Pass create=True if you want this function to generate a

Normally, you should pass create=False. This will only
create a filename when the file already exists from a previous
version of gPodder (where we used md5 filenames). If the file
does not exist (and the filename also does not exist), this
function will return None.
If you pass force_update=True to this function, it will try to
find a new (better) filename and move the current file if this
is the case. This is useful if (during the download) you get
more information about the file, e.g. the mimetype and you want
to include this information in the file name generation process.
If check_only=True is passed to this function, it will never try
to rename the file, even if would be a good idea. Use this if you
only want to check if a file exists.
If "template" is specified, it should be a filename that is to
be used as a template for generating the "real" filename.
The generated filename is stored in the database for future access.
