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

[Adrian Daerr]

Hi Peter,

Not sure whether the cause is the same in your case, but when I stumbled 
across the same assertion error, it was because I had forgotten to set 
the 'format' property on my appsrc to one of the values specified here:

http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstFormat.html

See the following thread for more details:
http://gstreamer-devel.966125.n4.nabble.com/Re-videoflip-causes-critical-errors-in-gstreamer-1-0-tt4661512.html

hth & good luck,
Adrian
