The playpath is what needs to have the query parameters.

rtmpdump -r "rtmp://s21hgu5r2yq4zz.cloudfront.net/cfx/st/mp4:webinars/how-to-trade-a-small-account-and-turn-it-into-a-big-one.mp4"
-a cfx/st -y "mp4:webinars/how-to-trade-a-small-account-and-turn-it-into-a-big-one.mp4?Expires=1234&Signature=abc&Key-Pair-Id=def"
-o how-to-trade-a-small-account-and-turn-it-into-a-big-one.f4v

It is also advised that you use the most-current version of rtmpdump, not v2.3.
