Copies the existing Bluray protocol format to add DVD protocol support
using
libdvdnav. Since title selection is mandatory ffprobe cant provide
information
for the complete disk but a single title only. Chapter information for
probe
will also be missing. To see a complete disk catalog of
titles/chapters the
tools/dvd2concat perl script should be used.
