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.

gst_vaapi_dmabuf_memory_new() always exports a surface. Previously, it
had to create that surface. Now it can also export an already provided
surface. It is useful to export decoder's surfaces (from VA context).

Do not add the meta:GstVideoGLTextureUploadMeta feature if the render
element can handle dmabuf-based buffers, avoiding its negotiation.

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.

The surface created for downstream is going to be filled by VAAPI
elements. So, the driver needs write access on that surface.
This patch releases the derived image held by the proxy, thus the
surface is unmarked as busy.
This is how it has to be done as discussed on libva mailing list.

If a GstVaapiDisplay is not found in the GStreamer context sharing,
then VAAPI elements look for a local GstGLContext in gst context
sharing mechanism ('gst.gl.local.context').
If this GstGLContext not found either then, only the VAAPI decoders
and the VAAPI post-processor, will try to instantiate a new
GstGLContext.
If a valid GstGLContext is received, then a new GstVaapiDisplay will
be instantiated with the platform, API and windowing specified by the
instantiated GstGLContext.

Instead of calling g_return_val_if_fail() to check the context type, we
should use a normal conditional, since it is possible that other context types
can arrive and try to be assigned. Otherwise a critical log message is
printed.
This happens when we use playbin3 with vaapipostproc as video-filter.

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
message if the state is the same, and it floods the logging subsystem
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
the vaapi buffer pool.
gst_vaapi_surface_new_with_format() is a wrapper for
gst_vaapi_surface_new_full (). In this case, the former is simpler
than the first. This patch changes that.
If src pad caps have changed, it needs to notify it downstream. In
addition, do not set passthrough if they have changed.
Otherwise, transform sometimes starts processing before caps change.
The passthrough value will be set in fixate later in this case.

When an instance of GstVaapiVideoAllocator fails at initializing, the
log message should not include the allocator's object, because it is
going to be unrefed.
This reverts commit 3285121181.
videodecode's negotiate() vmethod is also called when events arrive,
but this would mean that the proper configuration of sink pad might
not be complete, thus we should not update the src pad.
Let's keep the old non-vmethod negotitate().
Added the inlined function allocator_configure_pools() moving out code
from gst_vaapi_video_allocator_new() to make clear that it is a
post-initalization of the object.
Since video_info stores the GstVideoInfo of the allocation caps,
it is clear if we rename it as allocation_info, to distinguish it
later from negotiation_info.

In commit ca0c3fd6 we remove the dynamic configuration if the bin

Nonetheless we were wrong, because it is possible to request, with a

Since we want to add a way to disable the post-processor through
environment variables, this remove feature is required again.
If the environment variable GST_VAAPI_DISABLE_VPP is defined the

Instead of creating the VA display before setting the bus to the

Basically, this commit is a revert of

That was done when the GStreamer's context sharing was not mature
enough as now. There is no reason to keep this hack.

there is no need to add a video crop meta with the negotiation caps.

First, deactivate source pad pool when the out caps change, and if so,
destroy texture map, the source pad allocator and pool only if the
new caps are different from the ones already set.
This is related with bug 758907 when no vaapipostproc is used (no
vaapidecodebin). In order to negotiate downstream we need to destroy
the source pad allocator, otherwise the same allocated buffers are
used, failing the mapping.

This patch adds the created allocator to the allocation query either

With it, there's no need to set the modified allocator's size in the
pool configuration.
https://bugzilla.gnome.org/show_bug.cgi?id=774782
We should set the correct buffer size when we are configuring the pool,
otherwise the buffer will be discarded when it returns to the pool.
Indeed when the ref-count of a buffer reaches zero, its pool will queue
it back (and ref it) if, and only if, the buffer size matches the
configured buffer size on the pool.
This issue can be debugged with GST_DEBUG=*PERF*:6, see gstbufferpool.c

When calling gst_vaapi_video_memory_copy() the allocator of the memory
to copy should be allocated by the vaapi allocator.
This patch does this verification.
Instead of having a gst_vaapi_video_memory_free() that is only going to
be called by gst_vaapi_video_allocator_free(), let's just remove the first
and merged into the second.
There were duplicated code in gst_video_meta_unmap_vaapi_memory() and
gst_vaapi_video_memory_unmap() when unmapping.
This patch refactors both methods adding the common function
unmap_vaapi_memory(). This also ensures, if direct rendering is enabled, it
is correctly reset.
Additionally, only when mapping flag has the WRITE bit, it set the image as
current, which was done in gst_video_meta_map_vaapi_memory() but no in
gst_vaapi_video_memory_map().
In order to make this, the mapping flags were required, so instead of
overloading mem_unmap() virtual function, mem_unmap_full() is overloaded.

Previously the frame map counter increased independently if the map succeeded

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.
https://bugzilla.gnome.org/show_bug.cgi?id=773593
Enable the direct rendering with linear surfaces if the negotiated src caps
are video/x-raw without features.
Pass also the caps, since they are needed to know the requested caps features.
Just as we did in ensure_sinkpad_allocator(), let's move the error message
into the ensure_srcpad_allocator() from the caller,
gst_vaapi_plugin_base_decide_allocation()
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
library.
