[MPlayer-dev-eng] Synchronization of players in LAN

[J.A. Gutierrez]

	Hello

	I'm trying to synchronise several players running on several
	computers connected to a dedicated 10/100 Ethernet switch. Each
	one reads a different movie (video only) from its internal hard
	disk, and resolution will be 768x576.

	I'm thinking of a simple solution:

	- Add some code at mplayer startup so it will wait for an UDP
	broadcast packet (sent by a central master in the LAN). This
	way all the players would start at the same time.

	- Use NTP to keep in sync all the computers' clocks, and trust
	mplayer's rtc synchronisation feature.


	With this simple setup, could we be sure all the players would
	keep the synchronisation? Or should the master computer track
	them all and take control on their speeds?
	How difficult would be to add code so all the player synchronise
	using the LAN? Or should I use some external clock connected to
	all serial ports? Or use a totally different approach?


	Thanks.
