It saves the video as RAW DV, which I think is stereo @ 16 bit, 48 KHz.
However, since we're using a mono radio mic, when we're streaming we're
downmixing to mono, and when we're encoding to x264 we're doing probably
joint stereo (or mono again).

Cool. Thanks.

Well, perhaps I'll drag the kit along to the workshop on the 22nd?

I think so. We didn't get it working properly; dvswitch needs to start
with the "-t" flag to print the tally information, and then we need to
write a second script to capture that (form STDIN) and open and close
the serial port accordingly).
