272b252c01 rv40dsp: implement prescaled versions for biweight.
Quite often, the original weights are multiple of 512. By prescaling them
by 1/512 when they are computed (once per frame), no intermediate shifting
is needed, and no prescaling on each call either.

The x86 code already used that trick.

e652cc9606 rv34: use get_bits_left()
It is not necessary to store the bit stream length in a RV34DecContext
field.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

84dc2d8afa Remove DECLARE_ALIGNED_{8,16} macros
These macros are redundant.  All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

its stride and offset to always have align 4.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.

987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
