[gst-devel] Convert WMA stream to AAC/MP4 RTP stream

[Chris Burns]

Hi all,
 
I'm trying to setup a gstreamer pipeline to convert a WMA (radio) stream
to an AAC/MP4 RTP stream, to bounce off a DarwinStreamingServer to a
mobile phone.
 
I have purchased, downloaded and installed the Fluendo Windows Media
codec pack for gstreamer
(fluendo-codecs-windowsmedia-bundle-8-3.fedora.i386.rpm) onto an FC11
dev box, but while I can get the WMA stream and save it to disk, I can't
quite get the conversion to AAC and sending via RTP quite right.
 
Can anyone help me a little with this gst-launch pipeline please?
