Ah, thanks very much.

I thought I was not being clear.

So in essence either
a) a hand made file: Slice up two seconds of audio - put as header (and any other data you want dumping in there), buffer it, splice in second of video (say), then swap back to audio etc.

or

b) just get a known format and handle it in that way - i.e higher priority to audio consumption.

I like the sound of b) better.

One thought: I will try cramming some dummy "audio" through that demo via loading a wave first and swapping it into the buffer, see what results.

Start there come to think of it. (I asked the thread to be renamed as you suggested, thanks)
