[MPlayer-dev-eng] [PATCH] ao_null and audio-only

[Reimar Döffinger]

Hi,
this patch should fix the insane (>90%) CPU usage when playing e.g. MP3 with
-ao null.
Also, it seems correct to me as the aos should round the len parameter
of the play function to a number divisible by outburst, so 0 and anything < outburst are effectively the same...

Greetings,
Reimar Döffinger
