Shellcheck flags both the "read" and the "ffmpeg", with messages to the
effect that ffmpeg might swallow up stdin - not realizing that the -u3
means the "read" is not reading from stdin.

Maybe the shellcheck code does know about -u, but simply doesn't
recognize it when it is clumped like that, together with another
option and its own argument.
