* aout_SpdifThread: audio output thread that sends raw spdif data
* to an external decoder
* This output thread is quite specific as it can only handle one fifo.
* Now fifo #0 is hardcoded, but when the output is launched by the decoder,
* we'll be able to associate the related fifo to this output.
* Note: all this is wrong: spdif can demux up to 8 ac3 streams, and can
* even take care of time stamps (cf ac3 spec).
