Re: [Vnc2swf-users] error: unpack str size does not match format

[<lfk...@ya...>]

Well,

I guess I found the bug. I'll let Yusuke fix it! :)
The RFB protocol (http://www.realvnc.com/docs/rfbproto.pdf) states that
first the server sends the maximum protocol version it understands and 
then the client sends the version it wants to use.
Check function "init" in class RFBProxy. It's inverted!  And it assumes that
the handshaked version is the one returned from the server.  It's not. It's the
one sent by the client.
The RealVnc sends version 3.6. So the client must send a 3.3.
The problem is that the client is trying to decode the messages as 3.6, which
is not 3.3 so it ends up in the else clause along with the 3.7 and 3.8.
Just to make it work without much thought:
  def init(self):
    # recv: server protocol version
    self.server_version = self.recv(12)
    # send: client protocol version
    # just force version 3.3 for now
    # but should try the highest between 3.3, 3.7 and 3.8
    self.send('RFB 003.003\x0a')
    self.server_version = 'RFB 003.003\x0a'
    if self.debug:
      print >>stderr, 'server_version: %r' % self.server_version
    return self

That's it!
