<p>That is correct,<br>
<br>
Qt and GStreamer are currently built with different c++ exception
handling.<br>
<br>
In order to have compatible exception handling you need to build
*all* components with the same exception handling which would
involve either recompiling Qt with SJLJ or recompiling GStreamer
with DW2.<br>
<br>
If you're attempting to build the qt plugin (for qmlglsink and
qmlglsrc) there's a qmake .pro file in there for one to build that
plugin with whatever Qt was built with. That doesn't help with
any of the other c++ plugins though.<br>

<div class="">My first idea was that this is related to the
