<div dir="ltr"><div><div><div>Hi Adrian. </div>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. </div>Best regards </div>Peter <div><div><div> </div></div></div></div><div class="gmail_extra"> <div class="gmail_quote">On Mon, Sep 23, 2013 at 4:13 PM, Adrian Daerr <<a href="mailto:adrian.daerr@univ-paris-diderot.fr" target="_blank">adrian.daerr@univ-paris-diderot.fr</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">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: <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstFormat.html" target="_blank">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/gstreamer-GstFormat.html</a> See the following thread for more details: <a href="http://gstreamer-devel.966125.n4.nabble.com/Re-videoflip-causes-critical-errors-in-gstreamer-1-0-tt4661512.html" target="_blank">http://gstreamer-devel.966125.n4.nabble.com/Re-videoflip-causes-critical-errors-in-gstreamer-1-0-tt4661512.html</a> hth & good luck, Adrian<div><div class="h5"> On 23.09.2013 15:44, Peter Maersk-Moller wrote: </div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"> Hi. I have a pipeline that reports: GStreamer-CRITICAL **: gst_segment_to_running_time: assertion `segment->format == format' failed I tried to search mailing list and the web, but found no obvious ideas to what it means. What does it mean? And how does one goes around mitigating this? It should be said that the pipeline plays. The version used is 1.1.90 The pipeline is shown below. I notice that the CRITICAL message is no longer present, if I remove the pipeline elements AFTER the 'filesink' element. So quite likely something between decodebin and shmsink provokes the critical message, but I'm not really sure what to look for.
