< VIDEOMIXER > aggregator gstaggregator.c:2052:gst_aggregator_query_latency_unlocked: Latency query failed
I have constructed the following pipeline, it works as expected with one issue, I am getting "aggregator gstaggregator.c:2052:gst_aggregator_query_latency_unlocked: Latency query failed" warning constantly (on each buffer). When I removed Videomixer from the pipeline "Latency query failed" is gone. I am trying to identify and solve this warning but I could not, It only happens when I introduce videomixer in the pipeline. Is there something I am doing wrong to escalate latency query to fail?
Attaching my DOT file (paused -> playing ) of the pipeline and my gst-lunch command.
looking forward to your comments and suggestions. Gstreamer version ( 1.19.2 )
