Hello,

Which library are you using for Mplayer ? libcdio or the libs included in cdparanoia ?
Apart from the apparent (in)activity on both projects, what are the good reasons to choose one rather than the other ?

mplayer ebuild:
Code:

# libcdio support: prefer libcdio over cdparanoia
# don't check for cddb w/cdio
if use cdio; then
   myconf+=" --disable-cdparanoia"
else
   myconf+=" --disable-libcdio"
   use cdparanoia || myconf+=" --disable-cdparanoia"
   use cddb || myconf+=" --disable-cddb"
fi

if you have both flags on, mplayer ebuild will choose libcdio.

You are right sebaro.
From the ebuild, it's ovious that mplayer prefers libcdio.
But I had read somewhere that it was a question of libcdio / cdparanoia project relative activity.
What I was wondering was if there were other (technical) reasons for preferring one over the other.

Having used mplayer with both, I recall with cdparanoia it seemed flaky at best, whereas cdio works perfectly for me, also I think cddb only works with libcdio, not cdparanoia...

That is exactly the impression I had under FreeBSD. And, as I was not caring much about cddb, that is why I was a little puzzled by leaving cdparanoia for libcdio.

Thank you Hopeless and GWilliam for reporting your experience. I will follow you and opt for libcdio.

according http://www.gnu.org/s/libcdio/
libcdio already includes support for applications which depend on cdparanoia. So my choose is libcdio.

PostPosted: Thu Jul 12, 2012 7:49 am    Post subject: ..and what about abcde, libcdio or cdparanoia? Reply with quote

So reading that website of libcdio it seems that the project already includes its own cdparanoia, the command is not as mentioned there "cd-paranoia" but "/usr/bin/libcdio-paranoia", at least for dev-libs/libcdio-0.83.
Now I wonder if media-sound/abcde-2.5.3 can deal with that...-> Ripping CD-A with abcde, libcdio or cdparanoia?

Now I wonder if media-sound/abcde-2.5.3 can deal with that since it is calling cdparanoia ...and it cannot:
Code:
$ abcde
which: no cdparanoia in (/usr/local/bin:/usr....

Is the new libcdio-paranoia compatible, so I would just set $CDPARANOIA or $CDPARANOIAOPTS?
So far I would continue using the old cdparanoia for abcde only, since libcdio is the better one for mplayer(2).

Massimo ...

I'm still using abcde-2.5.2 ... and haven't tried using libcdio. However, abcde.conf can be configured with the following variables:

Code:
CDROMREADERSYNTAX=cdparanoia
CDPARANOIA=cdparanoia 
CDPARANOIAOPTS="--never-skip=40"

The first of these deals with 'syntax' abcde will expect to encounter (cdparanoia could be replaced with cdda2wav, flac, dagrab, and possibly others). The second is the 'path' to the execuatble (in this case, cdparanoia) but I imagine /usr/bin/libcdio-paranoia could stand in place. The third are options passed to the application (which may help if something needs to be passed to libcdio-paranoia).

So, with the above it may be fairly staightforward to have libcdio-paranoia replace cdparanoia, please let us know how you get on.

HTH & best ...

You probably just don't have cdparanoia installed. Check. :)

There is a use flag that you can enable that will install cdparanoia and help prevent a little extra cruft in your world file.

Code:
~ $ emerge -pv media-sound/abcde

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] media-sound/abcde-2.5.3  USE="aac cdparanoia flac vorbis -id3 -lame -musicbrainz -normalize -replaygain -speex" 0 kB


I just ripped a bunch of CDs with abcde and it worked fine. (with cdparanoia)

lbcdio (and friends) were created because of the lagging and developer issues in cdparanoia. As a general rule, we recommend that one, and more apps are starting to use it as well. We did switch it to default for mplayer because of it's improvements.

In all practical cases, though, use what works best for you.

Code:
CDPARANOIA=libcdio-paranoia
works fine.
Additionally cdparanoia needs to be emerged with USE="-cdparanoia". With this configuration abcde is already using libcdio. Since the interface is quite equal to old cdparanoia it seems to work well with the new libcdio-paranoia.
Code:
Grabbing track 02: Wild World...
cdparanoia III release 9.8 libcdio 0.83 x86_64-pc-linux-gnu
(C) 2001 Monty <monty@xiph.org> and Xiphophorus
(C) 2004, 2005, 2008 Rocky Bernstein <rocky@gnu.org>

Report bugs to bug-libcdio@gnu.org

Ripping from sector   17540 (track  2 [0:00.00])
     to sector   32572 (track  2 [3:20.32])

Anyway after removing media-sound/cdparanoia abcde is failing with
Code:
which: no cdparanoia in (/usr/local/bin:/usr/bin:/bin:/...)
which: no icedax in (/usr/local/bin:/usr/bin:/bin:/...)
which: no icedax in (/usr/local/bin:/usr/bin:/bin:/...)
[ERROR] abcde: icedax is not in your path.
[INFO] Define the full path to the executable if it exists on your system.

Somehow it still checks for old cdparanoia while already using the libcdio. This is solved by additional:
Code:
CDROMREADERSYNTAX=cdparanoia

I guess when leaving this unset abcde is checking for the right backend by checking the PATH for cdparanoia. If found it uses $CDPARANOIA anyway which is a bit wrong. So setting CDROMREADERSYNTAX to cdparanoia avoids the check and expects any cdparanoia named $CDPARANOIA available.

For supporting libcdio for the future it would be nice to introduce CDROMREADERSYNTAX=libcdio. I'm going to forward our discussion here to the developer...
