The function dump_picture_info() has extra braces in the profiles
HEVC_MAIN_444 and VP9. Because of this, the additoinal braces are
added in the trace file generated by the applications like ffmpeg,
mplayer and so on. The client of this generated trace file, like
the python scripts that read this trace file, run into into the
problem of wrongly reading the picture info or incomplete reading
of picture info.
Also, there was a comma missing in the VP9 profile in the
dump_picture_info(). This again creates the problem of generating
a trace file without a comma, which again leads to wrongly reading
the picture info.
To avoid this problem of wrongly reading or incomplete reading of
picture info, extra braces have been removed and an additional
comma is introduced in the dump_picture_info().

Add new profiles present in Range Extension profiles.
A.3.5 in Annexures of HEVC draft mentions of various profiles
Main 12,
Main 444,
Main 444 10/12,
Main 422 10/12,
etc.
under format range extension profiles. All these profiles have single
profile_idc value 4 These are distinguished by additional flags present
in the bistream specified in Table A.2 of HEVC draft.
FFmpeg skips parsing the additional flags and maintains single profile
for all the format range extension profiles. However since various GPU
generations support various features we are adding all the profiles
separately so that support can be specified accurately.
This Change adds the new HEVC profiles in VDPAU.h
Add new VdpPictureInfoHEVCRangeExt picture parameter structure.
As HEVC444 profile falls under RangeExtension profiles, Due to
similarities between Range Extensions profiles, the picture parameter
structure is re-used.
Also Adding new VdpChromaTypes for 16bit.
For 10/12 bit HEVC decoding, the output memory layout will be P010/P012
respectivley which are similar to P016 format i.e. each component is of
2 Byte width (16bit) with MSBs as valid bits as per the format.
Hence adding 16bit surfaces which can accommodate both P010 and P012
formats and can be used for both 10/12 bit decoding.
This Change also adds VDP_YCBCR_FORMAT_P016, VDP_YCBCR_FORMAT_P010 YCrCb
formats to be used by get/put bits functions(transfer functions) to
access the 16Bit Decoded Surface.

The 'install' parameter to the configure_file() function explicitly controls
whether the file is installed, but omitting it just infers whether to install
the file based on the presence or absence of the 'install_dir' parameter. This
parameter requires Meson 0.50 or newer:
WARNING: Project specifies a minimum meson_version '>=0.41' but uses features which were added in newer versions:
* 0.50.0: {'install arg in configure_file'}
We don't need to specify 'install' for this particular file because
'install_dir' is not set, so just remove it to drop the Meson requirement back
down to 0.41.

VdpDecoderQueryProfileCapability API
Chroma types :
VDP_CHROMA_TYPE_420
VDP_CHROMA_TYPE_422
VDP_CHROMA_TYPE_444
already exist, surfaces of these types could be transparently used with
any VdpVideoDecoder. The implementation is free to internally convert
the surface between frame/field(NV12/NV24) as required by
VdpVideoDecoder operation. The interop API would allow registration of
these surfaces for either field or frame based interop.
This change adds new enums for frame and field chroma types:
VDP_CHROMA_TYPE_420_FIELD
VDP_CHROMA_TYPE_422_FIELD
VDP_CHROMA_TYPE_444_FIELD
VDP_CHROMA_TYPE_420_FRAME
VDP_CHROMA_TYPE_422_FRAME
VDP_CHROMA_TYPE_444_FRAME
So that frame/field based video surfaces can be created and exposed via
VDPAU OpenGL interop.
The new chroma types could only be used by a VdpVideoDecoder that
supports output to field/frame surfaces respectively. Internal surface
convertion is not allowed. The interop API would allow registration
of these surfaces to field/frame based interop only. This will avoid
implicit conversions and allocation of shadow surface.
Existing VdpDecoderQueryCapabilities() returns maxlevel, maxwidth,
height and macro blocks for a given decoder profile. Since it is not
possible to extend this API to return more capabilities, adding new API
VdpDecoderQueryProfileCapability(). In this change, new API will be able
to return supported picture structure along with other existing
capabilities.
VdpDecoderQueryProfileCapability() can be extended in future to query
newer capabilities exposed. VdpDecoderCapabilities defines the
capabilities that can be queried.
This function returns queried capability of the requested profile on the
underlying h/w. By design, only one capability can be queried at a time.

This patch is in response to the following security vulnerabilities
(CVEs) reported to NVIDIA against libvdpau:
CVE-2015-5198
CVE-2015-5199
CVE-2015-5200
To address these CVEs, this patch:
- replaces all uses of getenv(3) with secure_getenv(3);
- uses secure_getenv(3) when available, with a fallback option;
- protects VDPAU_DRIVER against directory traversal by checking for '/'
On platforms where secure_getenv(3) is not available, the C preprocessor
will print a warning at compile time. Then, a preprocessor macro will
replace secure_getenv(3) with our getenv_wrapper(), which utilizes the check:
getuid() == geteuid() && getgid() == getegid()
See getuid(2) and getgid(2) for further details.

libvdpau 1.0 contained an error in its HEVC picture info structures. Rather
than try to maintain backward compatibility with the incorrect definition, the
existing VdpPictureInfoHEVC was updated to contain the fixed definition. Since
the new structure is no longer compatible with the ABI defined by libvdpau 1.0,
change the profile numbers for HEVC so that software built against the incorrect
definition will not recognize the new profiles.

