GStreamer-CRITICAL **: gst_segment_to_running_time: assertion `segment->format == format' failed

[Peter Maersk-Moller]

Hi Adrian.

The initial suggestion in the thread to add identity element had no impact.
I also tried to replace the last part of my pipeline with a fakesink with
sync=false and I have no do-timestamp in the pipeline so fiddling with
timestamps (using a gst-launch) pipeline doesn't appear to be a way. Tried
also setting max-time-size=0 for the queue, as I'm not certain why the
queue/fakesink produce the critical message. But to no avail.

Best regards
Peter
