When the source caps change, the filter is destroyed and recreated.
Nonetheless, this happens every time the vaapipostproc starts, since the caps
change detection algorithm does not take in consideration when the caps are
set by first time.

Rather than create a dummy display, if none has propagated as a context, we
should try to get the one from vaapidecode.
As the bin is already in READY state, the vaapidecode should be also in that
state. That means that the contexts have been negotiated, and it should have
already a display.

The former approach to left the bin unfinished has some problems: the context
cannot be shared because the vaapidecode is unlinked in many cases, leading to
creating a VADisplay twice.
Initially the bin is fully functional, constructed as
(-----------------------------------)
| vaapidecodebin |
| (-------------) (-------) |
|<--| 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:
(--------------------------------------------------------)
| vaapidecodebin |
| (-------------) (-------) (---------------) |
|<--| vaapidecode |--->| queue |--->| vaapipostproc |--->|

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

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.

vaapisink takes the display lock, then does a gst_buffer_replace which can
take the lock on the gst_vaapi_video_pool.

the lock on the gst_vaapi_video_pool; if you're unlucky, there are no free
surfaces, which means that gst_vaapi_surface_create is

If vaapisink and vaapipostproc are in different threads, and this happens,

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

where not included in gstreamer-0.10.
Since the support of gstreamer-0.10 is deprecated those classes are not

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

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

The gst_video_colorimetry_to_string() function returns a newly created
string that represents the GstVideoColorimetry value. So, that needs
to be released after usage, in e.g. GST_DEBUG().
Add a "vaapidecodebin" element to vaapi plugins.
Child Elements: "vaapidecode ! queue ! vaapipostproc"
The Reasons for implementing a new bin element:
-- Help to Autoplug Hardware Accelerated Video Postprocessing element in playbin
with out any dependency to upstream gstreamer.
This is to overcome the *unacceptable* delay in upstream gstreamer to get new
features in. Eg: https://bugzilla.gnome.org/show_bug.cgi?id=687182.
Also customers using older gstreamer versions (1.2 and 1.4) will get the
benefit of autoplugging, hardware accelerated deinterlacing support etc.
-- Help to maintain a single thread implementation in vaapidecode.
This will result a dead-lock free vaapidecode in most of the cases.
More details here: https://bugzilla.gnome.org/show_bug.cgi?id=742605https://bugzilla.gnome.org/show_bug.cgi?id=745216
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.

Improve check for upstream element that requires DMABUF buffer pool,
e.g. v4l2src element. In particular, make sure to traverse through
any additional capsfilter for instance.
Note: the traversal to the top-most upstream element could be made
more generic, but we are insofar only interested in supporting pipes
similar to v4l2src or v4l2src ! capsfilter, e.g. with an explicit
specification for a desired video camera format, or resolution.
The dmabuf allocator would close the DMABUF handle passed in the init
function gst_dmabuf_allocator_alloc(). So, we need to dup() it so that
to avoid a double close, ultimately in the underlying driver that owns
the DMABUF handle.
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.

Currently the src caps are set immediately after the sink caps are set, but in
that moment the pipeline might not fully constructed and the video sink has
not negotiated its supported caps and features. As a consequence, in many cases
of playback, the least optimized caps feature is forced. This is partially the
responsible of bug #744039.
Also, vaapidecode doesn't attend the reconfigure events from downstream,
which is a problem too, since the video sink can be changed with different
caps features.
This patch delays the src caps, setting them until the first frame arrives to
the decoder, assuming until that very moment the whole pipeline is already
negotiated. Particularly, it checks if the src pad needs to be reconfigured,
as a consequence of a reconfiguration event from downstream.
A key part of this patch is the new GstVaapiCapsFeature
GST_VAAPI_CAPS_FEATURE_NOT_NEGOTIATED, which is returned when the src pad
doesn't have a peer yet. Also, for a better report of the caps allowed
through the src pad and its peer, this patch uses gst_pad_get_allowed_caps()
instead of gst_pad_peer_query_caps() when looking for the preferred feature.
v3: move the input_state unref to close(), since videodecoder resets at
some events such as navigation.
v4: a) the state_changed() callback replaces the input_state if the media
changed, so this case is also handled.
b) since the parameter ref_state in gst_vaapidecode_update_src_caps() is
always the input_state, the parameter were removed.
c) there were a lot of repeated code handling the input_state, so I
refactored it with the function gst_vaapi_decode_input_state_replace().

