hello,

i wrote my own source-client and i have a crazy problem. i stream my vorbis-files with the following code:

Code:
    if( stream_get_filebyid( &mysql, item->value, file ) == TRUE ) {
      if( sprintf( trackpath, "../data/%s", file ) ) {
        fd_file = fopen( trackpath, "r" );
       
        while( item ) {
          int retval = fread( buffer, 1, sizeof( buffer ), fd_file );
         
          if( retval > 0 ) {
            if( shout_send( this->shout, ( unsigned char* ) buffer, retval ) != SHOUTERR_SUCCESS )
              break;
           
          } else {
            if( ( item = item->child ) == NULL ) {
              if( this->repeat == TRUE )
                item = playlist_get_rootitem( this->playlist );
             
              else
                break;
            }
           
            if( stream_get_filebyid( &mysql, item->value, file ) == FALSE )
              break;
           
            if( !sprintf( trackpath, "../data/%s", file ) )
              break;
           
            fd_file = freopen( trackpath, "r", fd_file );
          }
         
          shout_sync( this->shout );
        }
      }
    }


if the stream switches to an other track ( if the current track is at EOF ) many player ( like mplayer, rythembox, totem ) stop playing or play crazy noise. few player like vlc and xmms work fine with my stream. whats the problem? it is a bug on mplayer an the other players or is my code not ok?

hard to to know 100% but the fact that icecast doesn't have a problem and you have seen at least 2 players that don't have an issue would indicate that those non-working players have some trouble with new headers.

okay, i have tested ezstreamer and ices2 and ezstreamer have the same problem like my application. i think the difference between these three applications is the method of send data. my application and ezstreamer use shout_send() and ices2 uses shout_send_raw(). so i have to use shout_send_raw() to solve this problem or whats your view? is there a better example application than ices2 because ices2 is very extensive as example. and what means raw - i have to send http-data too?

The _raw function is for sending without libshout doing any verification or timing on it. For ices2, with multiple stream outputs having timing on the outgoing end was pointless, as the timing is controlled by the input engine.

Besides that, if using ices2 shows that those same players have the same problem then I don't see why changing to the _raw function will help. If the problem really is new headers then they are useless for streaming and the developers of those apps should be notified.
