Bugzilla Bug 113716

It seems Nero uses more tools than those specified in the ebuild.. Looking into
default .nerorc file we can see (choosen only specific lines) eg.

suffix=.ogg
detectsize=oggtst "$file"

suffix=.shn
filtername=shorten -x|sox -t .wav - -t .raw -r 44100 -w -x -c 2 -s -
detectsize=shntool len "$file"

suffix=.wav
encoder=sox -t .raw -r 44100 -w -x -c 2 -s - -t .wav "$file"

suffix=.mp3
settitle=mp3info -t "$title" -a "$artist" "$filename"
encoder=lame -b 128 -m j -h - "$file"
filtername=mpg123 -r 44100 -s --stereo -q -

As far as I can see the following dependencies are missing:
.ogg - oggtst
.shn - shntool, sox
.wav - sox
.mp3 - lame, mp3info

Reproducible: Always
Steps to Reproduce:
1.Start Nero
2.Try to build an AudioCD with eg. some .ogg files as a track source
Actual Results:  
Nero will complain about missing oggtst tool to detect size


Expected Results:  
No error/warning message

do you think it would be a good idea to remove those USE flags and hard-depend
on the following.

    media-sound/mpg123
    media-sound/lame
    media-sound/mp3info
    media-sound/vorbis-tools
    media-sound/oggtst
    media-sound/shorten
    media-sound/sox
    media-sound/shntool

?

I think so - it's a part of Nero functionality. If these applications are
missing you won't get full 'audio' functionality..

There will be some users who don't use nero for audio burning (such as myself)
and only ever use it for data/iso burning.

Since there do already seem to be some USE flags (and hopefully gentoo users
know what are they are how they work), perhaps all that's needed is to add the
missing tools to their various USE flags (mp3, vorbis, etc) and also add an
ewarn upon installation informing the user they must set the audio use flags if
they want the full feature set Nero offers?

I would say that they shouldn't be hard dependencies since Nero is essentially
CD burning software, and the audio elements are extra features, which the user
should have the choice of enabling or not.  This sort of situation is precisely
what USE flags are there for, allowing the user the choice...

I also tend to vote yes for the USE flag solution, as those programs are just
the preconfigured defaults for dealing with audio stuff. They aren't required
to run the program, also one could theoretically use completely different tools
for that.

So, if no one reports any grave reasons why not to do it that way, I will
incorporate the needed changes into the package within the next couple of days,
along with some einfo output describing the situation.

Thanks for your participation, guys.

I don't really mind having USE flags unless I can enable everything (extra 8
packages) through them..

I'm sorry to pester, but is there any news on this bug, since it's also
blocking another bug which in turn blocks a modular X tracking bug?  It'd be
quite nice to see the latest version of nero come out...

=app-cdr/nero-2.0.0.4 committed.
