In order to handle correctly seek and other operations, vaapiencode should
flush all the remaining data from the encoder without pushing it downstream.
This patch implements the flush() vmethod, only after of pausing the
source pad task, and restarting it again after the flush stop.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=768652
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.
Under certain conditions the element might receive a positive context query
but without a context instance. This situation will lead to a segmentation
fault when traversing the context list in the pipeline.

If vaapisink received a caps query before getting a VA display, it returned
only the surfaces related caps. This behavior broke the autovideosink

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/vaapi/gstvaapivideobufferpool.h: removed
GST_BUFFER_POOL_OPTION_DMABUF_MEMORY since it is not used anymore.
* gst/vaapi/gstvaapivideomemory.c
+ gst_vaapi_is_dmabuf_allocator(): new helper function to identify a dmabuf
allocator with the vaapi qdata.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=765702
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.
https://bugzilla.gnome.org/show_bug.cgi?id=765223
As decoded_info is assured to be valid when gst_vaapidecode_update_src_caps()
is called, then we don't need to verify or replace it with the sinkpad info
(reference state).

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
required anymore. This patch restores this situation setting the
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.
https://bugzilla.gnome.org/show_bug.cgi?id=759181
Instead of using a single value for the texture type, use an array with 4

After the decoding of first frame, try to extract the exact
decoded surface format using vaDeriveImage and keep this
as the format in decoded_info.
https://bugzilla.gnome.org/show_bug.cgi?id=753914
-- 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,
which will make the code simpler, allows to get the exact decoded format
if needed and the selected chroma type too.
