Reading through this thread I think I might add some ideas for an
alternative approach.

cd-discid also provides the number of tracks (2nd field) to populate a
playlist before the rip has even started.

This is where that playlist would come into play, obviously.

Just to be clear, when you say 'player' you mean mplayer?

Also, you can have cdparanoia rip to individual WAV files with -B. The
naming scheme is documented in the man page. With the information
gathered from cd-discid you should be able to create the playlist and
start playback when the first file hits your desired threshold size.

Encoding can start as soon as the first track will have been ripped.

You can delete the file while it is playing already. The name will
disappear from the filesystem, but the inode will stay as long as
mplayer has it open.

There is only one problem I see with playing the ripped WAV file, be it
with your approach or any other. If cdparanoia takes longer to rip it
than the play time, due to defects and resulting error handling,
playback in mplayer will stop prematurely due to EOF at some point.
If you play it as cdda:// that should not happen, but exhibit skips or

On a side note, in another reply you said, that cvlc works with
.wav/.cue. Is there a specific reason not to use it then for your
