Okay, good.  So the regular expression is fine.

Probably there was other junk in the input buffer when the
quit command was sent, so VLC saw something like this:

   get_length\nget_time\nget_time\n[...]quit\r\n

Maybe it treated that whole thing as one line and in
response did nothing but print some kind of error message.

   The command `get_length\nget_time[...]quit' is undefined.

Something like that.

You should try inserting carriage returns before the
terminating line feeds of all the other commands, too.
