Add gst_vaapi_get_config_attribute() helper function that takes a
GstVaapiDisplay and the rest of the arguments with VA types. The aim
is to have thread-safe VA helpers by default.
Make sure to configure the encoder with the set of packed headers we
intend to generate and submit. i.e. make selection of packed headers
to submit more robust.
Cache the first compatible GstVaapiProfile found if the encoder is not
configured yet. Next, factor out the code to check for the supported
rate-control modes by moving out vaGetConfigAttributes() to a separate
function, while also making sure that the attribute type is actually
supported by the encoder.
Also fix the default set of supported rate control modes to not the
"none" variant. It's totally useless to expose it at this point.
Introduce GstVaapiContextUsage so that to explicitly determine the
usage of a VA context. This is useful in view to simplifying the
creation of VA context for VPP too.
Unknown attributes, or attributes that are not supported for the given
profile/entrypoint pair have a return value of VA_ATTRIB_NOT_SUPPORTED.
So, return failure in this case.
Move GstVideoOverlayComposition handling to separate source files.
This helps keeing GstVaapiContext core implementation to the bare
minimal, i.e. simpy helpers to create a VA context and handle pool
of associated VA surfaces.
Improve documentation and debug messages. Clean-up APIs, i.e. strip
them down to the minimal set of interfaces. They are private, so no
need expose getters for instance.
Make sure that libgstvaapi private headers remain internally used to
build libgstvaapi libraries only. All header dependencies were reviewed
and checks for IN_LIBGSTVAAPI definition were added accordingly.
Also rename GST_VAAPI_CORE definition to IN_LIBGSTVAAPI_CORE to keep
consistency.
Bump the library major version due to API/ABI changes that occurred in
the imaging API. In particular, GstVaapiDisplay interfaces no longer
expose any GstCaps but provide GArray based ones e.g. to determine the
set of supported decode/encode profiles.
Set a valid GstVideoCodecFrame.system_frame_number when decoding a
stream in standalone mode. While we are at it, improve the debugging
messages to also include that frame number.
When decoding failed, or that the frame was dropped, the associated
surface proxy is not guaranteed to be present. Thus, the GST_DEBUG()
message needs to check whether the proxy is actually present or not.

Don't emit NAL HRD parameters for now in the SPS headers because the
SEI buffering_period() and picture_timing() messages are not handled
yet. Some additional changes are necessary to get it right.
https://bugzilla.gnome.org/show_bug.cgi?id=722734
Fix default CPB buffer size to something more reasonable (1500 ms)
and that still fits the level limits. This is a non configurable
property for now. The initial CPB removal delay is also fixed to
750 ms.
https://bugzilla.gnome.org/show_bug.cgi?id=722087
Round down the calculated, or supplied, bitrate (kbps) into a multiple
of the HRD bitrate scale factor. Use a bitrate scale factor of 64 so
that to have less losses in precision. Likewise, don't round up because
that could be a strict constraint imposed by the user.
Fix the level calculation involving bitrate limits. Since we are
targetting NAL HRD conformance, the check against MaxBR from the
Table A-1 limits shall involve cpbBrNalFactor depending on the
active profile.
Submit sequence parameter buffers only once, or when the bitstream
was reconfigured in a way that requires such. Always submit packed
sequence parameter buffers at I-frame period, if the VA driver needs
those.
https://bugzilla.gnome.org/show_bug.cgi?id=722737
Make sure to submit the packed headers only if the underlying VA driver
requires those. Currently, only handle packed sequence and picture
headers.
https://bugzilla.gnome.org/show_bug.cgi?id=722737
The VAEncSequenceParameterBuffer.ip_period value reprents the distance
between the I-frame and the next P-frame. So, this also accounts for
any additional B-frame in the middle of it.
This fixes rate control heuristics for certain VA drivers.
https://bugzilla.gnome.org/show_bug.cgi?id=722735
Fix level characterisation when the bitrate is automatically computed
from the active coding tools. i.e. ensure the bitrate once the profile
is completely characterized but before the level calculation process.
Document and rename a few functions here and there. Drop code that
caps num_bframes variable in reset_properties() since they shall
have been checked beforehand, during properties initialization.
Clean-up GstBitWriter related utility functions and simplify notations.
While we are at it, also make bitstream writing more robust should an
overflow occur. We could later optimize for writing headers capped to
their maximum possible size by using the _unchecked() helper variants.
Drop private header since it was originally used to expose internals
to the plugin element. The proper interface is now the properties API,
thus rendering private headers totally obsolete.
This maps GstVideoColorimetry information in vaapisink's sinkpad caps
to GST_VAAPI_COLOR_STANDARD_* flags, if per-buffer information was not
available.

before the pipeline has been set to PLAYING, the display has not yet

For non "Constant-QP" modes, we could provide more reasonable heuristics
for the target bitrate. In general, 48 bits per macroblock with all the
useful coding tools enable looks safe enough. Then, this rate is raised
