<HTML> <HEAD> </HEAD> <BODY> I’ve got a Gstreamer pipeline grabbing frames of raw video data several times faster than real-time (which is great !) I’ve done this using something like: while( !gst_app_sink_is_eos( sink )) {     buffer = gst_app_sink_pull_buffer( sink );     do_something_with_buffer(...); } This works, but there is no error detection for events other than end of stream. If I were to use a GMainLoop/GMainContext approach instead, is there a Gstreamer event which would tell me every time a frame was ready to be processed ? The GstMessageType documentation seems to hint that GST_MESSAGE_STEP_DONE will do this, but then says it’s not implemented yet... Is there a better way to do this ?
