I made quite a few changes based on suggestions on IRC, as well as
replies in the previous thread. Most of the patches are now squashed
since very little of the original cherry-picked code still remains.
Justin Ruggles (6):
float_dsp: add vector_dmul_scalar() to multiply a vector of doubles
eval: treat dB as decibels instead of decibytes
lavu/opt: do not filter out the initial sign character except for
flags
lavfi: add volume filter
x86: af_volume: add SSE2-optimized s16 volume scaling
x86: af_volume: add SSSE3/AVX-optimized s32 volume scaling
