Rather than create a dummy display, if none has propagated as a context, we

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 |
| (-------------) (-------) (---------------) |

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

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
called. gst_vaapi_surface_create takes the display lock.
If vaapisink and vaapipostproc are in different threads, and this happens,

gst_vaapi_video_pool lock. vaapipostproc holds the gst_vaapi_video_pool lock

The problem with this is that creating the filter causes the display to
be selected, and the caps query happens while linking the element. So,
if the downstream or upstream element is using a specific display
object, it won't be propagated correctly to the postproc as it already
has a display at this point.

vaapisink inherits from GstVideoSink, in order to use its functionality (such
as ::show-preroll-frame property), we should use its vmethod show_frame(),
rather than call ourselves render() and preroll().
This patch adds the signal ::handoff and the property signal-handoffs. If the
property is set TRUE, the signal ::handoff is emitted just after the buffer is
rendered.

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 gst_video_colorimetry_to_string() function returns a newly created

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

in sync the output state and the src caps.
This patch improves the readability of the function

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

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 ;

wrapper.

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

Otherwise restarting may fail because the state of vaapipluginbase and

Split GstVideoDecoder::set_format() handler to first update the sink
pad caps and reset the active VA decoder instance based on those, and
then update the src pad caps whenever possible, e.g. when the caps
specify a valid video resolution.
In some occasions, a buffer pool is created for pre-initialization
purposes regardless of whether a valid image size is available or
not. However, during actual decode stage, the vaapidecode element
is expected to update the srcpad caps with the new dimensions, thus
also triggering a reset of the underlying bufferpool.
If the best downstream capsfeature turns out to be GLMemory, then make
sure to propagate RGBA video format in caps to that element. This fixes
the following pipeline: ... ! vaapipostproc ! glimagesink.
When an explicit output video format is selected, from an src pad
capsfilter, make sure that the downstream element actually supports
that format. In particular, fix crash with the following pipelines:
... ! vaapipostproc ! video/x-raw,format=XXX ! xvimagesink ; where
XXX is a format not supported by xvimagesink.
While doing so, also reduce the set of src pad filter caps to the
actual set of allowed src pad caps.
The ensure_surface() and ensure_image() functions shall only relate
to the underlying backing store. The actual current flags are to be
updated only through ensure_{surface,image}_is_current() or very other
particular cases in GstMemory hooks.
If the surface proxy is updated into the GstVaapiVideoMemory, then
it is assumed it is the most current representation of the current
video frame. Likewise, make a few more arrangements to have the
"current " flags set more consistently.
When interacting with SW elements, the buffers and underlying video
memory could be mapped as read/write. However, we need to use those
buffers again as plain VA surfaces, we have to make sure the VA image
is thus committed back to VA surface memory.
This fixes pipelines involving avdec_* and vaapi{postproc,sink}.
Hence vaapisink can display buffers decoded by gst-libav, or HW decoded
buffers can be further processed in-place, e.g. with a textoverlay.

If no explicit output surface format is supplied try to keep the one
supplied through the sink pad caps. This avoids a useless copy, even
if things are kept in GPU memory.
This is a performance regression from git commit dfa70b9.
If only advanced deinterlacing is requested, i.e. deinterlacing is
the only active algorithm to apply with source and output surface
formats being the same, then make sure to enable VPP processing.
Otherwise, allow fallback to bob-deinterlacing with simple rendering
flags alteration.
Add a default decide_allocation() hook to GstVaapiPluginBase. The caps
feature argument can be used to force a bufferpool with a specific kind
of memory.
Add GST_VAAPI_VIDEO_BUFFER_POOL_ACQUIRE_FLAG_NO_ALLOC params flag that
can be used to disable early allocations of vaapi video metas on buffers,
thus delagating that to the bufferpool user.
Default to I420 format for output surfaces so that to match the usual
GStreamer pipelines. Though, internally, we could still opt for NV12
surface formats, i.e. default format=ENCODED is a hint for that, thus
delegating the decision to the VA driver.
Use the new gst_caps_has_vaapi_surface() helper function to detect
whether the sink pad caps contain native VA surfaces, or not, i.e.
no raw video caps.
Also rename is_raw_yuv to get_va_surfaces to make the variable more
explicit as we just want a way to differentiate raw video caps from
VA surfaces actually.
The "discontinuity" tracking code, whereby lost frames are tentatively
detected, is inoperant if the sink pad buffer timestamps are not right
to begin with.
This is a temporary workaround until the following bug is fixed:
https://bugzilla.gnome.org/show_bug.cgi?id=734386
In order to make the discontinuity detection code useful, we need to
detect the lost frames in the history as early as the previous frame.
This is because some VA implementations only support one reference
frame for advanced deinterlacing.
In practice, turn the condition for detecting new frame that is beyond
the previous frame from field_duration*2 to field_duration*3, i.e.
nothing received for the past frame and a half because of possible
rounding errors when calculating the field-duration either in this
element (vaapipostproc), or from the upstream element (parser element).
This is a regression introduced with commit faefd62.
https://bugzilla.gnome.org/show_bug.cgi?id=734135
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.
Simplify the creation and installation process of properties, by first
accumulating them into a g_properties[] array, and next calling into
g_object_class_install_properties().
Also add missing docs and flags to some properties.
Move code around in a more logical way. Introduce GST_VAAPISINK_CAST()
helper macro and use it wherever we know the object is a GstBaseSink or
any base class. Drop explicit initializers for values that have defaults
set to zero.
Introduce new backends vtable so that to have clean separation between
display dependent code and common base code. That's a "soft" separation,
we don't really need dedicated objects.

