This is possibly not relevant to everyone here, but might be useful. At the very
least, it has been great for debugging.
I was fixing bugs in my DVD/Bluray playing code, being unhappy about how
complicated it had become. Then it occurred to me the fix I was about to apply
already existed for plain RAR playing code, which calls "unrar" to list and play
media.
So I created a "undvd", which simulates all arguments and output of "unrar", to
list (undvd v ), send to stdout (undvd p) and extract (undvd x).
Now all RAR files, DVD images (iso, img, toast, VIDEO_TS, bluray and /dev/drive)
can use the same function that calls unrar, (and now undvd).
Since my version of libdvdnav has RAR code, it can also handle ISO inside RAR
files. Although, I should note I fixed some bugs in the opendir/readdir code.
If undvd is compiled without the UDF2.50/bluray code, it can be used against the
vanilla libdvdnav library.
Example output:
**** 1 : Bluray ISO
# ./undvd v -d -v -c- -p- -y -cfg- -- movietest-bd5.iso

But yes, it doesn't do anything with DVD Menus, just streams.
