Perfect.
For other readers of the thread - QNAP is behaving as a mixed endian

The output of a code pasted below is as follows on different ARM

but swap the first and second 32 bits in the binary representation of

Correct about swappign 1st and 2nd word when 32 bit number however I
think your version of RTMP.pm won't work for 2 reasons.
