Just a quick note to say that the DSP task encodes the test .au file
correctly. Still a minor ;) issue that the DSP crashes after the DSP
has finished the encoding task (I think this is probably due to a

Hi Chaps,
I have been thinking more about this and I think another approach
could be considered.
It would be easier to plug your work into everything else if you wrote
it up as a patch to the regular sbc.c so it transparently chooses the
soft or dsp codec at runtime. It would work with the
I only say stepping around gstreamer since the gst way would be to
make one gst plugin for soft and one for dsp codec and let gst choose
one when building a pipeline. ie, they're prepared for multiple
implementations of a given codec.
Ah, ok, I'm with you now.
Well as you said before,
It would be easier to plug your work into everything else if you wrote
it up as a patch to the regular sbc.c so it transparently chooses the

I've re-written the original thread-based (async) code today and it's
now synchronous - a call is made to sbc_encode() on the ARM and it's
passed through to the DSP and the work is done and the data passed back.
This should all fit in without any changes to the code which calls the
