Thread: [PATCH] Fixed wavpack 9-15 bits support

git-svn-id: file:///var/local/repositories/ffmpeg/trunk@18666 9553f0bf-9b14-0410-a0b8-cfaf0461ba5b

Display dimensions should not affect the real size of coded frame, thus set
only avctx->{width,height} and don't touch coded_{width,height} when parsing
them. This fixes the case when coded and display dimensions differ by more
than one macroblock.

PPC asm for AV_RL*()

PPC is normally big endian but has special little endian load/store
instructions.  Using these avoids a separate byteswap.  This makes the
vorbis decoder about 5% faster.  Not much else uses little-endian
read/write extensively.

GCC generates horrible PPC code for the default AV_[RW]B64 (which uses
a packed struct), so we override it with a plain pointer cast.

git-svn-id: file:///var/local/repositories/ffmpeg/trunk@18602 9553f0bf-9b14-0410-a0b8-cfaf0461ba5b

ARM asm for AV_RN*()

ARMv6 and later support unaligned loads and stores for single
word/halfword but not double/multiple.  GCC is ignorant of this and
will always use bytewise accesses for unaligned data.  Casting to an
int32_t pointer is dangerous since a load/store double or multiple
instruction might be used (this happens with some code in FFmpeg).
Implementing the AV_[RW]* macros with inline asm using only supported
instructions gives fast and safe unaligned accesses.  ARM RVCT does
the right thing with generic code.

This gives an overall speedup of up to 10%.
