So far vaapi encoder does not set profile to src caps. This patch makes it
setting profile to src caps, which is determined by itself.
In addition, if encoder chose different profile, which is not negotiated with
downstream, we should set compatible profile to make negotiation working.
https://bugzilla.gnome.org/show_bug.cgi?id=757941
Check if the requested profile in source caps, is supported by the
VA driver. If it is not, an info log message is send saying that
another (compatible?) profile will be used.
https://bugzilla.gnome.org/show_bug.cgi?id=757941
First check if downstream requests ANY caps. If so, byte-stream is
used and the profile will be choose by the encoder. If dowstream
requests EMPTY caps, the negotiation will fail.
Lately, byte-stream and profile are looked in the allowed caps.
https://bugzilla.gnome.org/show_bug.cgi?id=757941
The check for avc stream format was done in the vaapi encoder's
vmethod get_caps(), but that is wrong since it has to be check
when encoder set_format().
https://bugzilla.gnome.org/show_bug.cgi?id=757941
vaapipostproc didn't negotiate the proper multiview caps losing
downstream information.
This patch enables the playing of MVC encoded stream by setting
the proper multiview mode/flags and views to src caps, according

There is another regression with 7a206923 when setting the video
info for the video meta, it should be the one from the image's
allocator rather from the allocation caps.
Test pipeline:
gst-launch-1.0 filesrc location=bug766184.flv ! decodebin \
! tee ! videoconvert ! videoscale \
! video/x-raw, width=1920, height=1080 ! xvimagesink
There is a regression in 7a206923, since the buffer pool ditches all
the buffers generated by them because the pool config size is
different of the buffer's size.
Test pipeline:
gst-launch-1.0 filesrc location=big_buck_bunny_1080p_h264.mov \
! qtdemux ! vaapih264dec ! vaapipostproc ! xvimagesink \
--gst-debug=GST_PERFORMANCE:5
The allocator may update the buffer size according to the VA surface
properties. In order to do this, the video info is modified when the
allocator is created, which reports through the allocation info the
updated size, and set it to the pool config.
Refactor the set_config() virtual method considering a cleaner
approach to allocator instanciation, if it it not set or if it is
not valid for the pool.
https://bugzilla.gnome.org/show_bug.cgi?id=783599
The vaapi video decoders might have different allocation caps from
the negotiation caps, thus the GstVideoMeta shall use the negotiation
caps, not the allocation caps.
This was done before reusing gst_allocator_get_vaapi_video_info(),
storing there the negotiation caps if they differ from the allocation
ones, but this strategy felt short when the allocator had to be reset
in the vaapi buffer pool, since we need both.
This patch adds gst_allocator_set_vaapi_negotiated_video_info() and
gst_allocator_get_vaapi_negotiated_video_info() to store the
negotiated video info in the allocator, and distinguish it from
the allocation video info.
https://bugzilla.gnome.org/show_bug.cgi?id=783599
Renamed local video info structure names in set_config() vitual
method. The purpose of their renaming is to clarify the origin
of those structures, whether come from passed caps parameter

https://bugzilla.gnome.org/show_bug.cgi?id=783599
Renamed private GstVideoInfo structure video_info to allocation_vinfo
and alloc_info to negotiated_vinfo.
The purpose of these renaming is to clarify the origin and purpose of
these private variables:
video_info (now allocation_vinfo) comes from the bufferpool
configuration. It describes the physical video resolution to be
allocated by the allocator, which may be different from the
negotiated one.
alloc_info (now vmeta_vinfo) comes from the negotiated caps in
the pipeline. It represents how the frame is going to be mapped
using the video meta.
In Intel's VA-API backend, the allocation_vinfo resolution is
bigger than the negotiated_info.

Sometimes a video decoder could set different buffer pool

Overriding the vmethod acquire_buffer() it is possible to attach the
right GstMemory to the current acquired buffer.
As a matter of fact, this acquired buffer may contain any instantiated
GstFdmemory, since this buffer have been popped out from the buffer
pool, which is a FIFO queue. So there is no garantee that this buffer
matches with the current processed surface. Evenmore, the VA driver
might not use a FIFO queue. Therefore, it is no way to guess on the
ordering.
In short, acquire_buffer on the VA driver and on the buffer pool return
none matching data, we have to manually attach the right GstFdMemory to
the acquired GstBuffer. The right GstMemory is the one associated with
the current surface.

If the negotiated caps are raw caps and downstream supports the
EGL_EXT_image_dma_buf_import extension, then the created allocator
is the DMAbuf, configured to downstream.
At this moment, the only element which can push dmabuf-based buffers
to downstream, is vaapipostproc.
In order to enable, in the future, dmabuf-based buffers, the vaapi base
plugin needs to check if downstream can import dmabuf buffers.
This patch checks if downstream can handle dmabuf, by introspecting the
shared GL context. If the GL context is EGL/GLES2 and have the extension
EGL_EXT_image_dma_buf_import, then dmabuf can be negotiated.

Every time a new buffer is allocated, the pool is activated. This
doesn't impact in performance since gst_buffer_pool_set_active()
checks the current state of the pool. Nonetheless it logs out a

if it is enabled.
To avoid this log flooding first the pool state is checked before
changing it.
When a new sink caps arrive the internal decoder state is updated
and, if it is, request a downstream renegotiation.
Previously, when new caps arrived the whole decoder where destroyed
and recreated. Now, if the caps are compatible or has the same codec,
the internal decoder is kept, but a downstream renegotiation is
requested.

