Video Synchronization

General advices

  • Make sure videos you want to sync all have equal length and the same codec.
  • Disable features like "CPU SpeedStep" that adapt the speed of the CPU. The videosync algorithm uses the high resolution performance counter of your cpu to calculate timing. This can become unreliable when the bios changes the cpu speed to save power or performance.
  • Syncing does not seem to work for audio. Needs more investigation...

 FileStream (DShow9 Boygroup)

With Boygrouping
In a boygroup simply use the  FileStream (DShow9 Boygroup) instead of the usual filestream node and boygroup it. Note: multi server boygrouping is not supported.

Without Boygrouping
The  FileStream (DShow9 Boygroup) can also be used in non-boygrouped setups:

  1. on the 'server' machine define the Port.
  2. on every 'client' set the Is Client (hidden pin) to 1, set the Port and the Server IP (hidden pins) of the server. Done.

Examples in your vvvv\girlpower\ directory:

 FileStream (DShow9 Local Master)
 FileStream (DShow9 Local Slave)

To sync videos locally (be it in one or multiple instances of vvvv) just place a FileStream (DShow9 Local Master), define its Master Port and place as many FileStream (DShow9 Local Slave) as you wish.

There can only be one master sitting on one particular port. The slaves listening to this master need to have the same 'Master Port' defined.

If the master node turns red its Master Port is probably already in use.