Support for X11 "synchronous" mode was never implemented, and was only

Rendering with GLX in vaapisink is kind of useless nowadays, including
OpenGL related fancy effects. Plain VA/GLX interfaces are also getting
deprecated in favor of EGL, or more direct buffer sharing with actual
GL textures.
Should testing of interop with GLX be needed, one could still be using
the modern cluttersink or glimagesink elements.
https://bugzilla.gnome.org/show_bug.cgi?id=733984
Allow dynamic changes to the window, e.g. performed by the user, and
make sure to refresh its contents, while preserving aspect ratio.
In practice, Expose and ConfigureNotify events are tracked in X11
display mode by default. This occurs in a separte event thread, and
this is similar to what xvimagesink does. Any of those events will
trigger a reconfiguration of the window "soft" size, subsequently
the render-rect when necessary, and finally _expose() the result.
The default of handle_events=true can be changed programatically via
gst_x_overlay_handle_events().

The gst_vaapidecode_decode_loop() function is called within a separate
task to fetch and output all frames that were decoded so far. So, if
the decoder_loop_status is forcibly set to EOS when _finish() is called,
then we are bound to exist the task without submitting the pending
frames.
If the downstream element error'ed out, then the gst_pad_push() would
propagate up an error and so we will get it right for cutting off
_finish() early in that case.
This is a regression from 6003596.
https://bugzilla.gnome.org/show_bug.cgi?id=733897
Fixes a hang/race on shutdown where _decode_loop() had already completed
its execution and _finish() was waiting on a GCond for decode_loop()

but _decode_loop() endlessly returns before signalling completion
iff the decoder instance returns GST_FLOW_OK.

