playback of DRMS protected M4P-files is broken

The playback of DRMS protected M4P-files using FairPlay version 2 bought with iTunes fail to play even on the computer they were purchased on. The console states "mp4 error: drms_init( priv ) failed". After that, the GUI pretends to play the file, but it does not output any audio. (everything on OSX)

Please check whether that still works on Win32/Linux.

changed milestone to %0.8.5-final

changed the description

With which version ? If it's with the trunk, maybe my MD5 changes could have broken something...

If it's on 0.8.2, then forget about it, these changes are only in trunk.

I'm afraid not many people can check this unfortunately :(

It's on 0.8.2 as well as on trunk. Since 0.8.1 does not work either, this seems to be a rather old breakage. Perhaps we can ask jlj to have a look at it.

Yeah, well only jlj can fix it, I'm afraid.

< jlj> courmisch: re. DRMS, getting the userkey(s) doesn't work anymore
       because Apple changed the format, however that doesn't matter if you
       get your key by other means, e.g. FairKeys (downloading keys from Apple
       servers)
< jlj> that is, getting the userkeys from the local key store on the harddrive
       doesn't work anymore

< jlj> courmisch: re ticket 242 - getting the keys from the keystore under
       MacOS X was never supported (the key which is used to encrypt the
       keystore is not generated the same way under MacOS X as on Win32)
< jlj> on Win32 getting the key from the keystore only works if you're using
       an older version of iTunes, because we don't support the key store
       crypto used by recent iTunes versions
< jlj> I haven't bothered to reverse the new key store crypto because FairKeys
       can be used instead and it is cross platform

These days attempting to open an m4p causes VLC to hard crash...maybe it should not register the extension...

backtrace? Sample?

changed milestone to %Bugs paradize

looks like with 2.0.1 it crashes, with with 2.0.2 it doesn't crash, just plays silence (mp4 debug: track[Id 0x1] does not provide Sync Sample Box (stss)) and with 2.1.0 snapshot it doesn't play (mp4 error: cannot create es for track[Id 0x1]). But none of them crash now so that's good.
