Audio to video synchronization (also called lipsync ) is a critical aspect of multimedia processing that may be affected anywhere along the media workflow, from capture to delivery. This talk will describe a blackbox-style approach and analysis software based on gstreamer and QR Codes designed to help solve this recurrent problem regardless of the nature of the system.

Florent Thiéry is the C.T.O. and one of the co-founders of UbiCast, a 2007-founded french startup company that builds gstreamer-based solutions designed capture and webcast interactive videos, like the Gstreamer Conference video archive.
