There is two way : 1. you can delete old pipeline ,delete the pipeline object and set new video path and with creating new pipeline after getting EOS. 2. you can do like this after getting EOS: gst_element_set_state( pipeline, GST_STATE_NULL ); gst_element_set_state( pipeline, GST_STATE_READY); then set new video path gst_element_set_state( pipeline, GST_STATE_PLAY); Definitly it will work. <div class="gmail_quote">On Wed, Jul 15, 2009 at 5:13 PM, ldac <<a href="mailto:ldacvs@gmail.com">ldacvs@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hi all, I have programmed a C application where I capture video, then I encode it, and finally I stream it using an udpsink element. It works, but if I stop the pipeline (sending it EOS) and then start it again, I get old video, when it should be alive. How can I clean absolutely the pipeline to avoid this? My code is something like this: ... // Create the elements pipeline = gst_pipeline_new( "pipe" ); video_src = gst_element_factory_make( "mfw_v4lsrc", "video-source" ); video_enc = gst_element_factory_make( "mfw_vpuencoder", "video-encoder" ); sink = gst_element_factory_make( "udpsink", "sink" ); // Add the elements to the pipeline gst_bin_add_many( GST_BIN( pipeline ), video_src, video_enc, sink, NULL ); gst_element_link_with_filter( video_src, video_enc, &settings ); gst_element_link( video_enc, sink ); ... // Start/Stop the video stream while ( 1 ) { if ( do_stream ) { gst_element_set_state( pipeline, GST_STATE_PLAYING ); g_main_loop_run( loop ); gst_element_set_state( pipeline, GST_STATE_NULL ); } else sleep( 1 ); } ... Another function changes the variable 'do_stream' to true/false, and send also the EOS signal to the pipeline when required. So, specifically, my question is: What do I clean my pipeline when stopped to start again with the buffers and everything clean? Do I have to delete the pipeline object and do I have to create and link all the pipeline again? Thank you very much. All the best.
