0670acc4f1 dca_parser: Extend DTS core sync word and fix existing check
The previous version checked for 14-bit streams and did not properly
work across buffer boundaries.

Use the 64-bit parser state to make extended sync word detection work
across buffer boundary and check the extended sync word for 16-bit LE
and BE core streams to reduce probability of alias sync detection.

94c20de429 avcodec/libx265: use x265 Multi-library Interface to query the API
ffmpeg can now use the x265 multi-library interface to make a runtime
selection between a number of libx265 libraries (perhaps 8bpp and 16bpp).

ffmpeg will link to one build of libx265 (statically or
dynamically) and this linked version of libx265 will support one
bit-depth (8 or 10 bits). At runtime, ffmpeg now has the option to request the
encoder to use a different bit depth(8 or 10). If the requested bitdepth
is zero, or if it matches the bitdepth of the system default libx265 (the
currently linked library), then this library will be used for encode.
If ffmpeg requests a different bit-depth, the linked libx265 will attempt
to dynamically bind a shared library with the requested bit-depth from the install
location (default or user-specified).

new x265 API:
     const x265_api* api = x265_api_get(int bitDepth);
     x265_api - holds the libx265 public API functions
     bitDepth - requested API for 8bpp or 16bpp

     note: Use 0 to indicate native bit depth of the linked libx265 and
           x265_api_get(0) is guaranteed to return a non-null pointer

AV_PIX_FMT_GRAY8/16 are considered YUV formats, and the color_range is

the API user adds a special-case for the PNG decoder.)

These are later used as block_w and block_h arguments of
s->vdsp.emulated_edge_mc. If one of them is 0 it triggers an av_assert2
in emulated_edge_mc:
    av_assert2(start_x < end_x && block_w > 0);

bb2cb0a66d quickdraw: Switch to greedy parsing
Quickdraw packs data as a series of codes that the application is supposed
to handle, but it does not define any order in which they might appear.
Since it's unfeasible to support *all* opcodes defined by the spec,
only handle well-known blocks containing video data and ignore any unknown
or unsupported ones.

Move palette loading and rle decoding to separate functions to resue them
in other blocks and drop format initialization in init since it can
support more formats than pal8.

Validate width and height.

372aa0777a pngdec: don't use AV_PIX_FMT_MONOBLACK for apng
AV_PIX_FMT_MONOBLACK has the AV_PIX_FMT_FLAG_BITSTREAM flag, i.e.
linesize can be smaller than width.

Since x_offset is only check against the width, this can lead to
x_offset * bpp >= image_linesize.

In this case ptr could be set to a position outside the image_buf in
png_handle_row, leading to memory corruption and thus crashes.

Check extended sync word for 16-bit LE and BE core streams to reduce
probability of alias sync detection. Previously sync word extension was
checked only for 14-bit streams (and this check did not properly work
across buffer boundary).

Use 64-bit parser state to make extended sync word detection work across
buffer boundary.

This is sufficient to make the sample in ticket #4492 parse
successfully.

ee62b364be h264: eliminate ff_h264_set_parameter_from_sps()
That function currently does two things -- reinitializing the DSP
contexts and setting low_delay based on the SPS values.

The former more appropriately belongs in h264_slice_header_init(), while
the latter only really makes sense in decode_slice_header().

The third call to ff_h264_set_parameter_from_sps(), done immediately
after parsing a new SPS, appears to serve no useful purpose, so it is
just dropped.

Also, drop now unneeded H264Context.cur_chroma_format_idc.

Currently, the DPB is initialized in alloc_tables() and uninitialized in

variables, so DPB management does not logically belong in there.

Since we want the init/uninit to happen exactly once per the context
lifetime, init_context()/free_context() are the proper place for this
code.
