This patch adds the handling of VAEncMiscParameterTypeQualityLevel,
in gstreamer-vaapi encoders:
The encoding quality could be set through this structure, if the
implementation supports multiple quality levels. The quality level set
through this structure is persistent over the entire coded sequence, or
until a new structure is being sent. The quality level range can be queried
through the VAConfigAttribEncQualityRange attribute. A lower value means
higher quality, and a value of 1 represents the highest quality. The quality
level setting is used as a trade-off between quality and speed/power
consumption, with higher quality corresponds to lower speed and higher power
consumption.
The quality level is set by the element's parameter "quality-level" with a
hard-coded range of 1 to 8.
Later, when the encoder is configured in run time, just before start
processing, the quality level is scaled to the codec range. If
VAConfigAttribEncQualityRange is not available in the used VA backend, then
the quality level is set to zero, which means "disabled".
All the available codecs now process this parameter if it is available.

Sometimes gst_vaapi_window_wayland_sync returns FALSE when poll returns EBUSY

In this case, if GstVaapiWindow is using vpp, leak of vpp surface happens.

When the frame listener callbacks 'done', the number of pending
frames are decreased. Nonetheless, there might be occasions where
the buffer listener callbacks 'release', without calling previously
frame's 'done'. This leads to problem with
gst_vaapi_window_wayland_sync() operation.
This patch marks as done those frames which were callbacked, but if
the buffer callbacks 'release' and associated frame is not marked
as 'done' it is so, thus the number of pending frames keeps correct.

Fix leakage of the last wl buffer.
VAAPI wayland sink needs to send a null buffer while destruction,
it assures that all the wl buffers are released. Otherwise, the last
buffer's callback might be not called, which leads to leak of
GstVaapiDisplay.
This was inspired by gstwaylandsink.

The proxy object of wl_buffer for the last frame remains in the
wl_map. Even though we call wl_buffer_destroy() in
frame_release_callback(), the proxy object remains without being
removed, since proxy object is deleted when wayland server sees the
delete request and sends 'delete_id' event.
We need to call roundtrip before destroying event_queue so that the
proxy object is removed. Otherwise, it would be mess up as receiving
'delete_id' event from previous play, when playing in the next
va/wayland window with the same wl_display connection.

When the function gst_vaapi_encoder_get_surface_formats() was added
it was under the assumption that any VA profile of the specific codec
supported the same format colors. But it is not, for example the
profiles that support 10bit formats.
In other words, different VA profiles of a same codec may support
different color formats in their upload surfaces.
In order to expose all the possible color formats, if no profile is
specified via source caps, or if the encoder doesn't have yet a
context, all the possible VA profiles for the specific codec are
iterated and their color formats are merged.
https://bugzilla.gnome.org/show_bug.cgi?id=771291
In order to get the supported surface formats within a specific
profile this patch adds the GstVaapiProfile as property to

Instead of creating (if it doesn't exist, yet) the encoder's context

In order to get the GstVaapiChromaType value, also it was needed to
add a new utility function: to_GstVaapiChromaType(), which, given a
VA_RT_FORMAT_* will return the associated GstVaapiChromaType.

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.

Only supporting vaapidecode ! vaapisink combination for now.
Missing dependencies:
1: No support for P010 video format in GStreamer
2: No support for P010 vaGetImage()/vaPutimage() in vaapi-intel-driver
3: As a result of 1&2 , we have no support for Vaapi Video memory mapping
through GstVideoMeta.
Right now we only set chroma format (YUV420 with more than 8 bits per channel)
for surface pool and keeping GST_VIDEO_FORMAT as ENCODED. The underlying format
of the surfaces is implementation (driver) defined, which is P010.
This new API gst_vaapi_surface_pool_new_with_chroma_type() is for
creating a new GstVaapiVideoPool of GstVaapiSurfaces with the specified
chroam type and dimensions. The underlying format of the surfaces is
implementation (driver) defined.
When receiving the texture from the application or the video sink, we must
know it size and border. To query the texture the API has changed according to
the OpenGL version used in the GL context of the application/vsink.
This patch checks the current context API type and queries the texture
according to this detected API.

Unlike other decoders, vp9 decoder doesn't need to reset the
whole context and surfaces for each resolution change. Context
reset only needed if resolution of any frame is greater than
what actullay configured. There are streams where a bigger
resolution set in ivf header or webm header but actual resolution
of all frames are less. Also it is possible to have inter-prediction

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.
This is useful for notifying the upper layer, or downstream elements,
that the decoded frame may contain artefacts.

