| dvd_reader_t* DVDOpen | ( | const char * | ) |
Opens a block device of a DVD-ROM file, or an image file, or a directory name for a mounted DVD or HD copy of a DVD.
If the given file is a block device, or is the mountpoint for a block device, then that device is used for CSS authentication using libdvdcss. If no device is available, then no CSS authentication is performed, and we hope that the image is decrypted.
If the path given is a directory, then the files in that directory may be in any one of these formats:
path/VIDEO_TS/VTS_01_1.VOB path/video_ts/vts_01_1.vob path/VTS_01_1.VOB path/vts_01_1.vob

Reads block_count number of blocks from the file at the given block offset.
Returns number of blocks read on success, -1 on error. This call is only for reading VOB data, and should not be used when reading the IFO files. When reading from an encrypted drive, blocks are decrypted using libdvdcss where required.

Get a unique 128 bit disc ID.
This is the MD5 sum of VIDEO_TS.IFO and the VTS_0?_0.IFO files in title order (those that exist). If you need a 'text' representation of the id, print it as a hexadecimal number, using lowercase letters, discid[0] first. I.e. the same format as the command-line 'md5sum' program uses.
