Bug Description

Binary package hint: rhythmbox

When I playback an mp3 file using rhythmbox, i get this odd, semi rhythmical thumping noise over the top of the music being played. In case you ask, this is not the actual music, or indeed specific mp3 files. It seems that all mp3 files generate this in rhythmbox.

It is not limited to rhythmbox, but it does appear to be limited to gstreamer applications. Totem generates the same odd sound. Xmms does not generate this problem.

I assigned this bug to rhythmbox because that is where I initially found it, and where other users probably will too. I suspect the bug is actually in the gstreamer0.10-plugins-ugly package.

Sadly I could not find a bug describing this problem in the gstreamer bugzilla. I'm not much good at searching big bugzillas though, someone else should look for it. The upside is that whatever the source of the bug, a more recent gstreamer build eliminates the problem :D

I have been using Jokosher-0.2 for a bit. The script for installing this on ubuntu:
* Grabs a particular cvs version of gstreamer (2006-11-13)
* Builds it in a subdir your home directory
* Sets up environment variables so that you can run Jokosher with the cvs gstreamer without interfering with the Edgy packaged gstreamer. Clever Aq

I just used this to run rhythmbox in the same cvs gstreamer environment, and no more thumping over mp3 playback :D

My request is for a clever person to find and backport the fix gstreamer have made in their cvs 2006-11-13 version. Pleeese.

Confirmed by me & upstream. This is due to a bug in our old gstreamer0.10-fluendo-mp3 and like the original reporter reported, it is fixed upstream.

What does this mean for me as an Edgy user. Do I have to wait for Feisty to get the fix for this, or will the fix be backported?

Do you have any tips on finding the original bug in the gstreamer bugzilla. Would it be worth me going IRC on their asses. Just to politely ask where I could find the fix, then maybe apply it myself.

Alternatively would there be a way to get a backported version of gstreamer. I don't want to break the package dependencies stuff. If there's a backport I'd take that.

as this doesn't cause disrupt the stability or security of ubuntu. i can't see this getting fixed via -updates, possibly -backports. see the changelog for fluendo-mp3 here https://core.fluendo.com/gstreamer/svn/trunk/gst-fluendo-mp3/ChangeLog
i believe 2006-09-06 is the date this was fixed.

this bug is still current in fiesty.

tho in the meantime, feel free to remove the fluendo-mp3 package and enjoy mp3's without the buggyness :)

I believe you are correct on the fix date. The part in the entry log that seems to fit with what I am experiencing is:

"Fix a nasty array index overflow that was resulting in noise in the
 left channel for some builds only."

I forgot to mention that the sound was only occurring in the left speaker / left channel. If I remove the fluendo mp3 package, what will be used in place of it for gstreamer mp3 playback?
