Try pre8 please My bad - this has nothing to do with mplayer. It was actually toolame, enough though it has not changed in three years (last release 2003-03-01). Of course my old system that it use to run fine on was 32-bit whilst my new system is 64-bit - oh dear, how embarrasing.... Sorry for the noise. |

(NOTE: I don't think the problem is with toolame - what I'm trying to do use to work and toolame has not changed for a couple of years now) Simple work around is to use the "nowaveheader" option and then tell toolame what the sample frequency is, i.e. #> mplayer -ao pcm:nowaveheader -vo null -vc dummy output.avi <...> #> toolame -s 48 -p 2 -b 384 audiodump.wav output.mp2 No header found.
