[gst-devel] Duration of Pipeline

Mon Jan 17 08:04:01 CET 2011

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
