Perl operators question

Here's a real beginners question: What do the assignment operators "||=" and "&&="do? I understand "+=" and "-=" and the like;, but I can't figure out what these two do. Perldoc perlop isn't much help, saying only that they "work as in C", and my copy of "The C Programming Language" -- don't ask

I'm looking for a Perl module that, when given a Quicktime MOV file, will calculate the dimensions of the movie. I've found modules that'll find the dimensions for certain still image formats (Image::Info and Image::Size, as well as PerlMagick), and MPEG files, but not Quicktime MOV files. Anyon
