Merge lp:~laney/unity-lens-music/gstreamer1.0 into lp:unity-lens-music

[Iain Lane]

Port from gstreamer 0.10 to gstreamer 1.0

For Raring, we want to port everything in main from gstreamer-0.10 to gstreamer-1.0.

unity-lens-music is on that list. This branch implements the port.

I'm sure there are still gremlins ("soft" 0.10/1.0 changes) that will need to be ironed out, but in my testing this performed as well before the port as after. (That is, not spectacularly - previews still frequently fail to play - but it at least works).

[Iain Lane (laney)]

BTW if you want to test you should manually install gstreamer1.0-{pulseaudio,alsa} and the plugins they need, otherwise you won't get any sound. :-)

[Didier Roche-Tolomelli (didrocks)]

Please, do not merge until Laney gives the green light, meaning gstreamer 1.0 in main :)

[Michael Terry (mterry)]

Looks fine to me, and it does seem to work as well in my quick testing (it only uses it for preview mode music playing, right?).

review: Approve

[Michael Terry (mterry)]

Oh wait. Is there not a bug for this? Can you open one and link it please before it gets approved for a proper debian/changelog entry?

[Michael Terry (mterry)]

Laney is on holiday, whoops. I went ahead and made a bug and linked it. Approving.

review: Needs Fixing (continuous-integration)

[Michael Terry (mterry)]

To resolve the merge conflict, since laney is on vacation, I made: https://code.launchpad.net/~mterry/unity-lens-music/gst1/+merge/139031

So I'll mark this branch as rejected.
