Synchronize multiple vlc players

[zozizozu]

Hi,
I'm trying to synchronize multiple vlc players that are reading different streams :
I have one vlm broadcaster that generate multiple http streams, then many players that are reading it.
The goal is that all players read the frame N at the same time.

I've search about this but vlc+synchro gives a lot of results, and i did not found any interesting things ( except CAVE-MPlayer : http://persephone.cps.unizar.es/~spd/cmplayer/ , but i'm using vlc because i need this to work on linux + mac + windows )

On the broadcaster side, i'm considering streams are synchronized ( i plan to run a telnet thread that will check streams position and seek some ms if needed ).

So, i've first try to start players using "vlc http://host:port/SomeBackground --input-slave=http://host:port/TheStreamIwant --extraintf=netsync --netsync-master " but it does not make the trick.

I also think about using the mosaic module, making a single stream with all i need, then players can all read the same stream ( cropping the image ), and use the netsync module. It should work but i need some big definition for each players, if i have 20 streams that are 1920/1080 , that's a so big size to stream ...

Now i don't know what or where to search, as you see, any advise, suggestions or ideas are very welcome.

Thanks for your time

netsync will work only with the same movie on the different machines.
