Hi:

With regard to multiple streams, yes you can use streamtranscoder, but you
can also do it in ices (provide multiple ogg streams, that is).  Here's an
excerpt from the config I maintain to show how it's done.

                <instance>
                        <hostname>linux-speakup.org</hostname>
                        <port>9000</port>
                        <password>********</password>
                        <mount>/egoplay.ogg</mount>
            <yp>1</yp>   <!-- allow stream to be advertised on YP, default
0 -->

                        <reconnectdelay>2</reconnectdelay>
                        <reconnectattempts>5</reconnectattempts>

                        <maxqueuelength>80</maxqueuelength>

                        <!--
            <savefile>streamdump.ogg</savefile>
             -->
                </instance>

                <instance>
                        <hostname>linux-speakup.org</hostname>
                        <port>9000</port>
                        <password>********</password>
                        <mount>/egoplay64.ogg</mount>
            <yp>1</yp>   <!-- allow stream to be advertised on YP, default
0 -->

                        <encode>
                                <quality>0</quality>
                                <samplerate>44100</samplerate>
                                <channels>2</channels>
                        </encode>
                </instance>

                <instance>
                        <hostname>linux-speakup.org</hostname>
                        <port>9000</port>
                        <password>********</password>
                        <mount>/egoplay24.ogg</mount>
            <yp>1</yp>   <!-- allow stream to be advertised on YP, default
0 -->

            <!-- stereo->mono downmixing, enabled by setting this to 1 -->
            <downmix>1</downmix>

            <resample>
                <in-rate>44100</in-rate>
                <out-rate>22050</out-rate>
            </resample>

                        <encode>
                                <quality>-1</quality>
                                <samplerate>22050</samplerate>
                                <channels>1</channels>
                        </encode>
                </instance>

A couple of things to note here.  The first instance just sends out the
data as it is.   If you're inputing from a soundcard, you can't have an
entry that looks like this - you have to encode.

In the last section, you'll notice the downmix, resample and encode
sections.  I've put them in this order for clarity.  It doesn't matter
which order these sections are in, as long as they're all present.

Hope this helps.

Geoff.