Working on bug #743687, I realized that vaapidecode always adds to its buffer
pool the config option GST_BUFFER_POOL_OPTION_VIDEO_GL_TEXTURE_UPLOAD_META if
the decide_allocation()'s query has GST_VIDEO_GL_TEXTURE_UPLOAD_META_API_TYPE.
Nevertheless, there are occasions where the query has the API type, but the
last negotiated caps don't have the feature meta:GstVideoGLTextureUploadMeta.
Under this contradiction, vaapidecode adds the GLTextureUploadMeta API to its
buffer pool configuration, and adds its buffer's meta to each output buffer,
even if the negotiated caps feature is memory:SystemMemory with I420 color
format.
This kind of output buffers chokes ClutterAutoVideosSink, since it uses a map
that relates caps <-> GL upload method. If it receives a buffer with color
format I420, it assumes that it doesn't have a texture upload meta, because
only those with RGB color format has it. Our buffers, with I420 format, say
that they have the upload meta too. In that case the mapped method is a dummy
one which does nothing. I reported this issue in bug #744039 (the patch,
obviously, was rejected).
This patch workarounds the problem: the buffer pool's configuration option
GST_BUFFER_POOL_OPTION_VIDEO_GL_TEXTURE_UPLOAD_META is set if and only if the
query has the GST_VIDEO_GL_TEXTURE_UPLOAD_META_API_TYPE *and* the negotiated
caps feature is meta:GstVideoGLTextureUploadMeta.
I have tested these patches with gst-master (1.5), gst-1.4 and gst-1.2 and
in all they seem to work correctly.

Add support for GstVideoGLTextureOrientation modes. In particular,
add orientation flags to the GstVaapiTexture wrapper and the GLX
implementations. Default mode is that texture memory is laid out
with top lines first, left row first. Flags indicate whether the
X or Y axis need to be inverted.
Some frameworks (EFL) expect BGRA textures for storage. However,
adding support for that broadly into GStreamer framework implies
two kinds of hacks: (i) libgstgl helpers currently do not support
BGRA textures correctly, (ii) we need to better parse downstream
suggested caps and intersect them with what the VA plugin elements
can offer to them for GL texturing.
When multiple display servers are available, the glimagesink element
(from GStreamer 1.4) may not be able to derive a global display in
Wayland. Rather, a "window"-specific display is created. In this case,
the GstGLDisplay handle available through GstGLContext is invalid.
So, try to improve heuristics for display server characterisation in
those particular situations.
Add initial support for EGL through GstVideoGLTextureUploadMeta.
Fix gst_vaapi_ensure_display() to allocate a GstVaapiDisplay off the
downstream supplied GstGLContext configuration, i.e. use its native
display handle to create a GstVaapiDisplay of type X11 or Wayland ;
and use the desired OpenGL API to allocate the GstVaapiDisplayEGL
wrapper.

Sync video texture sizes to GstVideoGLTextureUploadMeta private date,
i.e. GstVaapiVideoMetaTexture, on a regular basis. In particular, we
now update the texture size from the GstVideoMeta, if any, or reset
to some defaults otherwise.
If a GstGLContext is supplied by the downstream element, then make
sure that the VA plugin element gets a compatible display to what
is requested by the GL context. e.g. re-allocate a VA/GLX display
when a GLX context is provided by the downstream element.
Record GL context supplied by downstream elements. This can be useful,
and further needed, to enforce run-time check that the GL context is
compatible for use by libgstvaapi. e.g. check that we don't create a
VA/GLX display for EGL/X11 contexts.

Reset the VA decoder after updating the base plugin caps, and most
importantly, after GstVideoDecoder negotiation. The reason behind
this is that the negotiation could trigger a last decide_allocation()
where we could actually derive a new GstVaapiDisplay to use from the
downstream element. e.g. GLX backend.
Query caps filtering should be always done on top of allowed caps instead
of existing fixed caps on a particular pad.
This fixes the mvc stream decoding when there is a base view(high profile)
and non-base view(stereo-high profile).
According to documentation[1] when receiving a GST_QUERY_CAPS
the return value should be all formats that this elements supports,
taking into account limitations of peer elements further downstream
or upstream, sorted by order of preference, highest preference first.
This patch add those limitations intersecting with the received
filter in the query. Also takes into account the already negotiated
caps. Also adds the processing of the query on the SRC pad.
