You don't really want queue to leak buffers anyway. That's just a bad

My use has nothing to do with QoS, I am using queue in buffer leak
mode to implement a pre-trigger buffer downstream of a live source.
When an event occurs I have N sec of video from before the event
stored in the queue so when I unblock the src pad I record the video
buffers stored in the queue followed by the real time data from the
live source until the event ends at which time I again block the src
pad. I don't want any more than N sec worth of pre-trigger, just a
short period of time up to 10 seconds before the trigger point. If
nothing interesting is happening possibly for hours the video can
fall off the end of the queue. The queue element is perfect for this
purpose.<br>
