I receive them and show them like below:* p_description = "playbin uri=%s " %uri + "mute=true" new_pipeline = Gst.parse_launch(p_description) new_pipeline.name = "pipeline_" + str(self.n_branch) videobin = Gst.Bin.new("videobin"+str(self.n_branch)) timeoverlay = Gst.ElementFactory.make("timeoverlay","timeoverlay"+str(self.n_branch)) videobin.add(timeoverlay) pad = timeoverlay.get_static_pad("video_sink") ghostpad = Gst.GhostPad.new("sink", pad) videobin.add_pad(ghostpad) queuesink = Gst.ElementFactory.make("queue","queuesink"+str(self.n_branch)) videobin.add(queuesink) videosink = Gst.ElementFactory.make("autovideosink","autovideosink"+str(self.n_branch)) videobin.add(videosink) timeoverlay.link(queuesink): queuesink.link(videosink): new_pipeline.set_property("video-sink", videobin) # Sets buses for events on the pipeline # bus = new_pipeline.get_bus() # bus.add_signal_watch() # bus.enable_sync_message_emission() # bus.connect("message", self.on_message) # bus.connect("sync-message::element", self.on_sync_message) new_pipeline.set_state(Gst.State.PLAYING) * I'm having some issues because I used xvimagesink and my application crashes sometimes on a particular .mp4 configuration:* 0:00:00.558593949 616 0x1082f70 WARN basesrc gstbasesrc.c:2943:gst_base_src_loop:<udpsrc1> error: Errore interno nel flusso di dati. 0:00:00.558637417 616 0x1082f70 WARN basesrc gstbasesrc.c:2943:gst_base_src_loop:<udpsrc1> error: streaming task paused, reason not-linked (-1) 0:00:00.569523427 616 0x1068770 WARN basetransform gstbasetransform.c:1414:gst_base_transform_setcaps:<videoconvert0> transform could not transform video/x-raw(memory:VASurface), format=(string)I420, width=(int)1280, height=(int)720, interlace-mode=(string)progressive, pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)mpeg2, colorimetry=(string)bt709, framerate=(fraction)0/1 in anything we support 0:00:00.569718285 616 0x1068770 WARN basetransform gstbasetransform.c:1414:gst_base_transform_setcaps:<videoconvert0> transform could not transform video/x-raw(memory:VASurface), format=(string)I420, width=(int)1280, height=(int)720, interlace-mode=(string)progressive, pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)mpeg2, colorimetry=(string)bt709, framerate=(fraction)0/1 in anything we support * If I change to autovideosink the problem is resolved! But I have to change my application because autovideosink hasn't "set_window_handle(xid)" method. So I add "bus.connect("sync-message::element", self.on_sync_message)" to capture my imagesink so:* if message.get_structure().get_name() == 'prepare-window-handle': newimagesink = message.src * But I'm getting another crash:* [xcb] Unknown sequence number while processing queue [xcb] Most likely this is a multi-threaded client and XInitThreads has not been called [xcb] Aborting, sorry about that. python3.4: ../../src/xcb_io.c:274: poll_for_event: asserzione "!xcb_xlib_threads_sequence_lost" non riuscita. * If I add autovideosink slowly the problem doesn't appear... Is there someone who can help me?
