVideoCodecState with
GstVaapiDecoder(gst-libs/gst/vaapi) by just doing ref and unref for
each caps change. This is troublesome in many cases, for eg: if
resoultion changes with in a singe stream. Because, when ever there
is a resolution change, GstVideoDecoder will first change the Codec_state->caps
fields with new resolution, but since we are using the same codecstate (ref)
in gstvaapidecode.c, the caps check for input caps change will always fail.

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.

When seeking, the decoder is reset, but the buffer pool is not
re-negotiated, but in reset_full() the code forgets if the negotiated buffer
pool has the GLTextureUpload meta.
The decoder knows that GLTextureUpload meta was negotiated in
decide_allocation(), but this method is not called when seeking.

Fix link when building plugin elements without HEVC support. e.g. don't
try to call into gst_vaapi_decoder_h265_set_alignment() if there is no
support HEVC enabled in libgstvaapi.
Also, drop disabled codecs from static template caps. Add the missing
HEVC static template caps into vaapidecodebin too.
This a cosmetic refactor: gst_vaapidecode_internal_flush() removes its only
label; gst_vaapidecode_finish() is more readable and gst_vaapidecode_purge()
shares the same error message of gst_vaapidecode_internal_flush() when flush
fails.
Add the method gst_vaapidecode_purge(). This method releases the
flushed frames from the decoder.
This new method add more readablity to gst_vaapidecode_destroy()
When a frame is rejected by downstream, the message is logged twice. This
patch removes one of those logging messages.
Also, the reject of a frame doesn't mean an alarming error. This patch demotes
the log message from error to info.
We get one reference when the frame is passed to decode_handle_frame()
and create another one in gst_vaapi_decoder_push_frame().
Usually the frame is handled in gst_vaapidecode_push_decoded_frame().
Here the frame is always released twice:
gst_video_decoder_finish_frame() + gst_video_codec_frame_unref() or
gst_video_decoder_drop_frame() + gst_video_codec_frame_unref().
In gst_vaapidecode_reset_full() both references to the frame must be
released as well.

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

Since GStreamer 1.2 the vmethod reset() in GstVideoDecoderClass was deprecated
and flush() was added.
This patch set the vmethod flush() if the installed GStreamer version is 1.2 or
superior. Otherwise, reset() is set.
v2: 1) In order to avoid symbol collision, the old method gst_vaapidecode_flush()
was renamed to gst_vaapidecode_internal_flush().
2) The new vmethod flush() always do a hard full reset.
v3: 1) Call gst_vaapidecode_internal_flush() first in flush() vmethod, in order to
gather all collected data with gst_video_decoder_have_frame()

In commit 2f8c115 (vaapidecode: use the query virtual methods in 1.4)

this issue.

Sometimes, for example, when switching video streams but keeping
the same sink, the surface will be released after the decoder is
stopped and replaced. This caused a crash because the release
callback was called on an invalid pointer.

GstVideoDecoder, the base class of vaapidecode, added support for
pad queries as virtual methods. This patch enables the use of that
support, while keeping support for lower versions of gstreamer.
This patch is important because GstVideoDecoder takes care of other
queries that might be important in the pipeline managing.
v2: 1) rebase to current master
2) fix indentation with gst-indent
3) simplify the patch layout
4) fix the context query
5) initialise the filter to NULL
6) improve the query log message for gst-1.2
https://bugzilla.gnome.org/show_bug.cgi?id=744406
Because the decoder uses the thread from handle_frame() to decode a frame,
the src pad task creates an unsolveable AB-BA deadlock between
handle_frame() waiting for a free surface and decode_loop() pushing
decoded frames out.
Instead, have handle_frame() take responsibility for pushing surfaces,
and remove the deadlock completely. If you need a separate thread
downstream, you can insert a queue between vaapidecode and its downstream
to get one.
Another justification for the single thread implementation is,
there are two many point of locking in gstreamer-vaapi's current
implementation which can lead to deadlocks.

vaapidecode keeps an output state that use the format
GST_VIDEO_FORMAT_ENCODED, while it crafts a different src caps
for a correct negotiation.
I don't see the rational behind this decoupling, it looks like
unnecessary complexity. This patch simplify this logic keeping
in sync the output state and the src caps.
This patch improves the readability of the function
gst_vaapidecode_update_src_caps() and simplify its logic. Also,
the patch validates if the buffer pool has the configuration for
the GL texture upload meta, in order to set the caps feature
meta:GLTextureUpload. Otherwise, the I420 format is set back.

When vaapidecode finishes the decoding of a frame and pushes it,
if, in the decide_allocation() method, it is determined if the
next element supports the GL texture upload meta feature, the
decoder adds the buffer's meta.
Nonetheless, in the same spirit of the commit 71d3ce4d, the
determination if the next element supports the GL texture upload
meta needs to check both the preferred caps feature *and* if the
allocation query request the API type.
This patch, first removes the unused variable need_pool, and
determines the attribute has_texture_upload_meta using the
preferred caps feature *and* the allocation query.
Also, the feature passed to GstVaapPluginBase is not longer
determined by has_texture_upload_meta, but by the computed
preferred one.
