Full support for DVD-Audio (including decryption of CPPM)

Postby kurkosdr » 22 Mar 2010 20:14

Hi there.

First of all, I want to say I am glad to see VLC 1.1 making steady progress. You guys are full of nice surprises.

Also, it's was nice to see that it will play .AOB files. Support for DVD-Audio was the last step to achieve full compatibility with DVD media, thus making software like WinDVD unnecessary for people without a Bluray drive.

One thing only: Why stop on AOB files, and not include decryption for the CPPM copy protection DVD-Audio discs use?

Open source code for bypassing CPPM has been around for a while (on software like SHAPlay etc) so why not integrate it to VLC?

If it could be done with libdvdcss, it can be done with libdvdcxpm.

Simple: noone had the time to do it.

Laurent had time for .aob extension (was not that difficult) but didn't had time for DVD-Audio.
Patches are VERY welcome on this, and we can pay a student through Google Summer of Code for that. But don't expect anything from the core team.

Glad to hear this.

At first, I thought there was some legal obstruction that didn't allowed that. Since there is no such thing, I have no problem at all waiting.

Code is welcome. Legal will come after that.
