I don't think the qos formula is in fault here. It's just decoder which output
old frames causing the sink to think it is late.

Doing this will also remove the 'real' QOS event, ie performance issue...
I wonder about using the DISCONT flags. Since live src doesn't have received
data for a while, it could mark the discont and the decoder/intermediate
element may flush to avoid sending old video data to sink.