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

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).
https://bugzilla.gnome.org/show_bug.cgi?id=745048
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.

Now when thread 2 comes in and sees g_drm_device_type is RENDERNODES, it queues

Practically we should be able to support more formats, for eg:
JPEG Encoder can support YUV422, RGBA and all.
But this is causing more issues which need proper fix here and there.
Otherwise the condition could become true before the lock
is taken and the g_cond_signal() could be called
before the g_cond_wait(), so the g_cond_wait() is never
awoken.

Add support for GEM buffer imports. This is useful for VA/EGL interop
with legacy Mesa implementations, or when it is desired or required to
support outbound textures for instance.

Add new gst_vaapi_surface_new_with_dma_buf_handle() helper function
to allow for creating VA surfaces from a foreign DRM PRIME fd. The
resulting VA surface owns the supplied buffer handle.
https://bugzilla.gnome.org/show_bug.cgi?id=735362
Add gst_vaapi_surface_new_from_buffer_proxy() helper function to
create a VA surface from an external buffer provided throug the
new GstVaapiBufferProxy object.
Add support for GEM buffer exports. This will only work with VA drivers
based off libdrm, e.g. the Intel HD Graphics VA driver. This is needed
to support interop with EGL and the "Desktop" GL specification. Indeed,
the EXT_image_dma_buf_import extension is not going to be supported in
Desktop GL, due to the lack of support for GL_TEXTURE_EXTERNAL_OES targets
there.
This is useful for implementing VA/EGL interop with legacy Mesa stacks,
in Desktop OpenGL context.

Use the new VA buffer export APIs to allow for a VA surface to be
exposed as a plain PRIME fd. This is in view to simplifying interop
with EGL or OpenCL for instance.
https://bugzilla.gnome.org/show_bug.cgi?id=735364
The VA buffer export APIs work for a particular lifetime starting from
vaAcquireBufferHandle() and ending with vaReleaseBufferHandle(). As such,
it could be much more convenient to support implicit releases by simply
having a refcount reaching zero.

Reword surface pool allocation helpers so that to allow for a simple
form, e.g. gst_vaapi_surface_pool_new(format, width, height); and a
somewhat more elaborated/flexible form with optional allocation flags
and precise GstVideoInfo specification.
This is an API/ABI change, and SONAME version needs to be bumped.
Add GstVaapiDisplay::get_{visual_id,colormap}() helpers to help determine
the best suitable window visual id and colormap. This is an indirection in
view to supporting EGL and custom/generic replacements.
Add GstVaapiWindowClass::get_colormap() hook to help determine the
currently active colormap bound to the supplied window, or actually
create it if it does not already exist yet.
Add GstVaapiWindowClass::get_visual_id() function hook to help find
the best suitable visual id for the supplied window. While doing so,
also simplify the process by which an X11 window is created with a
desired Visual, i.e. now use a visual id instead of a Visual object.
Add a new generic helper function gst_vaapi_window_new() to create
a window without having the caller to check for the display type
himself. i.e. internally, there is now a GstVaapiDisplayClass hook
to create windows, and the actual backend implementation fills it in.
Add new generic helper functions gst_vaapi_texture_new_wrapped()
This is a simplification in view to supporting EGL.
Add gst_vaapi_display_has_opengl() helper function to help determining
whether the display can support OpenGL context to be bound to it, i.e.
if the class is of type GST_VAAPI_DISPLAY_TYPE_GLX.
Make gst_vaapi_display_get_display_type() return the actual VA display
type. Conversely, add a gst_vaapi_display_get_class_type() function to
return the type of the GstVaapiDisplay instance. The former is used to
identify the display server onto which the application is running, and
the latter to identify the original object class.
Record the underlying native display instance into the toplevel
GstVaapiDisplay object. This is useful for fast lookups to the
underlying native display, e.g. for creating an EGL display.
Add new generic helper functions gst_vaapi_texture_new_wrapped()
and gst_vaapi_texture_new() to create a texture without having
the caller to uselessly check for the display type himself. i.e.
internally, there is now a GstVaapiDisplayClass hook to create
textures, and the actual backend implementation fills it in.
This is a simplification in view to supporting EGL.
GstVaapiTexture is a generic abstraction that could be moved to the
core libgstvaapi library. While doing this, no extra dependency needs
to be added. This means that a GstVaapitextureClass is now available
for any specific code that needs to be added, e.g. creation of the
underlying GL texture objects, or backend dependent ways to upload
a surface to the texture object.
Generic OpenGL data types (GLuint, GLenum) are also replaced with a
plain guint.

