[Libcdio-devel] Status: Rock Ridge, ISO9660 and audio controls

Just to let folks know where things stand. Handling Rock Ridge
extensions seems complete (for now). I have not been able to find a
gap that is missing, although I have no doubt looking at GNU/Linux
code there may be more subtleties down the line.

I have found one problem in handling ISO 9660 filesystems. For the
directory reading, I've been using a new routine I added
read_data_blocks() which is supposed to do the right thing whether a
sector is mode 1 or mode 2 format. In all cases except OSX (where MMC
isn't handled), I've been using a generic MMC routine for this. And
aside from OSX, I'm not sure I know how to do this other than via
MMC. For reasons I don't understand when a large number of blocks
needs to get read, this routine hangs and causes CD resets and then
eventually fails. I've tried to reduce the number of blocks read in
one shot without success.

Although I haven't checked anything into CVS, I've started adding
audio controls to libcdio. As is my pattern I start with GNU/Linux and
then other OS's get filled out.
