The digital video syncstarter software is developed to provide synced playback of multiple videos on multiple screens.
In the video art field there are many artworks requiring the real-time synced playback of audio/video: HDSync provides such a functionality for HD decoders, to sync HD video playback on multiple devices.
A stable version of HDSync sourcecode is out: 1.2 codename "Time Based Arts" comes complete with sourcecode and a ready to use app.bin.
If you are wondering why the hell one would sync the playback of multiple WDTV boxes, have a look at this Video Wall Project by Jeff Campbell which succesfully used the WDLXTV firmware and this HDSync app to run his 37 channel (THIRTY-SEVEN!) video wall. Cheers Jeff!
This release consists in a full rewrite of HDSync in C/C++ that eliminates most of the shell scripts, 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 black at beginning.
This is the very last release that will get development support by NIMk.nl.