An NVIDIA internal hardware document noted:
#define MAX_TILE_COLS 20
#define MAX_TILE_ROWS 22
As of this writing the VDPAU API writes:
/** Only need to set 0..num_tile_columns_minus1. The struct
definition reserves up to the maximum of 22. Invalid values are
ignored. */
uint16_t column_width_minus1[22];
/** Only need to set 0..num_tile_rows_minus1. The struct
definition reserves up to the maximum of 20. Invalid values are
ignored.*/
uint16_t row_height_minus1[20];
This is not correct. The correct definitions ought to be:
uint16_t column_width_minus1[20];
uint16_t row_height_minus1[22];
The H.265 Specification does not give an explicit range for the sizes
of these arrays. It is possible to calculate an upper limit for a particular
video frame implicitly using these equations:
MinCbLog2SizeY = log2_min_luma_coding_block_size_minus3 + 3 (7-10)
CtbLog2SizeY = MinCbLog2SizeY + log2_diff_max_min_luma_coding_block_size (7-11)
CtbSizeY = 1 << CtbLog2SizeY (7-13)
PicWidthInCtbsY = Ceil( pic_width_in_luma_samples ÷ CtbSizeY ) (7-15)
num_tile_columns_minus1 ϵ [0, PicWidthInCtbsY − 1]
(num_tile_rows_minus1 is similar)
For a video with:
log2_min_luma_coding_block_size_minus3 = 0
log2_diff_max_min_luma_coding_block_size = 0
pic_width_in_luma_samples = 4096
num_tile_columns_minus1 < 512
This seems patological. Perhaps we could cap column_width_minus1[] and
row_height_minus1[] at 32 or 64 elements apiece if other hardware
implementations saw a reason to do so.
This change as proposed does not alter the size of VdpPictureInfoHEVC, but
it *does* change the ABI. We can either add it as a fixup to the just
released VDPAU 1.0, or create a follow-on patch structure. Since few have
adopted VdpPictureInfoHEVC since Monday my preference is to fix the
existing structure.

This patch adds an API for player applications to utilize VDPAU for
hardware-accelerated playback of H.265/HEVC streams.
The goals of this API are:
- enable hardware accelerated decoding of H.265/HEVC content under VDPAU;
- provide a reference implementation for H.265/HEVC hardware decoding that
is vendor agnostic;
- provide enough data for H.265/HEVC hardware acceleration implementations
from multiple vendors to be able to use the same API;
This patch is written against "version one" of the H.265/HEVC Specification,
Rec. ITU-T H.265 (04/2013), available at:
http://handle.itu.int/11.1002/1000/12296
A future patch against this header may address bug fixes, and may support
the new features described in "version two" of the H.265/HEVC Specification,
Rec. ITU-T H.265 v2 (10/2014).
Note that the API does need to be self documenting with Doxygen markup,
which we (NVIDIA) will generate and post as an update to our public VDPAU
documentation.
This is version 8 of the patch.
Version 1 was the original version.
Version 2 was a minor cleanup change.
Version 3 incorporated 10- and 12-bit formats.
Version 4 clarified some documentation related to H.265/HEVC support.
Version 5 clarified some documentation related to H.265/HEVC support
and correcting the Specification URI above.
Version 6 further corrected the Specification URI above, re-ordered the
fields in VdpPictureInfoHEVC to agree with the Specification, and added
additional documentation for some fields. It also corrected some cosmetic
indentation errors.
Version 7 removed the sps_sub_layer_ordering_info_present_flag, added a
note on implementing clauses 8.3 through 8.7, clarified the meaning of
sps_max_dec_pic_buffering_minus1, moved the scaling lists to follow
scaling_list_enabled_flag, clarified comments on pps_beta_offset_div2
and pps_tc_offset_div2, and added "Ignored otherwise." or "Invalid
values are ignored" comments to several fields.
Version 8 truncated a number of fields related to reference pictures to
8 bit types, e.g. uint8_t.

Because structures defined in vdpau.h may be used outside of the libvdpau
interface itself, it's important for them to not change, even to add new fields
to the end. Clarify this by tightening the restriction on how structures can be
modified.
This means that we can also *relax* the restriction on versioned structures that
says that they can only be extended by adding fields to the end. As long as
uint32_t struct_version is the first field of the structure, the implementation
can look at that to determine the complete layout of the rest of the fields.

The wrapper, as it's currently written, cannot cope with more than one
VdpGetProcAddress implementation. Luckily, this should hardly ever
happen.
This patch protects access to the _imp_get_proc_address variable to
conform to the memory model, and ensures that a single VDPAU
implementation is used - failing safe if not so.
