In all cases, the preview window on the server (the Raspberry Pi) can be suppressed with the `-n` (`--nopreview`) option. Note also the use of the `--inline` option which forces the stream header information to be included with every I (intra) frame. This is important so that a client can correctly understand the stream if it missed the very beginning.

NOTE: Recent versions of VLC seem to have problems with playback of H.264 streams. We recommend using `ffplay` for playback using the above commands until these issues have been resolved.
