You can either use clutter-gst, (if you are using gstreamer 1.6) glimagesink, or craft your on video sink.
The simplest way is, if you use clutter, embedded a cluttervideosink actor in your code. If you write your own video sink, you would handle the GstVidoeGLTextureUpload meta: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstvideometa.html#GstVideoGLTextureUpload WebKitGTK+ does that with its own video sink (though, it is moving to use glimagesink). In the case of using glimagesink, you can connect the 'client-draw' signal and render the given texture: http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/tests/examples/gl/sdl/sdlshare2.c?h=1.6 There's another option, juggling with the GL context: http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/tests/examples/gl/sdl/sdlshare.c?h=1.6 vmjl On 09/29/15 at 12:38pm, Dolevo Jay wrote: > Hi, > In my device, I receive video streams from different sources (local or > remote).
