2.0.1 in tree, its a bit early for stabilising it so i'd like to ask arch teams to be particulary cautious with their tests

Ok, I'd say to wait few days if any user will report anything

note I was including the whole 2.0.x serie in this statement :)

Alexis, that version uses unstable zlib that is not ready to go to stable.

There is a way to force to use our stable zlib?

changed 2.0.1 to allow stable zlib too:

  20 Mar 2012; Alexis Ballier <[e-mail]> vlc-2.0.1.ebuild:
  allow stable zlib too, vlc will build its bundled minizip version with it
  though, bug #408881

bug #409001 isnt a blocker with the current stable ffmpeg, or even stable candidate afaik

i take that back, it seems due to ffmpeg git compatibility code added in 2.0.1 which breaks compatibility with older versions...

[Comment 9 Davide Pesavento 2012-05-02 16:59:31 UTC]

is it ready to go stable now?

[Comment 10 Ben de Groot (RETIRED) 2012-06-12 04:23:39 UTC]

OK'ed by aballier on IRC.

Arches, please go ahead and mark stable =media-video/vlc-2.0.1

amd64 stable, thanks Maurizio.

[Comment 13 Andreas Schürch 2012-06-13 11:52:31 UTC]

x86 stable, thanks.

[Comment 14 Michael Weber (RETIRED) 2012-06-14 21:35:13 UTC]

ppc stable

[Comment 15 Raúl Porcel (RETIRED) 2012-09-11 15:35:12 UTC]

alpha stable, marked -sparc on sparc as it sigbuses, you can remove the old 1.1.3 version when all is done

[Comment 16 Anthony Basile 2012-09-13 11:32:03 UTC]

1) I stabled ppc64

2) I removed vulnerable version: vlc-1.1.13

Note to maintainer:

   media-video/vlc/metadata.xml: unused local USE-description: 'id3tag'
   media-video/vlc/metadata.xml: unused local USE-description: 'stream'
   media-video/vlc/metadata.xml: unused local USE-description: 'remoteosd'
   media-video/vlc/metadata.xml: unused local USE-description: 'libv4l2'
   media-video/vlc/metadata.xml: unused local USE-description: 'libv4l'


3) Its keyworded for ~arm.  Is there any reason we should not stabilize it for arm?  I can do that.

meaning you removed the old version poorly, please fix...
