* avcodec/g729postfilter: Clip gain before scaling with AGC_FAC1Michael Niedermayer2020-05-11
| | | | | | | | | | | | The fixed point integer reference specifies the multiplication used to have 16bit input and clips so we need to clip the input The floating point implementation does not seem to do that.
