Stream Decode - mad-dev

20 May 2008


      Hi!
I have the following question - is it possible to decode a stream using MAD?
For example: I have shoutcast stream and I read it in small portions 
(say, 40960 bytes), decode it and encode back to mp3 using LAME
(chaning bitrate, samplerate, etc...).
The problem is that I have to call mad_stream_buffer with each piece of 
stream data, decode/encode it and then if I listen the resulting mp3 
file - I notice "noise" between theese small decoded pieces.
Seems like it happen not only with VBR files.
Pseudo-code:
while ( bytes = read(file_id, buff, SHOUT_BUFFER_LENGTH ) )  {
mad_stream_buffer(&stream, buff, bytes );
while(1){
    mad_frame_decode(&frame,&stream)
    ....
    int ret = lame_encode_buffer( lameGlobalFlags,
                              left,
                              right,
                              nsamples,
                              mp3Buf,
                              mp3Size );
    // Play resulting mp3 data
}
}
Is it possible to decode a stream without theese "edge effects" ? May be 
I should not re-initialize MAD buffer after each read in some way?
Please help.
