Hello,

I want to use libVLC and synchronize multiple instances. Currently I use libvlc_media_player_set_time(), but the seek takes different amounts of time, so I never get a good sync result. I don't want to use the netsync plugin but provide the functionality my own. I still saw that netsync uses input_ModifyPcrSystem(). I think that way it is able to avoid the problem with the delay. So I thought if libVLC would expose an interface to that method, I could use it to sync on a basis of milliseconds. Is it right that input_ModifyPcrSystem() takes the number of millisecond since the beginning of the media?
Since I synchronize on a timestamp (time when media would have been started from beginning for current position), I would want to use the absolute parameter.
Please correct me if any of my assumptions are wrong.

If the implementation is as easy as described, I would be able to do it, although I would have to setup a build environment. So I want to ask the developers to implement that if it's not taking too much time (and they believe it would be of common use ).

Did you look at syncplay.pl ?

syncplay shows the same behaviour. I want to have a synchronization similar to netsync e.g. to be able to make a wall. When I play HD videos, they often need different times to load/buffer. So when I seek to a time, the playback gets already out of sync while seeking. I thought that netsync avoids that problem by using that method. Am I right that it only works for small changes?

Possibly, yes.

@liIngo did you succeed with synchronization ?
