Port of af_volume from FFmpeg, plus improvements and x86 optimization.
Justin Ruggles (8):
af_volume: convert input/ouput list compound literals to named
objects
af_volume: add an option to use a certain precision in the volume
scaling
af_volume: support planar sample formats
af_volume: limit maximum scale based on the sample format.
af_volume: optimize float scaling using
AVFloatDSPContext.vector_fmul_scalar()
x86: af_volume: add SSE4-optimized s16 volume scaling
float_dsp: add vector_dmul_scalar() to multiply a vector of doubles
x86: af_volume: add SSSE3/SSE4/AVX-optimized s32 volume scaling
Stefano Sabatini (1):
lavfi: add volume filter
