[MPlayer-users] Problems with mplayer on PPC

Hi,

what file type? DVD (LPCM in VOB), AVI or WAV ?

  if(sh_audio->format==0x736F7774){ // "twos" is swapped byteorder
    int j;
    for(j=0;j<len;j+=2){
      char x=buf[j];
      buf[j]=buf[j+1];
      buf[j+1]=x;
    }
  }

it's in ad_pcm.c
try to change the if() to negative, so:

  if(sh_audio->format!=0x736F7774){ // "twos" is swapped byteorder
...

and tell me if it's ok now

wma - no, only DLl cdoec for wma audio
wmv - depending on codec, for mpeg4 v2,v3 you can use libavcodec, vor wmv1/2
you can't yet
