clocksync

Simple element that passes all buffers and buffer-lists intact, but synchronising them to the clock before passing.

Synchronisation to the clock is on by default, but can be turned off by setting the 'sync' property to FALSE

Example launch line |[ gst-launch -v -m videotestsrc ! clocksync ! fakesink silent=TRUE ]|
