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

This patch improves performance when glimagesink uploads a GL texture.
It caches the GStVaapiTexture instances in GstVaapiDisplay{GLX,EGL}, using an
instance of GstVaapiTextureMap, so our internal texture structure can be found
by matching the GL texture id for each frame upload process, avoiding the
internal texture structure creation and its following destruction.

This basically reverts 62c3888b76 (wayland:
decouple wl_buffer from frame).
Otherwise the frame may be overwritten while it is still used by the
compositer:
The frame done callback (frame_done_callback()) is called, when the
compositor is done processing the frame and hands it to the hardware.
The buffer release callback (frame_release_callback()) is called when the
buffer memory is no longer used.
This can be quite some time later: E.g. if weston (with the DRM backend)
puts the buffer on a hardware plane, then then buffer release callback is
called when the kernel is done with the buffer. This is usually when the
next frame is shown, so most likely after the frame done callback for the
next frame!
Since 70eff01d36 "wayland: sync() when
destroy()" the mentioned possible leak should no longer be a problem, so
reverting this change should cause no leaking buffers.

Improve closure of gaps in frame_num by strictly following and trying
to fill them with previous reference frames. So, they are now tracked
thus avoiding insertion of dummy ("greenish") frames.
If the new picture to be added to the DPB is not a first field, then
it shall be the second field of the previous picture that was added
before.
This removes the need for dpb_find_picture() now that we track the
immediately preceding decoded picture, in decode order.
When a dummy "other-field" is inserted, it is assumed to inherit the
reference flags from the first field, and the sliding window decoded
reference picture marking process is also executed so that corrupted
frames are moved out as early as possible.
While doing so, we also try to output frames that now contain a single
valid field picture, prior to inserting any other picture into the DPB.
Note: this may be superfluous currently based on the fact that dpb_add()
combines the two most recent pairable fields, but this process would be
further simplified later on.
Mark the picture as "corrupted" if it is reconstructed from corrupted
references or if those references are fake, e.g. resulting from lost
frames.

that the decoded frame may contain artefacts.

Try to identify missing first fields too, thus disregarding any
intermediate gaps in frames. We also assume that we keep the same
field sequence, i.e. if previous frames were in top-field-first
(TFF) order, then so are subsequent frames.
Note that insertion of dummy first fields need to operate in two
steps: (i) create the original first field that the current field
will inherit from, and (ii) submit that field into the DPB prior
to initializing the current (other) field POC values but after any
reference flag was set. i.e. copy reference flags from the child
(other field) to the parent (first field).

Interlaced H.264 video frames always have two fields to decode and
display. However, in some cases, e.g. packet loss, one of the field
can be missing. This perturbs the reference picture marking process,
whereby the number of references available in DPB no longer matches
the expected value.
This patch adds initial support for missing field within a decoded
frame. The current strategy taken is to find out the nearest field,
by POC value, and with the same parity.
https://bugzilla.gnome.org/show_bug.cgi?id=745048
Try to maintain a "top-field-first" (TFF) flag, even if the H.264 standard
does not mandate it. This will be useful for tracking missing fields, and
also for more correct _split_fields() implementation for frames in the DPB.
Don't try to decode pictures until the first I-frame is received within
the currently active sequence. There is no point is decoding and then
displaying frames with artifacts.
Fix decoding of end_of_seq() NAL unit so that to not submit the current
picture for decoding again. This is pretty vintage code that dates back
before the existing of the whole decoder units machinery.
One issue that could be arising if that code was kept is that we could
have submitted a picture, and subsequently a GstVideoCodec frame, twice.
Once without the decode_only flag set, and once with that flag set. The
end result is that the GstVideoDecoder would release the codec frame
twice, thus releasing stale data.
In short, the piece of code that is removed by this patch is for once
completely obsolete for a while, and secondly error-prone in corner
cases.
If the GOP temporal sequence number (TSN) is interpolated from a valid
PTS, then we need to compensate that PTS corresponding to the start of
GOP with the next picture to be decoded, which shall be an I-frame,
based on its sequence number.

Before pushing a the new frame, the render() method calls sync() to flush the
pending frames. Nonetheless, the last pushed frame never gets rendered, leading
to a memory leak too.
This patch calls sync() in the destroy() to flush the pending frames before
destroying the window.
Also a is_cancelled flag is added. This flag tells to not flush the event
queue again since the method failed previously or were cancelled by the user.

