We should have it play one of the wav files instead of an mp3

[Nicholas Skaggs (nskaggs)]

It's fair enough to play an mp3 file as a test, but that is testing format support a bit more. I would suggest creating a test specifically for testing whatever formats we want to support. Remember to include the needed dependencies when this happens (which I believe is the issue here)

For fixing this specifically, add another ogg file instead (re-encode the same file if needed :-) )

[Andrew Hayzen (ahayzen)]

Do you know which package we have to depend/recommend on to support MP3 and other 'restricted' formats?

I guess something like gstreamer1.0-plugins-ugly? or is there a specific qt package?

Thanks,

Andrew

[Paul Larson (pwlars)]

I don't suggest depending on having that installed. We're looking at converting over to pulling the click package and the tests would then have to come from bzr - which means no dependencies can be detected. Especially in the case of system images, even if we knew about the dependency, installing extra packages would not be possible due to space limitations. Using ogg or wav ought to work instead of mp3 though.

Fix committed into lp:music-app at revision 93, scheduled for release in music-app, milestone Unknown

[David Planella (dpm)]

Just a quick heads up that as of today we've re-gained the ability to play MP3 files out of the box (see bug 1222024).
