Hello,<div><br></div><div>I've been using gstreamer on Linux with great satisfaction. Recently I acquired a Mac and wanted to see how easy it would be to rebuild the application using the Cocoa layouts, preserving as much as possible of the architecture, but upgrading some user interface elements here and there.</div>
<div><br></div><div>I have an rtsp video stream that's transmitted wirelessly and which, on Linux, is displayed straight onto the window frame. It is using the glimagesink for this purpose, so that I can add some relatively simple 3D elements to this video. I'm using gstreamer, because this allows me to have control over latency and other parameters, which are important here.</div>
<div><br></div><div>I was looking to do the same thing on the Mac OSX and have finally managed to get this compiling in Xcode using the excellent mac OSX install packages here:</div><div><br></div><div><a href="http://docs.gstreamer.com/display/GstSDK/Installing+on+Mac+OS+X">http://docs.gstreamer.com/display/GstSDK/Installing+on+Mac+OS+X</a></div>
<div><br></div><div><br></div><div>In some testing, I inadvertently had a mix of macports still available on the system, which caused me to think that glimagesink was available, but later discovered my flaw. It seems that the glimagesink plugin is not available in the SDK version. Is this not supposed to be used anymore or are there other issues on Mac? The code did seem to have a specific "cocoa" example/test available.</div>
<div><br></div><div><br></div><div>What I'm looking for is how to make a simple application with a couple of gui elements and a large OpenGL component in the middle that plays the video and also allows me to perform some additional, custom drawing over that. Ideally, this should a subclass of NSOpenGLView that I can drag onto a window and through some additional code hook up to a gstreamer pipeline and start playing. Most examples I saw create their own main windows and then use the entire area for drawing, which is not what I want to use. Also, a lot of examples were written prior to ARC and some other improvements on Mac OSX.</div>
<div><br></div><div>If that's a yes, is there a general strategy for hooking up the NSOpenGLView to a gstreamer pipeline without creating a window in code in a separate "main" window in C code? The idea is to just use the more Apple-like NIB files to define the windows and restrict the GStreamer stuff within the UI component. I'd like to have as little impact as possible on the Mac development process/XCode.</div>
<div><br></div><div>Thanks for your help,</div><div><br></div><div>-- <br>Gerard Toonstra<br><br>
