recent libdvdcss2 update broke DVD-Support

[AllesMeins]

Since the recent update to libdvdcss2 (1.2.11), I'm no longer able to watch DVD-Movies. Xine fails with:

VLC does pretty much the same i tried it with several diffrent DVDs... So I downloaded and installed an older Version (1.2.10) from http://download.videolan.org/libdvdcss/1.2.10/deb/libdvdcss2_1.2.10-1_amd64.deb and everything was working again. So it seems, something is wrong with the new version

I can confirm the same problem with the latest version of libdvdcss2, and get the 'error cracking CSS key' error.
As I regularly do upgrades on my system, it has become cumbersome having to keep downgrading my version of libdvdcss2 in order to watch my DVD's after every update (uninstall libdvdcss2, then install the older version via the DEB package over and over)

I've done a temporary workaround by extracting the module file "libdvdcss.so.2.1.0" from the archive http://download.videolan.org/libdvdcss/1.2.10/deb/libdvdcss2_1.2.10-1_amd64.deb and copied it over the top of the broken "libdvdcss.so.2.1.0" in /usr/lib . This has allowed me to trick Ubuntu into thinking I have the latest libdvdcss2 installed, and it no longer gets replaced each time I upgrade anymore with apt-get, and I can watch my DVD's in peace.
Hopefully Medibuntu will do a new update with a new version number to fix this issue properly soon.

Hi,

I couldn't reproduce the problem here. Could you remove ~/.dvdcss and try again to see if it helps?

Thanks.

[AllesMeins (spam-startrekarchiv)]

No, unfortunatly removing ~/.dvdcss does not change anything...

I'm affected by this as well with the 1.2.11 version. Reverting to 1.2.10 works. Web searches are not revealing much on this issue, maybe it's a hardware specific problem? With 1.2.11 and a commercial DVD in the drive I would get output like this:

$ lsdvd /dev/dvd5
libdvdread: Using libdvdcss version 1.2.11 for DVD access
libdvdread: Can't seek to block 2655603
libdvdread: Can't seek to block 2655603
libdvdread: Invalid IFO for title 2 (VTS_02_0.IFO).
Can't open ifo 2!

It seems the block that it always stops at is the layer break because I could playback the DVD using mplayer or VLC but only up to the layer break. Using VLC I would get output like this for most of the vobs:

I've just uploaded a new version of libdvdcss. It fixes a regression related to some hardware. Could you test it? Thanks.

I just tried 1.2.12 on a dual-layer commercial dvd with CSS and it's back to working again. Thanks.
