From e8abba5f43a2383c8020c23bfa88f8d9d7998dab Mon Sep 17 00:00:00 2001 From: bircoph Date: Sun, 3 May 2009 21:51:37 +0000 Subject: Support for libbs2b ver. 3.0.0 API. Now filter parameters are highly controllable, virtually all audio formats are supported, and new profiles are available. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@29244 b3059339-0415-0410-9bf9-f77b7e298cf2 --- DOCS/man/en/mplayer.1 | 24 ++++++++++-- libaf/af_bs2b.c | 102 ++++++++++++++++++++++++++++++++++++++++---------- 2 files changed, 102 insertions(+), 24 deletions(-) diff --git a/DOCS/man/en/mplayer.1 b/DOCS/man/en/mplayer.1 index 90ef00b1e6..f5b1f4999e 100644 --- a/DOCS/man/en/mplayer.1 +++ b/DOCS/man/en/mplayer.1 @@ -5067,10 +5067,26 @@ head shadowing effect.
