come in bunches...)

A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : RealMedia File Format

Filename : draft-heftagaub-rmff-00.txt
Pages : 16
Date : 16-Mar-98
The RealMedia File Format (RMFF) is designed to be a generic container
for streaming media data. This data may then be played back locally or
streamed over a network using protocols such as RTSP and RTP. The
format is data-independent, allowing any data type to be recorded,
manipulated and played back.
Note: This document is intended to be informational in nature of what
the file format in use by RealNetworks' RealServer and RealPlayer
implementations. Though we think that there are a lot of important
concepts embodied in this specification, and that it may even make the
basis of a ''standard'' file format, this is intended to eventually end
up as an Informational RFC.
Internet-Drafts are available by anonymous FTP. Login with the username

type "cd internet-drafts" and then
"get draft-heftagaub-rmff-00.txt".

Internet-Drafts are also available by mail.
Send a message to: mailserv@ietf.org. In the body type:
"FILE /internet-drafts/draft-heftagaub-rmff-00.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.

So it's not possible to write a RealMedia player based on this
specification, because it's
"data-independent", i.e. they don't give you the codecs which translate the
bits being encapsulated into sound data.
Or an I reading this wrong?
So let's see, we have
Ethernet
IP
TCP
RTSP/RTP
RMFF
*the actual bits*
I.e. 5 layers of encapsulation. Ace. We should tunnel this over Appletalk
just for kicks.