The VA/GLX interfaces are obsolete. They used to exist for XvBA, and
ease of use, but they had other caveats to deal with. It's now better
to move on to legacy mode, whereby VA/GLX interop is two be provided
through (i) X11 Pixmap, and (ii) other modern means of buffer sharing.
https://bugzilla.gnome.org/show_bug.cgi?id=736711
The gst_vaapi_texture_put_surface() function is missing a crop_rect
argument that would be used during transfer for cropping the source
surface to the desired dimensions.
Note: from a user point-of-view, he should create the GstVaapiTexture
object with the cropped size. That's the default behaviour in software
decoding pipelines that we need to cope with.
This is an API/ABI change, and SONAME version needs to be bumped.
https://bugzilla.gnome.org/show_bug.cgi?id=736712
Add new gst_vaapi_surface_new_full() helper function that allocates
VA surface from a GstVideoInfo template in argument. Additional flags
may include ways to
- allocate linear storage (GST_VAAPI_SURFACE_ALLOC_FLAG_LINEAR_STORAGE) ;
- allocate with fixed strides (GST_VAPI_SURFACE_ALLOC_FLAG_FIXED_STRIDES) ;
- allocate with fixed offsets (GST_VAAPI_SURFACE_ALLOC_FLAG_FIXED_OFFSETS).
Add new gst_vaapi_surface_proxy_new() helper to wrap a surface into
a proxy. The main use case for that is to convey additional information
at the proxy level that would not be suitable to the plain surface.
Re-introduce a GST_VAAPI_ID_INVALID value that represents
a non-zero and invalid id. This is useful to have a value
that is still invalid for cases where zero could actually
be a valid value.
Make it possible to have all libgstvaapi backends (libs) access to a
common GstVaapiMiniObject API and implementation. This is a minor step
towards full exposure when needed, but restrict it to libgstvaapi at
this time.
Really report sample aspect ratio (SAR) as present, and make it match
what we have obtained from the user as pixel-aspect-ratio (PAR). i.e.
really make sure VUI parameter aspect_ratio_info_present_flag is set
to TRUE and that the indication from aspect_ratio_idc is Extended_SAR.
This is a leftover from git commit a12662f.

Fix gst_vaapi_decoder_mpeg4_parse() to initialize the packet type to
GST_MPEG4_USER_DATA so that a parse error would result in skipping
that packet. Also fix gst_vaapi_decoder_mpeg4_decode_codec_data() to
initialize status to GST_VAAPI_DECODER_STATUS_SUCCESS.
Use the SEI pic_timing() message to track and propagate down the repeat
first field (RFF) flag. This is only initial support as there is one
other condition that could induce the RFF flag, which is not handled
yet.
Fix the decoding process for picture order count type 0 when the previous
picture had a memory_management_control_operation = 5. In particular, fix
the actual variable type for prev_pic_structure to hold the full bits of
the picture structure.
In practice, this used to work though, due to the underlying type used to
express a gboolean.
Use the SEI pic_timing() message to track the pic_struct variable when
present, or infer it from the regular slice header flags field_pic_flag
and bottom_field_flag. This fixes temporal sequence ordering when the
output pictures are to be displayed.

Add support for DRM Render-Nodes. This is a new feature that appeared
in kernel 3.12 for experimentation purposes, but was later declared
stable enough in kernel 3.15 for getting enabled by default.
This allows headless usages without authentication at all, i.e. usages
through plain ssh connections is possible.
Fix gst_vaapi_surface_proxy_copy() to copy the view-id element, thus
fixing random frames skipped when vaapipostproc element is used in
passthrough mode. In that mode, GstMemory is copied, thus including
the underlying GstVaapiVideoMeta and associated GstVaapiSurfaceProxy.
Ensure the X11 implementation for GstVaapiWindow::get_geometry() is
thread-safe by default, so that upper layer users don't need to handle
that explicitly.
Add gst_vaapi_window_reconfigure() interface to force an update of
the GstVaapiWindow "soft" size, based on the current geometry of the
underlying native window.
This can be useful for instance to synchronize the window size when
the user changed it.
Thanks to Fabrice Bellet for rebasing the patch.
[changed interface to gst_vaapi_window_reconfigure()]

Add gst_vaapi_display_get_display_name() helper function to determine
the name associated with the underlying native display. Note that for
raw DRM backends, the display name is actually the device path.
