[Libcdio-devel] OpenBSD vs libcdio vs Audacious

[Edd Barrett]

Hi,

I've found some time to look into the audacious issues.

It turns out the situation with audacious isn't as bad as I first
thought. I thought it was erroneously starting the CD on a different
track each time, but this turned out to be the shuffle feature being
enabled! Doh!

Nonetheless, there are some errors being printed on the console. For
each error message in the driver, I've added printing __func__ so we can
see what causes it. I've also added a load of other debugging messages.

If I click services->play cd:

And the CD is playing. Errors here:

 * Looks like the player might be checking if the disc is a DVD and we get an
   error. Might be OK?

 * Fetching the first sector of a track always makes an SCSI error. I can see
   this when I skip tracks too.

   CD is playing, then we skip track, wait a moment, and skip again:

Another thing I notice is when I stop playback, the player seems to be checking
if the disc is a DVD once a second. Weird, but maybe OK.

Other than these error messages, cd playback seems fine, even with CDs with
non-one start tracks.

I'd be interested to hear what you guys think, if anything, about these error
messages. Maybe some of the SCSI details mean something to Thomas, for example?

Next I'll look at mpv (which has deeper issues I think).
