Hello David,<br>
<br>
To answer your questions:<br>
<br>
1. Why is this happening?<br>
<br>
It's not really easy to tell without seeing your application, and
your dot files are a bit mystifying, as both in PLAYING<br>
and failed the tee that starts your video encoding branch does not
have a sink pad.<br>
<br>
As to the actual issue, you can see that the renegotiation fails
because you're trying to push caps with a different<br>
framerate to the muxer, which let's you know it can't support
changing that on the fly.<br>
<br>
2. How can I fix it?<br>
<br>
Use ges_track_set_restriction_caps, with a fixed framerate.<br>
<br>

<div>I've got a GESTimeline inside of a GstPipeline. I have
attached dot files which shows the pipeline immediately after
each state transition.</div>

<div>I would have provided image files but graphviz doesn't
like these dot files ... but you can use <a
href="http://www.webgraphviz.com/" moz-do-not-send="true">http://www.webgraphviz.com/</a> to
visualize them. They seem accurate except they show
tee_video as disconnected (it is actually connected).</div>

<div>I'm attaching a "small_logs.txt" file (less verbose) and a
"big_logs.txt" file (more verbose). The interesting bits can
be observed in the small file.</div>
