But elements in you pipeline have no name. If you will make elements like this GstElement* element= gst_element_factory_make(videotestsrc , "videotestsrc"); you can find it latter by name GstElement* sink = gst_bin_get_by_name(GST_BIN(pipeline), "<span style="font-family: Calibri, Arial, Helvetica, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; color: rgb(33, 33, 33); font-size: 15px;">videotestsrc"); Mikl </div> <hr style="display:inline-block;width:98%" tabindex="-1"> <div id="divRplyFwdMsg" dir="ltr">From: gstreamer-devel <gstreamer-devel-bounces@lists.freedesktop.org> on behalf of Marcin Rosner <rsnr@tlen.pl> Sent: Thursday, October 27, 2016 2:29:11 PM To: gstreamer-devel@lists.freedesktop.org Subject: gst_bin_get_by_name returns NULL <div> </div> </div> <div>Hi all, I am using gstreamer 1.2.4 and the function gst_bin_get_by_name always returns NULL when I pass a valid and working pipeline to it. Here a code which I took from a gstreamer tutorial and modified a bit: gst_init (NULL, NULL); GstElement* pipeline = gst_parse_launch("videotestsrc ! xvimagesink", NULL); GstElement* sink = gst_bin_get_by_name(GST_BIN(pipeline), "sink"); gst_element_set_state (pipeline, GST_STATE_PLAYING); GMainLoop *loop; loop = g_main_loop_new (NULL, FALSE); g_main_loop_run (loop); The code works and a test video is shown on a screen, but sink is NULL as also sinkpads and srcpads from the pipeline. Why is that? How should I do it properly?</div> </body> </html>
