  [GStreamer] Video sink should discard late frames to avoid audio and video desynchronization
https://bugs.webkit.org/show_bug.cgi?id=247740

Reviewed by Philippe Normand.

In some cases and/or platforms video frames can arrive late and if are not discarded, they end up being painted and
there can be a/v desynchronization. Setting the max-lateness property forces the sink to discard late frames and solve
the problem.
