069083a419 ac3enc: clip coupling coordinates during calculation
This is faster than using the clip_coefficients() function. Also,
clipping the coordinates before determining reuse is better since it
will compare coordinates that are closer to their final encoded values.

9791c02733 Saner RV1/2 initialisation and RV2 header parsing.
Old version was based on lots of guesswork which had different hacks based on
32-bit version field instead of splitting it into major/minor/micro version.
RV2 picture header parser also had a few places where it deviated from binary

Stefano Sabatini
fdd130a213 prefer "SAR" over "PAR" in av_dump_format()
"SAR" (Sample Aspect Ratio) is globally preferred over "PAR" (Pixel
Aspect Ratio), although the two terms share the same semantics.

For example the corresponding AVStream field is called
sample_aspect_ratio, and libavfilter has a filter named setsar.

Therefore prefer the term "SAR" over "PAR" in the
libavformat/utils.c:dump_stream_format() and avcodec_string() output
for avoiding confusion.

2968bedf12 bink: make IDCT take 32-bit input
Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical
for most codecs, move Bink IDCT into separate context. Get rid of an additional
permutation table while at it since SIMD support for Bink IDCT is unlikely to
be implemented in foreseeable future.
Quantisation tables also have to change type to signed for proper
dequantisation of DCT coefficients.

e324619ca9 imgconvert: change logic in avcodec_get_pix_fmt_loss()
Avoid the use of the brittle/inconsistent information in
PixFmtInfo.depth, and implement a possibly more robust logic which
exposes the information in pixdesc.

Also allow the removal of PixFmtInfo.depth, since this is the only use
of it.

da4c7cce21 x86: fix build with gcc 4.7
The upcoming gcc 4.7 has more advanced constant propagation
resulting some inline asm operands becoming constants and thus
emitted as literals, sometimes in contexts where this results
in invalid instructions.

This patch changes the constraints of the relevant operands
to "rm" thus forcing a valid type.  While obviously suboptimal,
this is what older gcc versions already did, and there is no
change to the code generated with these.

7cbb856efe Remove useless NULL check.
We dereferenced the pointer two lines above, no point in
checking for NULL afterwards.
In addition it cannot be NULL the way it was initialized
just one line further above.

d7e14c0d10 imgconvert: remove PixFmtInfo.pixel_type field
The field is only used for checking if a format is YUV planar
and if the format is paletted.

This patch replaces the current is_planar_yuv() code with a function
which uses the pixdesc information. The new implementation is less
efficient, but this should not be an issue as the functions which use
it (av_picture_crop/pad()) are deprecated and currently never used in
the codebase.

3b8bb503ee imgconvert: store padded size information in PixFmtInfo, simplify avg_bits_per_pixel()
Prefer data-driven over procedural logic in avg_bits_per_pixel(),
simplify and improve robustness, as it is easy to miss a function
update when a new format is added.
