2017-03-17swresample/resample: do not assert compensation_distance on rebuild_filterMuhammad Faiz
when set_compensation is called with zero sample_delta, compensation does not happen (because dst_incr == ideal_dst_incr) but compensation_distance is set regression since 01ebb57c03abde89bca7bdbc552917efcb8f551d Found-by: wm4 <nfxjfg@googlemail.com> Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: Muhammad Faiz <mfcc64@gmail.com>

2016-11-26swresample/soxr: fix invalid use of linear_interpMuhammad Faiz
give very bad quality for soxr resampler. linear_interp is intended for using linear interpolation between filter bank so quality will be better. i guess this is misunderstood as 'do not use filter bank, but directly interpolate linearly between samples'.

high phase_count is only useful when dst_incr_mod is non zero in other word, it is only useful on soft compensation on init, it will build filter with low phase_count but when soft compensation is enabled, rebuild filter with high phase_count this approach saves lots of memory Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Muhammad Faiz <mfcc64@gmail.com>
