Hi Thiago,
I tried to run pipeline for specified period of time as suggested by you. But it did not work for me. I want to run pipeline for 15 seconds for that i have done bool flag = gst_element_seek (pipeline, 1.0, GST_FORMAT_TIME, (GstSeekFlags)(GST_SEEK_FLAG_FLUSH | GST_SEEK_FLAG_ACCURATE), GST_SEEK_TYPE_NONE, 0, GST_SEEK_TYPE_SET, 15*GST_SECOND); i have also tried following line of code bool falg = gst_element_seek (vBin, 1.0, GST_FORMAT_TIME, (GstSeekFlags)(GST_SEEK_FLAG_FLUSH|GST_SEEK_FLAG_ACCURATE), GST_SEEK_TYPE_SET, 0 * 15*GST_SECOND, GST_SEEK_TYPE_SET, 15*GST_SECOND); i have run above line of code in once in READY state and once in PAUSED state. I have also tried GST_MSECOND instead of GST_SECOND. But nothing works for me. Please help by telling where i am doing wrong while calling above line of code.

Time should be in nano-seconds .
For more info;

Hi Umakant,
Below code should solve your problem
static gboolean cb_end_stream (GstElement *pipeline) { g_main_loop_quit(loop); } return TRUE; }
Have the above function in your code and add "g_timeout_add" with required value before you do run on main loop. gst_element_set_state(GST_ELEMENT(pipeline), GST_STATE_PLAYING);
g_timeout_add (1000, (GSourceFunc) cb_print_position, pipeline); g_main_loop_run(playerloop); With Warm Regards Jesu Anuroop Suresh "Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius -- and a lot of courage -- to move in the opposite direction." "Anyone who has never made a mistake has never tried anything new."

Hi,
Thanks, As i mentioned in my last reply i have also tried to give time unit as nanosecond. But it did not work for me. It would be great if you can help me by telling what i am doing wrong in seek method to specify the duration of pipeline.

Hi Umakant,
In function 'g_timeout_add' you pass the duration for which you want to run your pipeline,
On timeout you exit from main loop, you don't need to seek. seek will not exit from main loop and will continue to run till it reaches EOS. I have tested the exit using the code as given below
static gboolean cb_print_position (GMainLoop *loop) { g_main_loop_quit(loop); return TRUE; } gst_element_set_state(GST_ELEMENT(pipeline), GST_STATE_PLAYING);
g_timeout_add (1000, (GSourceFunc) cb_print_position, playerloop); g_main_loop_run(playerloop); Correct me If I'm wrong, you want to play a stream for a X duration of time and then exit correct.
Then above code will work for you. With Warm Regards Jesu Anuroop Suresh
