When I play from command line using the pipe: "gst-launch filesrc location=/home/ashwini/streams/output.ts ! mpegtsparse ! mpegtsdemux ! decodebin ! ffmpegcolorspace ! ximagesink" The video is displayed well.  But when i try to achieve the same pipe thru the application, It fails. The code snippet of pipelie creation is as follows: pipeline = gst_pipeline_new ("gst-player"); //gst_debug_set_default_threshold(GST_LEVEL_DEBUG); gst_debug_set_threshold_for_name("mpegtsparse",GST_LEVEL_DEBUG);     src = gst_element_factory_make ("filesrc", NULL);     g_assert (src); g_print("URI = %s\n",uri);     g_object_set (G_OBJECT (src), "location", uri, NULL);     parse = gst_element_factory_make ("mpegtsparse", NULL);     g_assert (parse);     demux = gst_element_factory_make ("mpegtsdemux", NULL);     g_assert (demux);     dec = gst_element_factory_make ("decodebin", NULL);     g_assert (dec);     csp = gst_element_factory_make ("ffmpegcolorspace", NULL);     g_assert (csp);     videosink = gst_element_factory_make ("ximagesink", NULL);     g_assert (videosink);     /* Adding elements to the pipeline */     gst_bin_add_many (GST_BIN (pipeline), src, parse, demux, dec, csp, videosink, NULL);     //  gst_bin_add_many (GST_BIN (pipeline), src, videosink, NULL);    // g_assert (gst_element_link_many (src, parse, demux, dec, csp, videosink, NULL));     g_assert (gst_element_link (src, parse));     g_assert (gst_element_link (parse, demux));     gst_element_link (demux, dec);     (gst_element_link (dec, csp));     (gst_element_link (csp, videosink));     if (GST_IS_X_OVERLAY (videosink))     {         gst_x_overlay_set_xwindow_id (GST_X_OVERLAY (videosink), GPOINTER_TO_INT (window));     }     gst_element_set_state (pipeline, GST_STATE_PLAYING); What could be causing it to fail. (In the above snippet described, I have used the gst-player code and modified the pipe to current state) Any help is appreciated.<o:p></o:p> <o:p> </o:p> </div> </div> You need to listen for 'pad-added' signal from the decoder and check the gst_element_link() calls for success. <a href="http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/chapter-helloworld.html" target="_blank">http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/chapter-helloworld.html</a> -- Nathanael d.
