Contains the libavcodec version, the VAAPI version and the libva
driver vendor string.

Send buffering_period and pic_timing messages when in modes
targetting bitrate.  Also adds NAL HRD parameters to VUI.

Supports aspect ratio, colour format and timing information.

This avoids duplicating the table in the gsm template file.
Also adjust the table type to uint8_t to save space.

This avoids the danger that get_bits.h might get indirectly #included before
BITSTREAM_READER_LE is defined.

Also sort headers into canonical order where appropriate.

Only the little-endian variant of the table is ever used.

According to avcodec.h, avcodec_decode_video2 should return the number of
bytes used if a frame was decoded.

The current implementation returns size - used size of all the subframes.
This fixes the VLC's bug https://trac.videolan.org/vlc/ticket/16836.

The superframe is always fully consumed.

With compilers that do not support proper dead code elimination, like
Sun C 5.12, linking fails due to missing references to unavailable,
but also unused, symbols.

Bug-Id: 895

Generate the files in a single postprocessing step w/o intermediate files.

Split version files into one line per symbol/directive to allow compatibility
with the Solaris linker without preprocessing and eliminate $ from version file
templates to simplify the postprocessing shell command.

These warnings conflict with system macros on Solaris, producing
truckloads of warnings about macro redefinition.

Experimental; requires Skylake and VAAPI 0.39.1 (not yet released).
Also increases the allowed range of the quality option - in low-power
mode, the Intel driver supports levels 1-8 (and 0 meaning default).

Non-reference frames (nal_ref_idc == 0) should be discardable, so
frame_num does not advance after them.  Before this change, a stream
containing unreferenced B-frames would be rejected by the reference
decoder.

This prevents attempts to use unsupported modes, such as low-power
H.264 mode on non-Skylake targets.  Also fixes a crash on invalid
configuration, when trying to destroy an invalid VA config/context.

This is a video test and there are no audio packets in the sample
anyway.

The current code modifies the user-supplied string, which is shared for
the whole output file. So a bitstream filter specification applied to
multiple streams would not work correctly.
