This might be useful to some of you trying to move files out of MythTV via
mencoder or the like and wishing for a sane/useful output name.
It's nasty hack and slash of the myth.rebuilddatabase.pl, given a filename
it returns the Title and optionally the Subtitle with a couple of options.
getshowname.pl 1059_20030401220000_20030401220000 --replace=. -s -sublen=16
would return something like:
A.Great.Show:This.Episode.is
Where A Great Show is the title, (--replace=.) replaces spaces with . (any
sting can be used here) and the subtitle (-s) is after the : with it's
length truncated at 16 (--sublen=16) characters.
Caveats: Tons of them; first thing that comes to mind is that it doesn't
sanatize the filename for Windows, all sorts of illegal filenames could be
generated.
