Don't force allocation of VA surfaces in YUV 4:2:0 format. Rather, allow
for the upper layer to specify the desired chroma type. If the chroma
type field is not set (or yields zero), then YUV 4:2:0 format is used
by default.
Fix possible bug when a per-segment deblocking filter level value
needs to be set in non-absolute mode, i.e. when the loop filter update
value is negative in delta mode.
Also clamp the resulting filter level value to 0..63 range.
Improve condition to disable the loop filter. The previous heuristic
used to check all filter levels, for all segments. It turns out that
only the base filter_level value defined in the frame header needs
to be checked.
This fixes 00-comprehensive-013.
Fix generation of source tarballs when certain conditionals are not
met. e.g. always include all buildable codecparsers sources in the
distribution tarball, fix plug-in element sources set to include X11
and encoder bits.
The built-in libvpx serves multiple purposes, among which the most
important ones could be: track the most up-to-date, and optimized,
range decoder; allow for future hybrid implementations (non-VLD);
and have a completely independent range decoder implementation.
Apply correct patch from fd.o #722760 to fix several issues: update the
license terms to LGPLv2.1+, fix dependencies to built-in libvpx and fix
make dist.
Add libvpx submodule that tracks the upstream version 1.3.0. This is
needed to build a libgstcodecparsers_vpx.so library with all symbols
placed into the GSTREAMER namespace.
The gst_h264_parse_parse_sei() function now returns an array of SEI
messages, instead of a single SEI message. Reason: it is allowed to
have several SEI messages packed into a single SEI NAL unit, instead
of multiple NAL units.

Fix parser and decoder state to sync at the right locations. This is
because we could reset the parser state, while the decoder state was
not copied yet, e.g. when parsing several NAL units from multiple frames
whereas the current frame was not decoded yet.
This is a regression brought in by commit 6fe5496.
It turns out it is more convenient to have only pkgconfig files named
after the installed GStreamer API version (1.0) instead of using all
possible subsequent names from that (1.0, 1.2, 1.4). i.e. they conflict
altogether anyway, so align pkgconfig file names to that.
Fix gstreamer-vaapi includedir for GStreamer 1.2 setups. i.e. use
the pkgconfig version (1.0) instead of the intended API version (1.2).
libgstvaapi1.0-dev and libgstvaapi1.2-dev packages will now conflict,
as would core GStreamer 1.0 and GStreamer 1.2 dev packages anyway.
Try to improve package description for the compiled plug-in elements
available in there. e.g. only display vaapidownload and vaapiupload
for GStreamer 0.10 builds, display vaapiencode_* elements when VA
encoding is enabled, etc.
Also increase the copyright notice date.
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.
