I'm using separate custom pipelines (N for video, one for audio), i.e. without using the decodebin-wrapped object (clutter video sink). The audio one is live from end to end, the video ones are "best effort", and i never noticed any desynchronization. > Is there any way to enable synchronization on the clutter video sink and > keeping sound ?

Btw the gst-gl-plugins branch is open now (git:// diracvideo.org/git/gst-plugins-gl.git), there are interesting elements: * glupload (gst->gl context) * gldownload (gl context->gst) * glcolorscale: accelerated colorspace conversion and scaling Not sure about that but these elements are/will be in conformity with gstreamer qos & synchronization facilities. Food for thought... Florent
