disksrc -> mp3parse -> mpg123 -> audiosink
|
||
|
|
|
||
|
|
disksrc reads last 4K chunk from disk. Sets EOS on the buffer, pushes buffer out to peer.
|
||
|
|
disksrc:src sets itself to EOS and chains to mp3parse.
|
||
|
|
|
||
|
|
mp3parse takes the buffer and slices it up into several.
|
||
|
|
Each buffer gets chained off to mpg123.
|
||
|
|
|
||
|
|
mpg123 decoders each frame and sends it to audiosink.
|
||
|
|
|
||
|
|
audiosink dumps the audio data to the sound card.
|
||
|
|
|
||
|
|
mpg123 returns from the chain, and returns.
|
||
|
|
|
||
|
|
mp3parse returns from each of the several chains,a nd returns.
|
||
|
|
|
||
|
|
disksrc:src returns from the chain, signals EOS, and sets disksrc's EOS flag
|
||
|
|
|
||
|
|
At this point the pipeline state code takes over and starts to set everyone to READY
