[Rock-dev] how to customize the synchronization of log replay

[Alexander Duda]

Hi Jakob

To use your custom code block to synchronize the log replay you can do
the following.

require 'vizkit'

log = Orocos::Log::Replay.open('camera_new.0.log')
log.time_sync do |current_time,actual_time_delta,required_time_delta|
  # this is called before each sample is replayed
  # for example:
  wait = required_time_delta-actual_time_delta
  puts wait
  wait  # must return the number of seconds log replay shall wait until
        # this block is recalled. If return value < 0.001 the current 
	# sample is replayed
end

Vizkit.control log
Vizkit.exec

PS:
I extended log_control a little bit. You can now see which streams are
replayed. If you click on one of them a new window will open which
displays the content of the stream. At the moment there is only a
plug-in for frames all other types are displayed in a tree view. But
feel free to add more plug-ins.
