[PD] using pd with mplayer udp sync

[Hans-Christoph Steiner]

Hey all,

Briefly back in Pd for a little bit, we're doing a minor overhaul of Terre Natale: EXIT (http://at.or.at/hans/terrenatale).  I just found out an awesome new feature in mplayer (ok, maybe not so new;):   The UDP master/slave sync mode.  Its really easy to use either as master or slave with Pd. For mplayer as master:

  mplayer -udp-master mycoolvideo.mp4

Then receive UDP on port 23867.  For mplayer as slave:

  mplayer -udp-slave mycoolvideo.mp4

Then send UDP on port 23867.  Here are my patches:

The only data to send/receive is the frame to play, in units of seconds.  So with a 30fps video, the data stream looks like this:
