The only side effect is you'll need some "major" tweaks to use it in QML (of course, only if you need it).<br> <br> <div class="moz-cite-prefix">On 04/09/2012 08:07, Cedric Hombourger wrote:<br> </div> <blockquote cite="mid:CED26D6C-475D-4BDE-8A8D-F4AD9BE81E9A@gmail.com" type="cite"> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <div><br> </div> QtGstreamer is a project aiming at creating a C++ API (with a Qt style) for GStreamer allowing full control of the pipeline(s) created.
