The "keep it simple" principle applies-

Unless disk space is a big issue and you need the output immediately after 
recording, use a temp file for this and convert after the download* 
completes (as driven by your script). It'll be much easier all around and 
more tolerant of errors. If you choose to re-encode while downloading, you 
can run into the problem that the re-encoder catches up to the download and 
ends (the circular buffer problem).

*if saving in the downloaded codec, there's no added conversion overhead or 
quality loss.
