From 425ac31a3b07cbef79891d01a3655b9c6d7efa32 Mon Sep 17 00:00:00 2001 From: wm4 Date: Tue, 18 Sep 2012 21:41:22 +0200 Subject: softvol, ao_pulse: prefer ao_pulse volume control by default --softvol is enabled by default. For most audio outputs, this is a good thing, as they have either their own (bad) soft volume implementation, or control the system mixer. With ao_pulse, the situation is a bit different: it supports per-application volume (i.e. volume control is not really global). More importantly, ao_pulse uses a rather large audio buffer, and changing the volume with mplayer's volume filter has a large delay. With the native ao_pulse volume control, it's instant, because PulseAudio's audio filtering happens at a later stage in its processing pipeline (inaccessible for mplayer). This means native volume control should really be allowed for ao_pulse, while it's the reverse for other audio outputs. Make --softvol a choice option, and add a new "auto" choice. This is default and will use PA's volume control with ao_pulse, and mplayer's volume filter otherwise (i.e. the old softvol behavior). --- DOCS/man/en/options.rst | 16 +++++++++++++--- 1 file changed, 13 insertions(+), 3 deletions(-) (limited to 'DOCS/man') diff --git a/DOCS/man/en/options.rst b/DOCS/man/en/options.rst index 431ff1a7de..653cac9737 100644 --- a/DOCS/man/en/options.rst +++ b/DOCS/man/en/options.rst @@ -1741,9 +1741,19 @@ timing is imprecise and you cannot use the RTC either.
