I'm calling seek_simple from my bus callback, does that ensure I'm
calling from the correct thread or is there something else I need
to do?<br>

<pre wrap="">Hello,
I'm writing a video player application that dynamically plays videos
based on user commands, looping each video and crossfading between them.
My pipeline is rather complex, please see the image here
<a class="moz-txt-link-rfc2396E" href="https://owncloud.isrv.pw/public.php?service=files&t=54bceac798e5501daa196dffc5a1a242&download"><https://owncloud.isrv.pw/public.php?service=files&t=54bceac798e5501daa196dffc5a1a242&download></a>
for the details. In my Python code, I've inserted a probe after my
uridecodebin elements to catch EOS events, when an EOS event comes
through I post a message to the bus and drop the EOS. When the message
is received, the bus callback calls seek_simple() on the message's
source uridecodebin. However, the uridecodebin is never seeks but
instead hangs. Please see my example script here
<a class="moz-txt-link-rfc2396E" href="https://owncloud.isrv.pw/public.php?service=files&t=a10f944344286f87bb7583ecc8eede5c&download"><https://owncloud.isrv.pw/public.php?service=files&t=a10f944344286f87bb7583ecc8eede5c&download></a>,
which demonstrates the issue I'm having. How can I seek the uridecodebin
back to the start of the file?

You can't seek in a pipeline from the streaming thread, otherwise it
will deadlock. You'll have to defer the seeking to another thread and
then it should work.
If it still doesn't, please provide backtraces from all threads at the
time it deadlocks.
