I already had a (rather superficial) look at that, yes. The problem is
that so far I don't have an idea how to decode/play the data read from
the media. The example coming with libcdio (cdda-player) relies on a
direct audio connection between the drive and the sound device, thus
does not help. I could use aqualung as an example, but this is not
really easy to understand.
I had the idea of giving up on CDPlayer and instead integrate this
functionality into Cynthiune. Here the playing part already exists, i.e.
it seems to be "only" necessary to extract the PCM data from the CD and
pass it to the next stage. Unfortunately, Cynthiune seems rather
unmaintained (some of the backends can't be compiled anymore as
necessary libraries have changes their APIs). Thus, I don't know whether
it was a good idea. As you can imagine I am not too keen on taking over
maintenance of that app considering that I already neglect CDPlayer :-)
As for portability, as far as I understand, libcdio should be available
and working on most flavours of Un*x.
