Your current log is 100mb big and very very long. Would be easier to debug with a lower debug level. Thanks, Luis On 11 July 2014 08:35, David W.

It uses playbin and the 'about-to-finish' signal to change URIs, as the various examples and advice about this shows. Unfortunately, I'm seeing a 5-10 frame 'pause' when switching URIs. What seems to be happening is that the sink stops rendering frames for a brief period, leaving a static frame visible, then 'catches up' and starts rendering again, skipping the first few frames of the next clip. I tried taking the same clips and playing them with gst-play-1.0 --gapless and I get the same result. My question is, how can I narrow down what's going on here? And is there anything I can do to get frame-perfect transitions? I created a debug log with GST_DEBUG=5 here: <a href="https://www.dropbox.com/s/" target="_blank">https://www.dropbox.com/s/</a> 0rdzlrcaz77wbkc/dbg.out.gz Unfortunately, I'm not quite sure how to interpret this output.
