Help with this rtmpdump error please

Hey guys!
I am trying to download these videos for my exams from a site, but I keep getting:

Code:

RTMPDump v2.4 GIT-2015-12-14 (Compiled by KSV)

(c) 2010 Andrej Stepanchuk, Howard Chu, The Flvstreamer Team; license: GPL

Connecting ...

INFO: Connected...

ERROR: Closing connection: NetStream.Play.StreamNotFound

Here is the command I tried:

Code:

rtmpdump -v -r "rtmps://53c7c8e287199.streamlock.net/vods3/mp4:amazons3/coursekart/videos/1521/topics/ER Diagrams - Part 1 of 1_qtp.mp4"

 -o "DBMS1.flv"

Here is the page source code:
