From 222899fbbe523320e66ae1600fabe45b58d48686 Mon Sep 17 00:00:00 2001 From: Jan Janssen Date: Fri, 17 Mar 2017 16:49:28 +0100 Subject: af_drc: remove Remove low quality drc filter. Anyone whishing to have dynamic range compression should use the much more powerful acompressor ffmpeg filter: mpv --af=lavfi=[acompressor] INPUT Or with parameters: mpv --af=lavfi=[acompressor=threshold=-25dB:ratio=3:makeup=8dB] INPUT Refer to https://ffmpeg.org/ffmpeg-filters.html#acompressor for a full list of supported parameters.
