[MPlayer-users] Synchronizing multiple instance of Mplayer over the network

[Lehni]

I imagined something along these lines, but did not know mplayer  
enough to know where to start looking. Thanks a lot for the pointers!

And it seems that time and position can be retrieved:

http://howto.wikia.com/wiki/Howto_configure_MPlayer/input-cmdlist

get_percent_pos
get_time_pos
get_time_length

So using these commands and speed_incr, I think I should be able to  
make the players follow a centralised clock pretty exactly.

Very nice!

Thanks,

Lehni
