Cannot decode

[juacompe]

I tried to use amf3:decode to decode AMF content which I have captured in a file named /tmp/tsung_recorder20130311-1025-10.bin. However, it seems to me that the result is not decoded.

Below is what I captured from my erl shell.

juacompe@horus:~/projects/herffjones/erlang-amf/src$ erl

I also tried similar approach in Python using pyamf library.

juacompe@horus:~/projects/herffjones/tsung_recorder/tsung_recorder20130311-1025$ ipython 
Python 2.7.3 (default, Aug  1 2012, 05:14:39)

In [1]: from pyamf import remoting

In [2]: content = file('/tmp/tsung_recorder20130311-1025-10.bin','rb')

In [3]: envelope = remoting.decode(content)

In [4]: print envelope

The binary I used in my repro steps can be downloaded at tsung_recorder20130311-1025-10.bin.

Any comments or suggestions would be highly appreciated.
