Hi all,<br><br>I am trying to get an application to run on a Max OSX <a href="http://10.5.2." target="_blank">10.5.2.</a> I have downloaded and built the latest tar balls and everything seems to be running fine when I use gst-launch.<br>
<br>
>From within my app, which also runs on Windows, I am doing the following to set the id of the window I want the video to be rendered on:<br><br>- get_bus_set_sync_handler to setup my callback<br>- The callback function looks as follows:<div>

I have found that it never gets to the "GetHandle" line, which leads me to believe that the XOverlay interface does not exist on the Mac.</span></span><br>
</span></div><div><br></div><div>The video does play back just fine in its own window by the way.</div><div><br></div><div>I am using the "autovideosink" for video in my pipeline.</div><div><br></div><div>So the question is: How would one go about setting the render window on a Mac? Since I am also working on a Linux version I would also be interested in a solution for that platform.</div>
