</div>Yes, that's correct. videomixer is only forwarding the event but that<br>
should actually be fine as it operates on the running time of all<br>
streams.<br>

<br>
</div>Yes please, also a debug log with GST_DEBUG=6 could be helpful.<br>

</div>xvimagesink is sending a QoS even for every single frame it receives.<br>
Upstream elements can then decide based on the timestamps in the QoS<br>
event if they should drop frames and skip forward (because they would<br>
arrive too late in the sink anyway) or degrade quality of a filter<br>
or ...<br>