Otherwise wl_display_dispatch_queue() might prevent the pipeline from
shutting down. This can happen e.g. if the wayland compositor exits while
the pipeline is running.
Changes:
* renamed unlock()/unlock_stop() to unblock()/unblock_cancel() in gstvaapiwindow
* splitted the patch removing wl_display_dispatch_queue()

wl_display_dispatch_queue() might prevent the pipeline from shutting
down. This can happen e.g. if the wayland compositor exits while the
pipeline is running.
This patch replaces it with these steps:
- With wl_display_prepare_read() all threads announce their intention
to read.
- wl_display_read_events() is thread save. On threads reads, the other
wait for it to finish.
- With wl_display_dispatch_queue_pending() each thread dispatches its
own events.
wl_display_dispatch_queue_pending() was defined since wayland 1.0.2

Since frame in the private data means the last frame sent, it would
semantically better use last_frame.
Also, this patch makes use of g_atomic_pointer_{compare_and_exchange, set}()
functions.

Wayland window has a pointer to the last pushed frame and use it to set the
flag for stopping the queue dispatch loop. This may lead to memory leaks,
since we are not keeping track of all the queued frames structures.
This patch removes the last pushed frame pointer and change the binary flag
for an atomic counter, keeping track of number of queued frames and use it for
the queue dispatch loop.

This patch takes out the wayland's buffer from the the frame structure. The
buffer is queued to wayland and destroyed in the "release" callback. The
frame is freed in the surface's "done" callback.
In this way a buffer may be leaked but not the whole frame structure.
- surface 'done' callback is used to throttle the rendering operation and to
unallocate the frame, but not the buffer.
- buffer 'release' callback is used to destroy wl_buffer.

This patch fixes several issues found when running the `make distcheck`
target:
- In commit c561b8da, the update of gstcompat.h in Makefile.am was
forgotten.
- In commit c5756a91 add the simple_encoder_source_h in EXTRA_DIST was
forgotten.
- vpx.build.stamp is not generated at all, only vpx.configure.stamp.
- The make target distcleancheck failed because some autogenerated files
were not handled with the DISTCLEANFILES variable.
Note: `make distcheck -jXX` is not currently supported.
GST_VAAPI_ENCODER_STATUS_NO_SURFACE and GST_VAAPI_ENCODER_STATUS_NO_BUFFER
are not errors, so they do not have the ERROR namespace.
This patch fixes this typo in documentation.
On s390x, guintptr and GstVaapiID are not compatible types. The
implementation of gst_vaapi_window_new_internal() and all its callers
seem to assume that its third argument is a GstVaapiID, while the
header gives it guintptr type.

Since bug #745728 was fixed the oldest supported version of GStreamer is
1.2. That GStreamer release requires glib 2.32, so we can upgrade our
requirement too.
This patch changes the required version of glib in configure.ac and removes
the hacks in glibcompat.h

This patch only intends to improve readability: in the method
gst_vaapi_window_wayland_sync() the if/do instructions are squashed into a
single while loop.
Also renames the frame_redraw_callback() callback into frame_done_callback(),
which is a bit more aligned to Wayland API.
The Wayland compositor may still use the buffer when the frame done
callback is called.
This patch destroys the frame (which contains the buffer) until the
release callback is called. The draw termination callback only controls
the display queue dispatching.

There is a race condition where g_drm_device_type can be left set to
DRM_DEVICE_RENDERNODES when it shouldn't.
If thread 1 comes in and falls into the last else statement setting up both
RENDERNODES and LEGACY types. And begins to process the first type (RENDERNODES),
it sets g_drm_device_type = RENDERNODES.
Now when thread 2 comes in and sees g_drm_device_type is RENDERNODES, it queues
up that type to be tried but then encounters the lock and has to wait until the
first thread finishes. Once the lock is acquired it will then proceed to ONLY try
RENDERNODES and fail it. But it doesn't try LEGACY. And from then on, all future
attempts will only try RENDERNODES.
So to avoid this situation I have simply moved the acquisition of the lock higher
up in the attached patch.

The video pool can be accessed with the display lock held, for example,
when releasing a buffer from inside vaapisink_render, but allocating
a new object can may also take the display lock. Which means a possible
deadlock.

The support for buffer exports in VA-API was added in version 0.36. These
interfaces are for interop with EGL, OpenCL, etc.
GStreamer-VAAPI uses it for a dmabuf memory allocator. Though, gstreamer-vaapi
has to support VA-API versions ranging from 0.30.4, which doesn't support it.
This patch guards all the buffer exports handling (and dmabuf allocator) if
the detected VA-API version is below 0.36.
