Comment 5 for bug 109849

Can someone confirm exactly the following behaviour?

1.) Open sound-juicer
2.) open Edit > Settings/Preferences > Change audio profiles...

(NOTICE: The menu which opens now, is " gnome-audio-profiles-properties ". It's not a sound-juicer specific settings box)

3.) make 2 new testprofiles, e.g. mp3withmux and mp3withoutmux
for the first (with xingmux):
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc preset=1001 ! xingmux ! id3v2mux

for the second:
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc preset=1001 ! id3v2mux

optional make a third when you have proper ffmpeg-packages installed (ffmux workaround):
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc preset=1001 ! ffmux_mpeg ! id3v2mux

For all these enter a description and check that filename ending is declared as mp3
and check that the checkbox in the bottom left corner is set to "Active".

OK, fine. You will now have these 2 or 3 new profile in your gnome-audio-profiles-properties box. There are shown correctly and have been made active. (If you want you can even check this with gconf-editor simply search for "pipeline").

4.) Now leave the menu which brings you back to sound-juicer settings. Leave this menu also. And to be sure restart sound-juicer once.

5.) Now just > Edit > Settings/Preferences
This time do not click on "change audio profiles" (which woul lead to the audio-profiles-menu).
Because we've already done
we now want to select one of the new profiles by selecting it in the "Format"-section in the sound-juicer-specific (!) dialogue...

6.) Ooops, you will see, that only the profile without xingmux will appear in this selection. Perhaps the one with ffmux will also be available.

CONCLUSION:
In sound-juicer you will NOT be able to select a profile which includes "xingmux" in any way. Though strange, that it appears with no errors in gnome-audio-profiles-properties

Second, the profile/pipeline with ffmux_mpeg will make sometimes correct mp3 information. But also very often totally wrong length information.

The one without ffmux and without xingmux will create most often corrupt mp3 meta tags.

These mp3s are shown totally wrong (concerning the length) in totem, nautilus, rhythmbox and (with the worst effect) in serpentine. Serpentine takes these wrong lengths and you will be happy to get nearly ten songs on a 80min CD.

POSSIBLE WORKAROUND:
Forget about VBR for a while and try pipelines with CBR settings. Though this can be annoying.

It's sad but mp3 still is "standard" for most people. Good quality VBR-mp3s are mostly needed for portable players, usb-sticks etc, party CDs and so one.

The wrong metafiles affecting standard apps like rhythmbox, totem, nautilus and serpentine and won't let them work correctly.

Though mp3 can't be supported officially by ubuntu, let's hope, that this will get fixed till hardy. :-)
