Since the driver checkup is done at registering, there is no need to do it
when changing the element state from NULL to READY. This patch remove this
vmethod from vaapidecode.
Query the GstVaapiDisplay to know if the driver supports video
postprocessing. If does, then register vaapipostproc and vaapidecodebin

This patch tries to instantiate a GstVaapiDisplay when registering the plugin

There are two main external dependencies that define the feature set of this
plugin: a) the kernel and b) the VA driver
This patch tracks both dependencies, if any of them change, GStreamer will
re-inspect the plugin.
The kernel is tracked through the device files /dev/dri/card*
The VA driver is tracked through the files VA_DRIVERS_PATH/*_drv_video.so,
where VA_DRIVERS_PATH is the one defined in libva package configuration. Also,
the environment variables LIBVA_DRIVERS_PATH and LIBVA_DRIVER_NAME are tracked
since they modify the driver lookup.
Additionally, the environment variable GST_VAAPI_ALL_DRIVERS is tracked too.

This is a fix for a regression of previous commit, which updates the filters
only when the property is set, because it is also required to update the
filter when the color balance interface change its values.
In case that sink caps and src caps are same, and no filtering parameter set,
pass-through mode is enabled.
If new filtering parameter is set during playback, it makes it reconfiguring,
so that pass-through mode is changed
In addition, updating filter is performed during reconfiguration, if needed.

The queue in GstVaapiDecode adds an extra reference to the frames. This patch
unref that extra reference earlier making the code simpler to follow.
https://bugzilla.gnome.org/show_bug.cgi?id=768652
Calling drain() vmethod means "decode any data it can at this point, but that
more data may arrive after". Hence, vaapidecode should check if there is data
in the output adapter and process them, without destroying the decoded picture
buffer (dpb).
Since this operation is done by gst_vaapidecode_internal_flush(), the operation
was refactored into a new function gst_vaapidecode_flush_output_adapter().
https://bugzilla.gnome.org/show_bug.cgi?id=768652
Calling flush() vmethod means "to flush all remaining data from the decoder
without pushing it downstream".
Nonetheless flush() is calling gst_vaapidecode_internal_flush(), which calls
gst_video_decoder_have_frame() if there is still something in the input
adapter, which may push buffers to downstream by calling handle_frame().
This patch changes this behavior by calling gst_vaapidecode_purge() rather
than gst_vaapidecode_internal_flush(), which does what we want: flushes the VA
decoder and releases all the rest of decoded frames.

This patch is a fix for my bad review of commit 6d73ca8d. The element should
be able to return the available raw caps handled by the VA display, but that
only should happen when there a VA display. If there's none, the element
should use the caps template.
https://bugzilla.gnome.org/show_bug.cgi?id=768161
Though USE_{JPEG,VP8,VP9,H265}_ENCODER macros definition depend on USE_ENCODER
macro, it is clearer to nest them, showing explicitly the dependency relation.

There's no need to check for the display in the plugin object when
decide_allocation() vmethod is called, because the display will created or
re-created along the method execution.
Get the pool config just before use it, to avoid a memory leak if the
allocator cannot be instantiated. Similarly, return FALSE if the configuration
cannot be set, avoid keep a not used allocator in the pool.
Instead of instantiating an allocator per vaapivideobufferpool, only one
allocator is instantiated per element's pad and shared among future pools.
If the pad's caps changes, the allocator is reset.
https://bugzilla.gnome.org/show_bug.cgi?id=765435
Originally, vaapivideobufferpool has a set of boolean variables for the
buffer configuration options.
This pach changes these boolean variables for a single bitwise, just as
it is used in pluginbase. Hence, the internal enum was moved to
vaapivideobufferpool header.
https://bugzilla.gnome.org/show_bug.cgi?id=765435
This patch refactors the code in pluginbase in order to centralize the buffer
pool instantiation. As the buffer pool config may have different options, these
are gathered using a bitwise flag.
https://bugzilla.gnome.org/show_bug.cgi?id=765435
Originally vaapivideobufferpool instantiates its own allocator regardless the
received configuration, and it relies in custom configuration options to
choose which kind of allocator instantiate.
This patch transfers the responsibility of the allocator instantiate to
vaapipluginbase and pass it to the vaapivideobufferpool through its
configuration.
* gst/vaapi/gstvaapipluginbase.c
+ set_dmabuf_allocator(): inserts a dmabuf allocator in the bufferpool
+ ensure_sinkpad_buffer_pool(): set a normal vaapi video allocator in
bufferpool configuration
+ gst_vaapi_plugin_base_propose_allocation(): call set_dmabuf_allocator() if
needed.
+ gst_vaapi_plugin_base_decide_allocation(): set a normal vaapi video
allocator in bufferpool configuration
* gst/vaapi/gstvaapivideobufferpool.c
+ gst_vaapi_video_buffer_pool_set_config(): instead of instantiate the
allocator, process the received one through its configuration.

