Just to bring this to a conclusion, I was referring to the 1.x
series of documentation while using 0.10.x. Referring to the
correct documentation helped me get the interleaving to swap
channels working.<br>

Generally, failure to link is due to caps errors. So, you need
to crank up the logging to see what is not happy, where the link
process fails. The logging during setup can be quite verbose,
but you need to get some things. So, try export GST_DEBUG=*:3,
GST_ELEMENT:5 see what you get and go from there. Please report
your findings a) for additional comment/help if needed, b) as a
guide for others.<br>

I'd like to use gstreamer to play some videos while
directing the audio output to specific channels. My computer
has two sets of stereo outputs (LR & rear LR) and I'd
like to be able to direct which of these receives the output
of playback.<br>
<br>
As far as I understand it, the interleave & deinterleave
plugins should be able to do what I want, so to get my head
around how this could work, I tried the example in the
documentation*:<br>
$ gst-launch filesrc location=file.mp3 ! decodebin !
audioconvert ! "audio/x-raw,channels=2" ! deinterleave
name=d interleave name=i ! audioconvert ! wavenc ! filesink
location=test.wav d.src_0 ! queue ! audioconvert !
i.sink_1 d.src_1 ! queue ! audioconvert ! i.sink_0<br>
<br>
But when I execute this with an mp3 file, I get this output:<br>
<br>

<br>
This is using gstreamer 0.10.<br>
<br>
Could someone enlighten me as to why this doesn't work?<br>
