PTS Offset to Add Artificial Delay Not Working

[Michiel Konstapel]

You may need to ensure that you have at least 5 seconds of queue 
capacity, because the buffers will have to be held somewhere before they 
can be processed at the later PTS. I don't know if this needs to be 
before the probed pad, or before the downstream element that cares about 
the PTS (sink, muxer, mixer, encoder, ..?)
Kind regards,
Michiel
