HDSync provides synchronous playback of different HD videos on multiple screens. For video art, video wall, and dome installations, it provides realtime synchronized playback of audio and video, allowing consumer-grade HD decoders to synchronize playback using multiple devices connected via the local network.

Recent releases


Release Notes: An irregularly occurring freeze on long term playback was fixed by adding the optional dependency to FFMpeg, now used to detect the movie length. Documentation is updated.


Release Notes: This release fixes the "static" network configuration to let nodes handshake on a local network without the need for a DHCP server.


Release Notes: This release consists of a full rewrite of HDSync in C/C++, eliminating most of the shell scripted interaction, making it more portable, and condensing operations into a single process for a lower latency. The freeze occurring after 4 hours looping is now fixed, along with a better network handshake mechanism using TCP broadcast (PGM) via the ZeroMQ library. Sync precision is also improved, but for a smooth loop transition video files need to have added 5 seconds of black at the beginning. This is the last release that will get development support by NIMk.nl.


Release Notes: This release improves hdsync stability by implementing a parallel watchdog process, fixing a freezing bug that occurred after playback for a long time. It also enhances logging, adds an option for manual network configuration, and increases the accuracy of sleep timing adjustment to micro-seconds.


Release Notes: This release improves overall stability and performance, makes the network handshake more robust, and fixes looping of videos. The project documentation was updated, and there is also a new Web site and a mailing list.

Hi jaromil,
thanks for your work, but source package for release 0.6.1 is not downloadable

Hey guys
Fantastic work - I've used your older versions of the software for some time. I've tried this newer version out and love it! Although I've found that pretty consistently it refuses to continue sync after 6 or so hours. It'll lock up on the last frame of the video and sit there doing nothing. It appears as if the scripts are still running under the hood, but the video locks up. Where do I submit bug reports on Freshmeat? Do you have any pointers? I've tried all the different versions of the 1.02.21 series firmware.
