 Real time for video usually means at the right rate, something which
is essential if you want to transcode on the fly in a media server. That IME
is the only time there's a hard requirement for transcoding speed.

 Yes this is true - I did not invent the terminology. However real
time processing has always meant getting the job done within a specified
time interval or by a specified time. Payroll is a real time application for
example (if it's not finished by payday there will be loud complaints).

 However my point remains that you can transcode perfectly well with
modest CPU if you aren't fussy about how long it takes.