Rename the parameters 'vip' and 'flags' to 'alloc_info' and
'surface_alloc_flags' respectively. The purpose of this change is
to auto-document those parameters.
Also, aligned to this patch, the local 'alloc_info' variable was
renamed as 'surface_info', because it stores the possible surface's
video info, not the allocate one.
In order to auto-document the code, this patch renames the 'vip'
parameter in the functions related to gst_vaapi_video_allocator_new ()
to 'alloc_info', since it declares the allocation video info from

gst_vaapi_surface_new_with_format() is a wrapper for

When an instance of GstVaapiVideoAllocator fails at initializing, the

This reverts commit 3285121181.
videodecode's negotiate() vmethod is also called when events arrive,

When the allocator is created, it stores the allocation caps. But sometimes
the "allocation caps" may be different from the "negotiation caps".
In this case, the allocator should store the negotiation caps since they
are the ones used for frame mapping with GstVideoMeta.
When vaapispostproc is used, this is not a problem since the element is assume
to resize. But when using a vaapi decoder only, with a software renderer, it
fails in this case.
https://bugzilla.gnome.org/show_bug.cgi?id=773323
Just as vaapipostproc, VA decoder's context can be queried to get the possible
raw formats, so, the src caps can negotiate the exact caps that the context
supports.
Since when the sink pad allocator is created, it is decided if the required
one is vaapi allocator or dmabuf allocator, there is no need to force its set
again.
When running gst-discoverer-1.0, in certain media, vaapipostroc is stopped
meanwhile it is transforming caps. The problem is that stop() calls
gst_vaapi_plugin_base_close(), which nullifies the element's va display, but
the va display is used in tranform_caps() when it is extracting the possible
format conversions. This display disappearing generates warning messages.
This patch holds a local reference of va display at ensure_allowed_raw_caps()
hence it doesn't go away meanwhile it is used, even if the
gst_vaapi_plugin_base_close() is called in other thread.

Enable the direct rendering with linear surfaces if the negotiated src caps

Instead of receiving the GstVideoInfo structure as parameter, get the original
GstCaps from ensure_sinkpad_buffer_pool(), in this way we could decide better
which allocator instantiate.
If the allocator was configured to use direct upload or rendering, the
generated derived image created at mapping needs to be destroyed after
unmapping, because, in order to process the surface, it should not be marked
as "busy" by the driver.
The way to experiment with the direct rendering is through and internal
compiler pre-processor flag.
The current change set enables a way to specified at run-time, as a flag
passed to the allocator at instanciation time.
This patch is to change the inheritance of GstVaapiDisplay to GstObject,
instead of GstVaapiMiniObject. In this way we can use all the available
infrastructure for GObject/GstObject such as GstTracer, GIR, etc.
In addition, a new debug category for GstVaapiDisplay is created to make it
easier to trace debug messages. It is named "vaapidisplay" and it transverse
all the VA display backends (DRM, GLX, EGL, Wayland, ...)
This patch is a step forward to expose GstVaapiDisplay for users in a future

by matching the GL texture id for each frame upload process, avoiding the
internal texture structure creation and its following destruction.

set_format() is called by upstream when the stream capabilites has changed.
Before, if the new stream is compatible with the old one the VA decoder was
not destroyed. Nonetheless, with this behavoir, the VA decoder ignores
when the upstreamer parsers gets more details of the stream, such as the
framerate. Hence, when the src caps are negotiates, the further sink caps
updates are ignored.
This patch forces the VA decoder destroying and recreation when set_format()
is called.

Encoders claim to support a whole bunch of input formats but then
just error out if the format is not actually supported, even if
there's a converter in front. This means they're not fit for
autoplugging in encodebin or camerabin yet and therefore should
not have a rank. People can still use them in custom pipelines.

Check earlier if upstream video source has activated the dmabuf-import
io-mode (hack to disappear soon), thus we can avoid the re-assignation of a
new allocator.
Add the method gst_allocator_get_vaapi_image_size() for the
GstVaapiVideoAllocator, which gets the size of the allocated images with the
current video info.
This method replaces the direct call to the allocator's image info when the
pool is configured.
Depends on media, video size is sometimes updated with new allocator.
It leads to dismatch between bufferpool's set size and real allocated buffer size.
In this case, it causes every buffer is freed during release in bufferpool,
which should be reused. This affects performance.

Delay the GstVaapiDisplay instantiating until when changing the state from
READY to PAUSE. In this way the element has more chances to find an already
created GstVaapiDisplay, or a GL context, in the pipeline.
https://bugzilla.gnome.org/show_bug.cgi?id=766206
The function gst_vaapi_create_display_from_gl_context() cretes a
GstVaapiDisplay given a GstGLContext. But it didn't created a GLX VA display
when the GL platform was GLX, but a plain X11 VA display.
This patch fixes that, by querying the GL platform earlier.

Using the GstContext mechanism, it is possible to find if the pipeline

Since the driver checkup is done at registering, there is no need to do it

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

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.
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

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.

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

Originally vaapivideobufferpool instantiates its own allocator regardless the
received configuration, and it relies in custom configuration options to
choose which kind of allocator instantiate.

configuration.
* gst/vaapi/gstvaapipluginbase.c

+ ensure_sinkpad_buffer_pool(): set a normal vaapi video allocator in

+ 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

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.
