Description
+++ This bug was initially created as a clone of Bug 752791 +++
Basesink drops buffers before segment, this can be harmful for streams that have keyframes. Appsink, network sinks and any other sinks that can handle any format would drop relevant data before the segment and rendering might not work as expected.