GST_BUFFER_POOL_OPTION_DMABUF_MEMORY since it is not used anymore.
* gst/vaapi/gstvaapivideomemory.c

Since gstreamer-vaapi is coupled with gstreamer releases, there is no need to
keep compatibility definition.
This patch removes the definition of
GST_BUFFER_POOL_OPTION_VIDEO_GL_TEXTURE_UPLOAD_META since it is in
gst-plugins-base version 1.2.2
This is a helper function to improve the readability of
ensure_sinkpad_buffer_pool(). It makes clearer when the buffer pool needs to be
re-instantiated.
This buffer pool may still be processing buffers when a caps renegotiation is
done. This one-liner patch deactivates the pool to drain it before it
de-allocation.
Right now, the decoders create a buffer pool for their sink pad which is not
used at all, because the decoders have never proposed it to upstream.
This patch avoids the buffer pool instantiating when the element inherits from
the GstVideoDecoder class.
This patch is a bit of optimization, since the bufferpool configuration is get
when the pool is created. Hence, we only need to request it when the pool from
the allocation query is reused.
If the offered pool in decide_allocation() vmethod doesn't have the
VAAPI_VIDEO_META option, it is destroyed immediatly and the pointer cleared,
so it could be created later.
When validating the caps from bufferpool config, this patch distinguishes the
error from no caps received (NULL) from the invalid caps (cannot be converted
into GstVideoInfo structure).
Use GST_{ERROR,WARNING}_OBJECT instead of GST_{ERROR,WARNING}, thus the logs
will show the name of the vaapipluginbase instance that failed.
Also, the code-style is fixed, where some error labels need to be surrounded
by braces.
gst_video_info_set_format() and gst_video_info_from_caps() call, internally,
gst_video_info_init(), hence it is not required to call it before them. This
patch removes these spurious calls.
Instead of a dummy alloc() vmethod, the allocator instance set the flag
GST_ALLOCATOR_FLAG_CUSTOM_ALLOC, which is used by the framework to avoid call
gst_allocator_alloc() on the allocator.
This function helper make sense for GStreamer 1.2, but it is not helpful for
greater version since the validation is already done in the API implementation.
Thus, it is removed.
Instead of using gst_video_info_to_caps () to generated the fixed src caps,
this patch enables the first step for caps negotiation with a possible
following caps filter.
_get_preferred_caps() will traverse the possible src caps looking for the one
wit the preferred feature and the preferred color format. Then the color
format, the frame size and the frame rate are fixated.
https://bugzilla.gnome.org/show_bug.cgi?id=758548
Instead of the allowed_srcpad_caps variable, this patch uses the othercaps
from fixate_caps() vmethod to find the preferred caps feature and color
format.
https://bugzilla.gnome.org/show_bug.cgi?id=758548
When running transform_caps() vmethod, returning the srcpad caps, the caps are
early restricted to the element properties set: width, height, format and
force keep aspect.
A new file was added gstvaapipostprocutil.{c,h} where the utilities functions
are stored.
https://bugzilla.gnome.org/show_bug.cgi?id=758548
Instead of #ifdef it should be used #if becasuse USE_GST_GL_HELPERS is always
defined in config.h, but it would be 0 or 1 depending on the configure output.

If the backend driver vendor string is not in a white-list, and the
environment variable GST_VAAPI_ALL_DRIVERS is not set either, the decoder will
change it state from NULL to READY, hence the auto-plug mechanism will look
for another decoder.
This patch assumes the GstContext has already being shared along the pipeline
and the element has a valid GstVaapiDisplay instance.
https://bugzilla.gnome.org/show_bug.cgi?id=764673
In bug 757598 was added the set_context() vmethod chain up in
GstVaapiPluginBase. But it is buggy, since the parent_class address is
assigned to the last element which called gst_vaapi_plugin_base_class_init().
No error has shown up since none of the element's base classes redefined
set_context() vmethod from GstElement, so always the correct function was
called. Still this code is wrong and this patch make it right.
Since set_context() is the same code, a macro is used to implement that code
in all the gst-vaapi elements.
https://bugzilla.gnome.org/show_bug.cgi?id=765368
Since commit 859a2b2, in vaapidecode, allocation query can be different from
the negotiated caps.
When connecting the vaapidecoder to the vaapipostprocessor, the last one will
resize the frame to the negotiated, if and only if, some other parameter is
activated to avoid the passthrough. If it is not, the surface won't be mapped
into a image. If not, the image won't be resized and the output buffer would be
mapped.
This patch will break the passthrough if the allocation query is different
from the negotiation caps, forcing the resizing.
https://bugzilla.gnome.org/show_bug.cgi?id=765095
Instead of using the srcpad template caps for filtering the peer caps, the
function gst_vaapi_find_preferred_caps_feature(), now receives a new parameter
for the element's allowed caps.
With this modification, the vaapipostproc element simplifies a bit its code.
https://bugzilla.gnome.org/show_bug.cgi?id=765223
The native format parameter in gst_vaapi_find_preferred_caps_feature() can be
saved if the out format is used for both: in and out. Thus the code is more
readable.
https://bugzilla.gnome.org/show_bug.cgi?id=765223
If the downstream feature is system memory, the surface has to be mapped,
hence a warning message is logged saying that the driver has to do color
conversions. This might be troublesome because not all the color conversion
combinations are supported by the VA-API drivers, and there is not a reliable
way to know them before hand.
https://bugzilla.gnome.org/show_bug.cgi?id=765223
Instead of setting the requested format by the caller, the function
gst_vaapi_find_preferred_caps_feature() now returns, in the output parameter,
the negotiated format.
A new helper function was added: gst_vaapi_find_preferred_format(), which,
given the format list from the negotiated caps, will choose the best one, if
possible, given the native format.
https://bugzilla.gnome.org/show_bug.cgi?id=765223
This patch simplifies the function gst_vaapi_find_preferred_caps_feature().
Instead of intersecting custom caps to find the preferred feature, the peer
caps are traversed in order to find the preferred feature, according to an
ordered feature priority list.
In the case of GLTextureUploadMeta, the colour format is computed using
GstVideoInfo of the selected fixed caps.

