75e7a0a36c vaapidecode: return pad's template caps if no display
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.

d69f747d09 plugins: don't create display at caps query
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.

b2707c8eec plugins: fix context query handling
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.

b76f4825c5 vaapidecode: relax guards for memory:VASurface capsfeature
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.

6d9f31e305 vaapidecode: use caps to check the features
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.

6eba201f32 vaapidecode: Rework the re-negotiation code to handle multi resoultion videos
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.

ba8fcf5435 vaapidecode: Always keep a copy of input codec state

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.

aafa59f01e vaapidecode: Switch back to Single thread implementation
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.

e4f8d14979 vaapidecode: upload meta only if feature and allocation
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.

9799875df4 vaapidecode: delayed src caps negotiation
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().

8c93c842ef plugins: add support for BGRA textures.
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.

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

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.

334a0ca8bd vaapidecode: make decoder work with playbin
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.

means NV12, I420 or YV12 but also ENCODED if we cannot determine the
underlying VA surface format, or if it is actually not allowed to get
access to the surface contents.

b4eb1dcd42 plugins: expose the expected format for GstVideoGLTextureUploadMeta.
Fix vaapidecode srcpad caps to only expose RGBA video format for the
meta:GstVideoGLTextureUploadMeta feature. That's only what is supported
so far. Besides, drop this meta from the vaapisink sinkpad caps since
we really don't support that for rendering.

a00ae0918a plugins: cope with new GstVaapiVideoMeta API.
Update plugin elements with the new GstVaapiVideoMeta API.

This also fixes support for subpictures/overlay because GstVideoDecoder
generates a sub-buffer from the GstVaapiVideoBuffer. So, that sub-buffer
is marked as read-only. However, when comes in the textoverlay element
for example, it checks whether the input buffer is writable. Since that
buffer read-only, then a new GstBuffer is created. Since gst_buffer_copy()
does not preserve the parent field, the generated buffer in textoverlay
is not exploitable because we lost all VA specific information.

Now, with GstVaapiVideoMeta information attached to a standard GstBuffer,
all information are preserved through gst_buffer_copy() since the latter
does copy metadata (qdata in this case).
