8effd68975 build: add LIBVA_WAYLAND_CFLAGS to libgstvaapiegl
In case libva-wayland has its headers not installed in default
locations (like /usr/include), the build fails to include "wayland-client.h":

   CC       libgstvaapi_egl_la-gstvaapiutils_egl.lo
 In file included from gstvaapidisplay_wayland.h:27:0,
                  from gstvaapidisplay_egl.c:35:
 /usr/include/va/va_wayland.h:31:28: fatal error: wayland-client.h: No such file or directory
  #include <wayland-client.h>

As we already passed VA_CLAGS, /usr/include/va/va_wayland.h could be found, but it is
our fault not to instruct the system that we ALSO care for va_wayland. We correctly query
for libva-wayland.pc in configure and use this in other places as well. It is thus only
correct and consequent, to do it also at this spot.

This patch ensures to get the formats, as filter does, available in the

The context fills up the array as soon it is created, otherwise the pipeline

d1581ba557 libs: move get_surface_formats to utils_core
The query of all the supported formats for a VA config were only used by the
postprocessor (vaapifilter). But, in order to enable the vaapidecoder to
negotiate a suitable raw format with downstream, we need to query these
formats against the decoder's config.

This patch is the first step: moves the code in filter's ensure_image() to a
generic gst_vaapi_get_surface_formats() in vaapiutils_core, so it can be
shared later by the decoder.

185da3d1a4 libs: display: GstVaapiDisplay as GstObject descendant
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.

abc2480b10 libs: minor correction for logical consistency
GstVaapiDecode is a descendant of GstVaapiMiniObject, so, thought we should

GstVaapiPixmap, GstVaapiTexture and GstVaapiWindow are descendant of
GstVaapiObject, hence its methods shall be used.

a80e10ac5c libs: display{egl,glx}: cache GstVaapiTextures
instances when created and reuse

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.

2eb439416d decoder: vc1: Fail only on actual interlaced frames
In the earlier patch:

 f31d9f3 decoder: vc1: Print error on interlaced content

Decoding would error out if the interlace flag was set in the
sequence bdu. This isn't quite right because a video can have this
flag set and yet not have any interlaced pictures.

Here instead we error out when either parsing a field bdu or
decoding a frame bdu which has fcm set to anything other than
progressive.

b64eaaad4d libs: x11: allows 30-bit colour depth
The colour depth is clamped to 24 when it is not equal {15,16,24,32}. But this
fails with the NVIDIA binary driver as it doesn't advertise a TrueColor visual
with a depth of 24 (only 30 and 32). Allowing the depth to be 30, lets everything
work as expected.

Copy the data into the dependent slice segment header from the
corresponding independent slice segment header during parsing.

Previously the reference to the "previous" independent header was
held through the parsing phase and then dereferenced during the
decoding phase. This caused all dependent headers to be populated
with the data of the AU's last independent header instead of the
proper corresponding header.

e4ed64b731 wayland: free the frame in frame_release_callback()
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.

When a dummy "other-field" is inserted, it is assumed to inherit the

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.

1b76561d95 vaapidecoder: no wmv profiles gstreamer 1.4/1.2
This patch fix the auto-plugging problem in gstreamer 1.2 and gstreamer 1.4

Right now there is not a primary ranked parser for vc1 and the demuxers
delivers caps without specifying the profile. This situation is not an issue
for avdec_vc1 but for vaapidecode it is, which refuses to negotiate without a
explicit profile defined in the negotiated caps.

Nonetheless, in gstreamer 1.5 it seems not to be a problem since the
negotiation admits caps subsets try outs.

This patch solves the issue ignoring the profile negotiation in the caps. For
gstreamer < 1.5 the profile string is not handled, so the auto-plugging get
done without the vc1 parser, such as happens in gstreamer 1.5.

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

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).

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.

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.

e60df073a0 window: Correct prototype to match implementation
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.

81d6b42420 build: upgrade glib dependency to 2.32
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

af8ea3701e wayland: refactor _sync() method and rename callback
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.

7548c72a7d wayland: free frame in buffer release callback
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.

The base class needs to be informed about frames that were still queued
in the decoder on release, otherwise they are leaked.

b5425da1de display: drm: fix race condition setting device type
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.

0adb36b658 videopool: Release lock while allocating new object
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.
