From 02b4964346686a2e50f75d57a22b4cb209c259b9 Mon Sep 17 00:00:00 2001 From: Andre Noll Date: Mon, 28 Feb 2011 14:05:31 +0100 Subject: [PATCH] audiod: Update --no_default_filters help text. This was quite outdated: We got the defaults right for udp and dccp streams at least since commit 28f8405e (April 2010). Moreover, two new audio formats (wma and spx) are supported now but are not mentioned in the help text. Describe that the corresponding decoder is used as the default filter rather than listing all supported audio formats. --- ggo/audiod.m4 | 31 ++++++++++++++++--------------- 1 file changed, 16 insertions(+), 15 deletions(-) diff --git a/ggo/audiod.m4 b/ggo/audiod.m4 index 289917c3..2659b93a 100644 --- a/ggo/audiod.m4 +++ b/ggo/audiod.m4 @@ -136,22 +136,23 @@ option "no_default_filters" D #~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Configure filters manually" flag off -details=" +details = " If (and only if) this option is set, the --filter options - (see below) take effect.
