From 57e462a04fe8aec74bb8f625bdfa5d7d2b3e3d46 Mon Sep 17 00:00:00 2001 From: arpi Date: Sat, 21 Dec 2002 22:16:49 +0000 Subject: Presets are an easy way, to use hard to access lame options and to give you optimum quality at average bitrate. This patch adds presets to mencoder for libmp3lame >= 3.92.