Now that we always track the currently active video buffer, it is
not necessary to automatically increase its reference since this is
implicitly performed in ::show_frame() through the get_input_buffer()
helper from GstVaapiPluginBase class.
This is a regression from a26df80.
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.
Make sure to propagate memory:VASurface capsfeature to srcpad caps
only for GStreamer >= 1.5 as the plug-in elements in GStreamer 1.4
core currently miss additional patches available in 1.5-git (1.6).
This is a temporary workaround.
If a multiview stream is decoded, multiple view components are submitted
as is downstream. It is the responsibility of the sink element to display
the required view components. By default, always select the frame buffer
that matches the view-id of the very first frame to be displayed.
However, introduce a "view-id" property to allow the selection of a
specific view component of interest to display.
Always record the VA surface that is currently being rendered, no matter
the fact we are using texturedblit or overlay. That's because in some
occasions, we need to refresh or resize the displayed contents based on
new events. e.g. user-resized window.
Besides, it's simpler to track the last video buffer in GstVaapiSink than
through the base sink "last-sample".
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.
https://bugzilla.gnome.org/show_bug.cgi?id=722247
Always add VideoAlignment bufferpool option if the downstream element
expects its own pool to be used but does not offer it through a proper
propose_allocation() implementation for instance, and that the ALLOCATION
query does not expose the availability of the Video Meta API.
This fixes propagation of video buffer stride information to Firefox.
Make sure to always prefer native internal formats for the VA surfaces
that get allocated. Also disable "direct-rendering" mode in this case.
This is needed so that to make sure that anything that gets out of the
decoder, or anything that gets into the encoder, is in native format
for the hardware, and thus the driver doesn't need to perform implicit
conversions in there. Interop with SW elements is still available with
fast implementations of VA imaging APIs.
Forbid shares of GstMemory instances, and rather make copy of it. This
effectively copies the GstMemory structure and enclosed metadata, but
this does not copy the VA surface contents itself. It should though.
This fixes preroll and makes sure to not download garbage for the first
frame when a SW rendering sink is used.
Use an image pool to hold VA images to be used for downloads/uploads
of contents for the associated surface.
This is an optmization for size. So, instead of creating as many VA
images as there are buffers (then VA surfaces) allocated, we only
maintain a minimal set of live VA images, thus preserving memory
resources.
Disable read-write mappings if "direct-rendering" is not supported.
Since the ordering of read and write operations is not specified,
this would require to always download the VA surface on _map(), then
commit the temporary VA image back to the VA surface on _unmap().
Some SW decoding plug-in elements still use R/W mappings though.
https://bugzilla.gnome.org/show_bug.cgi?id=733242
Fix error messages introduced in the previous commit for the _map()
imaplementation. Also use the new get_image_data() helper function
to determine the base pixels data buffer from a GstVaapiImage when
updating the video info structure from it.
Allow raw pixels of the whole frame to be mapped read-only. i.e. in
cases where the buffer pool is allocated without VideoMeta API, thus
individual planes cannot be mapped.
This is initial support for Firefox >= 30.
https://bugzilla.gnome.org/show_bug.cgi?id=731886
While creating the vaapi video allocator, make sure the associated
surface pool has correct format instead of defaulting to NV12 video
format even though there is no direct rendering support.
https://bugzilla.gnome.org/show_bug.cgi?id=732691
Make sure to always update the VA surface pointer whenever the proxy
changes. This used to only work when the VA surface is written to, in
interop with SW element ("upload" feature), and this now fixes cases
when the VA surface is needed for reading, in interop with SW element
("download" feature).
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.
Fix support for VA surface download capability in vaapidecode element
for GStreamer >= 1.2. This is a fix to supporting libva-vdpau-driver,
but also the libva-intel-driver while performing hardware accelerated
conversions from the native VA surface format (NV12) to the desired
output VA image format.
For instance, this fixes pipelines involving vaapidecode ! xvimagesink.
https://bugzilla.gnome.org/show_bug.cgi?id=733243
When playbin/decodebin builds the pipeline, it puts decoders and sinks
into different bins and forwards the queries from bins to bins. So in
the initials steps the pipeline is built iteratively by playbin and
looks like this :
[filesrc]
[filesrc] -> [typefind]
[filesrc] -> [typefind] -> [demuxer]
[filesrc] -> [typefind] -> [demuxer] -> [decoder]
At this point the decoder is asked for its SRC caps and it will make a
choice based on what gst_pad_peer_query_caps() returns. The problem is
that the caps returns at that point includes caps features like ANY,
essentially because playbin can plug in additional elements like
videoscale, videoconv or deinterlace.
This patch adds a another call to
gst_vaapi_find_preferred_caps_feature() when the decoder decides its
allocation, to make sure we asks the downstream elements when the
entire pipeline has been built.

Force early initializatin of the GstVaapiDisplay so that to make sure
that the sink element display object is presented first to upstream
elements, as it will be correctly featuring the requested display type
by the user.
Otherwise, we might end up in situations where a VA/X11 display is
initialized in vaapidecode, then we try VA/DRM display in vaapisink
(as requested by the "display" property), but this would cause a failure
because we cannot acquire a DRM display that was previously acquired
through another backend (e.g. VA/X11).
When a new display is settled through GstElement::set_context() (>= 1.2),
or GstVideoContext::set_context() (<= 1.0), then we shall also update the
associated display type.

Add interface to communicate the encoder resolution and related info

Note that gst_vaapi_encoder_set_codec_state() is also a synchronization
point for codec config. This means that the encoder is reconfigured
there to match the latest properties.
Don't try to destroy an encoder, in GstVideoEncoder::finish() handler,
if it was not created in the first place. Return "not-negotiated" error
since this means we did not even reach GstVideoEncoder::set_format(),

The specified caps in gst_video_encoder_set_output_state() function

could be delayed until before gst_video_encoder_finish_frame() is

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