Syncplay can synchronize video playback on many players, including Mplayer, MPV, Media Player Classic, and VLC, so that you can watch movies with friends at the same time.
Syncplay synchronizes the position and play-state of multiple media players so that the viewers can watch the same thing simultaneously. This means that when one person pauses/unpauses playback or seeks (jumps position) within their media player, this will be replicated across all media players connected to the same server and in the same 'room' (viewing session). When a new person joins, they will also be synchronized.
Syncplay does not use video streaming or file sharing, so each user must copy the media to be played. Syncplay does not synchronize player configuration, audio/subtitle track choice, playback rate, volume, or filters. Furthermore, users must manually choose what file to play as Syncplay does not synchronize, which is open. Finally, Syncplay does not provide a voice or text-based chat platform to allow for discussion during playback. This is because Syncplay is intended to be used in conjunction with third-party communication solutions such as IRC and Mumble.
