This way, they look like regular code, which is easier to
understand.

Use of this wrapper was removed in a previous patch, but I
forgot to actually remove the function itself.

This fixes the warning:
libavformat/options.c:62:1: warning: missing braces around initializer [-Wmissing-braces]

Rename it to AVDictionary, since it will be used as such.  Tags
documentation and metadata conversion API is lavf-specific, so remains
there.

The options -loglevel LEVEL -debug FLAGS can be used for achieving the
same objectives, with a finer level of control.

Use -vismv 1 instead. Simplify.

Change indentation and whitespace; also move HAVE_YASM blocks.

The AC-3 encoder unconditionally references some symbols from the E-AC-3
encoder; make those references conditional to fix linking.

read_sequence_header can change width/height; therefore, re-initialize
all tables if width/height changed

Deprecate av_get_bits_per_sample_fmt(), which was a misnamed function.

For the moment we don't have sample formats with a non-integer number
of bytes, in that case we may need to create a new
av_get_bits_per_sample() function. In the meanwhile we prefer to adopt
this variant, since avoids divisions by 8 all over the place.

Fixes Ticket269

The current filter implementation should only have the cx coefficients
divided by gain in order to give the correct output scale.

They are hacks added to reuse the same scaling function for
different formats and they may cause problems when SIMD
implementation of the same functions are used along with pure
C functions.

Make yuv2yuvX16_c a function pointer for yuv2yuvX(), so that the
function pointer becomes bitdepth-independent.

It was errouneously changed to "NTSC" by the recent merge commit.

The option is disabled by default, so enabling it should be documented.

Use av_get_pix_fmt_name() rather than access
av_pix_fmt_descriptors. Improve readability.
