Once installed, miro can be configured to use xine OR gstreamer as backend ... but we have xine-lib listed as dependency, wouldn't it be better to have it listed as suggestion instead of forcing users to install xine-lib (and few others) as dependency even if not used?

Additional info:
* package version(s) - 2.5.4-2
This task depends upon

Reason for closing:  Not a bug
Additional comments about closing:  Not a bug anymore: miro has been updated to 3.0, there's no xine backend there anymore.

no I don't think it makes sense because optdepends is for additional functionality, not for core functionality which IMO playback really is. Either way if I'm not mistaken the xine backend will be removed from miro when subtitle support lands (probably in 2.6) so in the future there will be a dependency on gstreamer if that happens.

I agree with you that playback is a core functionality, but gstreamer delivers it and in fact the package depends on gstreamer0.10-good too ... so what's the point of having two different backends listed as dependecy if you only need one?

The minimal gstreamer dependencies were added for  FS#14684  , not sure if it is still the case but I presume it is as it is just one minor release ago.
Comment by Giulio Fidente (giulivo) - Monday, 01 February 2010, 22:49 GMT
It is still the case, gstreamer is currently the default backend for miro and now we correctly have it included in the dependencies; that's why I'm asking why we need xine-lib too.

As per  FS#14684  you had gstreamer in the optional packages, while it is the default, I'm just wondering why we don't move xine-lib in the optionals, considering that it is not needed to run miro (nor to have playback functionalities that gstreamer delivers)
Comment by Ronald van Haren (pressh) - Monday, 01 February 2010, 22:58 GMT
The listed gstreamer deps are not enough to have playback, it needs some more codecs. Initially the xine backend was chosen because of instability of the gstreamer one, and because of the smaller total size of depencies. This may have changed, I don't know. Could you back it up in numbers for a minimal wm?

On a clean installation, without X, xine-lib only asks for 51 dependencies.

gstreamer0.10-good-plugins 97
+ gstreamer0.10-ugly-plugins 108
+ gstreamer0.10-bad-plugins 150

In terms of dependencies, xine-lib is more feasible than the gst framework ... but Miro depends on GNOME, which in turns would install a lot of those gstreamer dependencies; unfortunately I don't have any clean GNOME installation to check how much those numbers would change, I'm just assuming that a GNOME user will probably have gstreamer0.10-good-plugins already installed, but this is just _my_ (and possibly wrong) assumption.

The last option which would avoid to people using gstreamer to install xine-lib (and its dependencies) is to have them both listed as optionals but that would break somewhat a "core functionality", unless the user choose and install manually one or another backend.

I would still personally prefer to have gstreamer plugins in by default and xine-lib as opt, but at this point that's only my opinion.

Thanks for listening anyway.

as from official Deps page:
and xine-lib OR xine-ui is not listed
