[FFmpeg-user] How to broadcast a video -- in depth ??

read both audio and video in a buffer, say 1 sec, then you are able to
process audio and video simultaneously, or that quick after another that
no one will be able to see or hear that there is a gap. If there is a
picture shown to you for 0.033333 second you won't be able to tell what
you've seen.
