RTSPUrl.decodePathComponents

Splits the path of url on '/' boundaries, decoding the resulting components,

The decoding performed by this routine is "URI decoding", as defined in RFC 3986, commonly known as percent-decoding. For example, a string "foo\2fbar" will decode to "foo/bar" -- the \2f being replaced by the corresponding byte with hex value 0x2f. Note that there is no guarantee that the resulting byte sequence is valid in any given encoding. As a special case, \00 is not unescaped to NUL, as that would prematurely terminate the string.

Also note that since paths usually start with a slash, the first component will usually be the empty string.
