Let's start with some basics the DVD has a specific file system with some additional obfuscation/crypto That part is usually managed by libdvdread or libdvdnav, they sort out what's in the disk, decrypt it using libdecss and provide the streams. Then it comes to the player/application present you the options and eventually they come to libav for decoding or remuxing. > Now assume that I know my way around code. Where should I start looking?

Are there any bare test tools that I can use as a starting point? I'm thinking libdvdnav is where you should look at, since vlc sort of work the best bet is join #videolan on irc and ask questions there. I hope it helps a bit. lu _______________________________________________ libav-tools mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-tools
