From e3d0df70fea5c80baec3a75142ba53b22d3a61b8 Mon Sep 17 00:00:00 2001 From: reimar Date: Thu, 15 Sep 2005 11:41:23 +0000 Subject: Fix af_pan commandline mess and (hopefully) improve description. It should now output the right number of channels and it doesn't silently clamp values to the too restrictive [0, 1] range. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@16494 b3059339-0415-0410-9bf9-f77b7e298cf2 --- DOCS/man/en/mplayer.1 | 14 +++++++++----- 1 file changed, 9 insertions(+), 5 deletions(-) (limited to 'DOCS') diff --git a/DOCS/man/en/mplayer.1 b/DOCS/man/en/mplayer.1 index ff9aa07c13..b27f41d249 100644 --- a/DOCS/man/en/mplayer.1 +++ b/DOCS/man/en/mplayer.1 @@ -3986,18 +3986,22 @@ this filter can be found in the examples section near the end. .PD 0 .RSs .IPs \ \ -number of input channels (1\-6) +number of output channels (1\-6) .IPs -How much of input channel j is mixed into output channel i (0\-1). +How much of input channel i is mixed into output channel j (0\-1). +So in principle you first have n numbers saying what to do with the +first input channel, then n numbers that act on the second input channel +etc. +If you don't specify any numbers for some input channels, 0 is assumed. .RE .sp 1 .RS .I EXAMPLE: .RE .RSs -.IPs "mplayer \-af pan=1:0.5:0.5 \-channels 1 media.avi" +.IPs "mplayer \-af pan=1:0.5:0.5 media.avi" Would down-mix from stereo to mono. -.IPs "mplayer \-af pan=3:1:0:1:0.5:0.5 \-channels 3 media.avi" +.IPs "mplayer \-af pan=3:1:0:0.5:0:1:0.5 media.avi" Would give 3 channel output leaving channels 0 and 1 intact, and mix channels 0 and 1 into output channel 2 (which could be sent to a subwoofer for example). @@ -8963,7 +8967,7 @@ mplayer \-vo zr2 \-vf scale=352:288,zrmjpeg file.avi . .TP .B Play a 6-channel AAC file with only two speakers: -mplayer \-rawaudio on:format=0xff \-af pan=6:.32:.39:.06:.17:-.17:.33:.32:.06:.39:-.17:.17:.33 adts_he-aac160_51.aac +mplayer \-rawaudio on:format=0xff \-af pan=2:.32:.32:.39:.06:.06:.39:.17:-.17:-.17:.17:.33:.33 adts_he-aac160_51.aac .br You might want to play a bit with the pan values (e.g multiply with a value) to increase volume or avoid clipping. -- cgit v1.2.3
