[ubuntu-mono] [Bug 935762] [NEW] Gapless playback doesn't work

Public bug reported:

In Ubuntu 11.10, Banshee doesn't support gapless playback very well. It
has an option in the preferences that claims to enable the feature, but
it simply doesn't.

With AAC and MP3, this is due to a format limitation. In those formats,
the frame length is fixed, and so the last frame has some silence at the
end, causing a slight gap. Several encoders, like LAME and Nero AAC,
have implemented a tag that stores the correct track length in
milliseconds. However, Banshee ignores this metadata, introducing the
small gap at the end of each track.

With FLAC, this shouldn't be an issue. However, there's an even larger
and more noticeable gap between FLAC songs.

Steps to reproduce:
1. Cue two or more gapless songs, such as those on side B of Abbey Road by The Beatles.
2. Play both songs in the correct order.
3. Observe the gap.

This bug was already marked as fixed in this Launchpad around 2006, but
it's clearly not.