As decoded_info is assured to be valid when gst_vaapidecode_update_src_caps()

When resolving bug 753914, a custom allocation query was added, overlapping
the responsibilities of GstVideoDecoder.
But with the merge of the patches from bug 764421 this overlapping was not

allocation_caps in the GstVideoCodecState when needed.
https://bugzilla.gnome.org/show_bug.cgi?id=764316
The plugins should not expose the feature meta:GstVideoGLTextureUploadMeta in
their caps templates if they were not compiled either with GLX or EGL support.
The compiler might complain of gst_vaapi_create_display_from_handle() being
unused if both EGL and GLX are disabled. This patch avoid that compilation
error.
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.
The P010 video format is the native format used by the vaapi intel driver
for HEVCMain10 decode . Add support for planes and images of this video format.

-- Maintaing decoded surface resoluton and actual display resoultion separately
-- Before pushing every frames downstream, check for the requirement of pool negoation and
output_state negotiation: This is needed to avoid multiple issuses with cropping,
multi-resoluton video handling, more complex multi resolution decode scenarios for vp9decode,
possible wrong behaviour from upstream element to report uncropped values etc. Due to these reasons,
We can't just reliably use the resolution change notification from libgstvaapi for pool renegotiation too.
This is slight overhead, but safe enough. Optimization could be possible though.
https://bugzilla.gnome.org/show_bug.cgi?id=753914
This will help to consoidate the out caps negotiation to a single place,

The former approach to left the bin unfinished has some problems: the context

|<--| vaapidecode |--->| queue |--->|

When the context is shared and the VADisplay has VPP capabilities, before
changing to READY state, the bin is reconfigured dynamically, adding the
vaapipostproc element afeter the queue:
(--------------------------------------------------------)

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.

When processing the GST_CONTEXT_QUERY we should not lose the previous
context in the query, we should only add our display structure.
This patch copies the old context, if it is there, and stamp our display on
it. Otherwise, a new context is created.

This function set the display to an already created context. This function is
going to be used later.
Also, gst_vaapi_video_context_new_with_display() now uses this function.

Since the context messages are sync'ed, the display assignation happens in the
same thread, hence we can know if the display was found or not as soon we call
for it.
In order to take advantage of it, gst_vaapi_video_context_prepare() receives,
as a new parameter, the address of the plugin's display, and reports back if
the display was found and set.

Instead of setting the display to the plugin directly after its creation, do
it through the gstreamer's context mechanism, avoiding double assignations.

The context structure is named "display" which is too generic. The contrary
happens, for example, with GstGL, what uses the same name as the context, and
its logs make more sense.
This patch renames the context structure with the same name as the
context, thus GST_PTR_FORMAT can pretty print it.
https://bugzilla.gnome.org/show_bug.cgi?id=757598
First, refactorized run_context_query() into _gst_context_run_query(), adding
a new parameter: the pad direction, in order to simplify the code.
Second, added a new helper function: _gst_context_query(), which is a generic
context query function. It isolates the operation of running the query and
sets the context if found, also it enhances the logs.
_gst_context_query() is similar to the one used in GstGL. Perhaps, in the
future this helper function will be merged into the core libraries of
GStreamer.
Finally, gst_vaapi_video_context_prepare() was rewritten to use
_gst_context_query().

gst-indent does not handle correctly some expression like function

This patch makes gst-indent to ignore the attributed function
declartion so the followed function definition is not mangled, such

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.

There is a regression from commit 3d8e5e. It was expected the buffer pool

GST_CODEC_PARSER_* variables are defined if builtin codec parsers are disabled
when running configure.
Right now, libgstcodecparsers links only to libgstvaapi, but libgstvaapi_parse
need it if builtin codec parsers are disabled.
This patch adds GST_CODEC_PARSER_* variables to libgstvaapi_parse
compilation. If builtin codec parsers are enable, this variable is null, so it
should work using libgstvaapi, as normal.

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.

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.
