libquvi 0.4 doesn't allow us listing the formats supported by a streaming site without doing additional network accesses, so switching formats was not supported with it. (It's different with libquvi 0.9.) But the most important case is switching between SD and HD. Usually, --quvi-format=default will get SD, while --quvi-format=best gives HD. Use this, and pretend that an URL supported by libquvi 0.4 supports both of these. "cycle quvi-format" will switch between these. If the user specifies something else via --quvi-format, this is included in the list of switchable formats additionally to "default" and "best".
