It is redundant with costable. The first half of sintable is
identical with the second half of costable. The second half
of sintable is negative value of the first half of sintable.

The computation is changed to handle sign of sin values, in
C code and ARM assembly code.

This mode apparently does not support decoding of HEVC Main (8 bit).
With D3D11 and Intel drivers on Windows 10 I get green corruption, while
using DXVA2_ModeHEVC_VLD_Main works.

In url_find_protocol(), proto_str is either "file" or a string
consisting of only the characters in URL_SCHEME_CHARS, which does not
include ','. Therefore the strchr(proto_str, ',') call always returns
NULL.

Note: The code was added in commit
6161c418.

When 'out' is an AVFrame that does not have buffers preallocated,
swr_convert_frame tries to allocate buffers of the right size. However
in calculating this size it failed to check for whether 'in' is NULL
(requesting that swr's internal buffers are to be flushed).

libvorbis comes with pkg-config files since at least v1.0.1, way back in 2003.

We need the two checks for vorbis and vorbisenc because we use functions from
both and Xiph considers them separate libraries.

The check is inverted (vorbis first then vorbisenc) because add_extralibs()
prepends to EXTRALIBS instead of appending. For both shared and static linking
the order didn't seem to matter anyway, testing with MinGW.

Some .srt files use this tag.

(An alternative implementation would be correctly ignoring unknown tags,
and treating them as whitespace. libass can do automatic line wrapping.)
