Fix reference picture marking process with memory_management_control_op
set to 3 and 6, i.e. assign LongTermFrameIdx to a short-term reference
picture, or the current picture.
This fixes decoding of FRExt_MMCO4_Sony_B.

The initialization of reference picture lists (8.2.4.2) applies to all
slices. So, the RefPicList0/1 lists need to be constructed prior to
each slice submission to the HW decoder.
This fixes decoding of video sequences where frames are encoded with
multiple slices of different types, e.g. 4 slices in this order I, P,
I, and P. More precisely, CABAST3_Sony_E and CABASTBR3_Sony_B.

When NAL units of type 13 (SPS extension) or type 19 (auxiliary slice)
are present in a video, decoders shall perform the (optional) decoding
process specified for these NAL units or shall ignore them (7.4.1).
Implement option 2 (skip) for now, as alpha composition is not
supported yet during the decoding process.
This fixes decoding of the primary coded video in alphaconformanceG.

When MVC slice NAL units (coded slice extension and prefix NAL) are
present, the number of NAL header bytes is 3, not 1 as usual.

At the time the first VCL NAL unit of a primary coded picture is found,
and if that NAL unit was parsed to be an SPS or PPS, then the entries
in the parser may have been overriden. This means that, when the picture
is to be decoded, slice_hdr->pps could point to an invalid (the next)
PPS entry.
So, one way to solve this problem is to not use the parser PPS and
SPS info but rather maintain our own activation chain in the decoder.

Retain the SEI messages that were parsed from the access unit until we
have completely decoded the current frame. This is done so that we can
peek at that data whenever necessary during decoding. e.g. for exposing
3D stereoscopic information at a later stage.
Fix support for grayscale encoded video clips, and possibly others if
the underlying driver supports the non-YUV 4:2:0 formats. i.e. defer
the decision that a surface with the desired chroma format is not
supported to the actual VA driver implementation.
https://bugzilla.gnome.org/show_bug.cgi?id=728144
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.
