[Pyxine-devel] Pyxine fails unit tests on Debian unstable

[Joe W. <wre...@um...>]

Hi,

As you probably saw, I'm packaging Pyxine for Debian. :) Although it
seems to be working fine, four of the unit tests are failing (both with
Python 2.2 and 2.3). This is Xine 1.0rc2, Pyxine 0.1alpha2.

(This isn't the order I get them in, just the order I feel like
commenting on them in.)

Should this be doing >=3D "1-beta4" rather than !=3D? I know string
comparison works for Python versions (and works in this case for Xine's
version), but I don't know if it will consistently work for Xine. Either
way, 1-rc2 does seem to work.

Setting the volume to 25 seems to be setting it to 23 (consistently).
Maybe my sound card / driver precision (SB Audigy) is just too low to
reach 25 accurately? If this is the case, the test should probably be
something like 20 < x < 30.

No idea. Is there some reason why the priority of mpeg2 should be 6,
rather than 0?

Again, I'm not familiar enough with libxine yet to comment on this. If
browsable_ids holds the kind of "MRLs" that Xine is capable of playing,
this is wrong; I can play files just fine.
