Software implementation of SliMP3

[Paul Warren]

Are there any software implementations of the SliMP3 protocol? I'm
aware of triplefat, but I'm looking for something that does the audio
rather than the UI.

I currently use mpg123 pointed at stream.mp3, but there are limitations
with this (slow response, mp123 getting upset and dieing).

I might have a go at implementing this myself, but wanted to check that
it hasn't already been done.

Can someone point me to the protocol docs? They don't appear to be
under cvs/docs, as the website suggests.

look in your slimserver's help section, under technical information.

I hate to have to point this out, but:

| Note: This document describes the previous version of the SLIMP3 protocol.
| This document will be updated to accurately reflect the current protocol. It
| also doesn't describe the Squeezebox control protocol. Sorry.

Looks like we have to wait a bit.

aye. docs are a hard thing to keep up.
if you are familiar with Perl, try having a gander at Networking/Protocol.pm
it can at least get you started as to what has changed since the help docs were
written.

sorry

Well, I guess that's the beauty of Open Source - it's documented in the
source if nowhere else. Perhaps someone could give me a few pointers...

- The old protocol was UDP. The new one uses TCP, correct?

- Which version of the server implemented this change?

- The squeezebox has its own protocol? What does that do?

thanks,

Paul

The Squeezebox and SLIMP3 protocols are very different. To look at the
source, the SLIMP3 stuff is implemented in:

Slim::Networking::Stream
Slim::Networking::Protocol
Slim::Player::Slim

and the Squeezebox stuff is in:

Slim::Networking::SlimProto
Slim::Player::Squeezebox

Of course there's a lot of help from the other modules, but that's the
core.

Slimp3 uses UDP and still does
Squeezebox uses TCP (slimproto.pm)

SlimServer 5.0 is the start of the TCP support. I'm not sure which specific
version of Slimp3 Server made the larger changes in the UDP protocol where the
current docs became obsolete.

streams music to the squeezebox Generally allows more useful bandwidth, less
overhead and some room to grow its uses in the future.

Hey Dean,

Obviously the SqueezeBox is the new direction for SlimDevices but I'm curious
about future SW support for the legacy Slimp3 player. Will SlimDevices
continue to test against this HW platform? If so, any plans to discontinue
support in the future?

We intend to fully support SLIMP3.
