How to Sync Different Video Files Recorded with NTP

[jay1100]

I searched the forums and I came across some sync options/software (like netsync and syncplay) but they seem to be mostly aimed at synching the same file on multiple players.

I'm building an application that views and records four AV streams from four cameras using nVLC (in c#.Net). The playback streams themselves are designed using the traditional VLC command lines. I'm using a laptop connected to a switch and four IP cameras are connected to this switch and the IP cameras are streaming H.264 video over RTSP. The laptop has an NTP server software on it and this keeps the cameras synched with the laptop. My problem is that I don't know how to sync the videos on playback so that they're playing the same scene (from different angles) at the same time. Is there a way similar to how VLC syncs the audio and video of one RTSP stream that I can use to sync the videos of two or more (AV file playback) streams together (perhaps to one master video?). Sorry if I missed anything obvious, I've been researching this for a few weeks.

netsync might work, if all dts are alligned.

I came across this post while further researching your comment and it looks very promising:

netsync on one pc, does it work ?:
