You can easily reproduce this scenario on your end using the test collateral in my google-drive folder (https://drive.google.com/drive/u/2/folders/1cAx-ubSH0q1T13TQjmUFyks6D5y3C_LE)  Youi can copy the media files into a folder "/var/panopto/media-unittests/tc-composition/04" to match the paths in the timeline.xges file.

It stays frozen until the next slide transition, at which time it switches to a new frame, but the video is remains frozen.  The video never un-freezes.  On each slide transition, it simply displays a new frame but there is never any motion to the video ... it is always frozen on a single frame.

However, I have another project which constructs the GESTimeline programmatically, and then runs it inside of a GstPipeline.  You will find the applications logs (including Gstreamer logs) inside the folder (logs/*.log).

I see plenty of warnings in the logs/*.log file which I have saved off.  I wonder if those logs provide a clue about the problem that I'm facing.  I also saved off the pipeline graphs in the logs folder (including SVG files).
