     Set the size of the cache in kilobytes, disable it with ``no``, or
     automatically enable it if needed with ``auto`` (default: ``auto``).
     With ``auto``, the cache will usually be enabled for network streams,

     May be useful when playing files from slow media, but can also have
     negative effects, especially with file formats that require a lot of
