[MPlayer-users] mplayer cache option greatly reduces performance

Hi. Thanks for quick answer.

"-cache-seek-min" doesn't seem to have any effect. Your point was,
mplayer often seeks, so "0" value should stop it from waiting for the
buffer to fill, right? It seeks, that's true:
******************************************
Out of boundaries... seeking to 0x10471800
Out of boundaries... seeking to 0x3E000  
Out of boundaries... seeking to 0x10471800  
Out of boundaries... seeking to 0x40800  
******************************************
but for some reason "-cache-seek-min 0" doesn't help. I also tried
other values from 1 to 99.

"-demuxer mov" makes it a little faster, but just a little. For
example, with "-cache 8192" I have only laggy video and no sound. With
"-demuxer mov -cache 8192" I already have some sound, and it's playing
a little faster, but still laggy and desyncing.
Rare lags occur with "-cache 20000" and higher with or without
"-demuxer mov"
