OK, I guess this is a bit too specific for this list, but I'll ask
(once) here anyway...

I have installed the software and rebuilt ffmpeg and it appears to
recognise the sound format but is still not converting it - I think
because I need to select a proper audiocodec for flash video...

I have tried using adpcm_swf as the output audio codec but that
generates an error...

Error while opening codec for output stream #0.1 - maybe incorrect
parameters such as bit_rate, rate, width or height

Any flash gurus know what the proper settings should be?
