Hello Alastair :-)
By default, anything downloaded by rtmpdump
ends up inside the Adobe FLV container,
with ".flv" as file extension!

Again, this is reported by rtmpdump
("INFO: sampletype mp4a", you should also see:
"INFO: audiocodecid mp4a") and this info
refers to the elementary audio stream inside
the FLV container.

".m4a" is the file extension of MP4 files
containing only an audio stream inside the
MP4 container; is that what you really
want to do (i.e. extract only the audio from
the FLV file and put in within the MP4 container)?
My guess is that you'd rather
LOSSLESSLY REMUX the FLV file to
an MP4 file, keeping both video+audio streams...
Use ffmpeg to perform the remux:
ffmpeg -i foo.flv -c copy -bsf:a aac_adtstoasc foo.mp4

Pardon me, but I do not quite understand
what you're saying here - my command
above does a lossless remux without transcoding -
TRANSCODING is not what you'd want
because it is a source (and time) demanding
procedure - resort to transcoding in the event
your hardware media player does not support
the H.264 AVC video codec (very unlikely...)
