The main issue here is actually ccextractor's buffering of input.
FILEBUFFERSIZE is defined to be 16MB which, at the script's suggested
bitrate of 4.5Mb/s, takes around 30s to fill. Changing FILEBUFFERSIZE to
something smaller, like 1MB, makes it much more practical for Live TV and
in-progress recordings.
