I was playing around with the source code of deepstream reference app which comes with deepstream sdk.
I am using live rtsp sources as input. The app works fine for the initial run.
So as given in the source code -
when the app encounters an error it goes to done and performs the required cleanup.
done:
g_print ("Quitting\n");
g_source_remove(event_source_id);
g_source_remove(timeout_source);
for (i = 0; i < num_instances; i++) {
if (appCtx[i]->return_value == -1)
return_value = -1;
int return_after_destroy = destroy_pipeline (appCtx[i]);
g_mutex_lock (&disp_lock);
if (windows[i])
XDestroyWindow (display, windows[i]);
windows[i] = 0;
g_mutex_unlock (&disp_lock);
g_free (appCtx[i]);
}
g_mutex_lock (&disp_lock);
if (display)
XCloseDisplay (display);
display = NULL;
g_mutex_unlock (&disp_lock);
g_mutex_clear (&disp_lock);
if (main_loop) {
g_main_loop_unref (main_loop);
}
if (ctx) {
g_option_context_free (ctx);
}
if (return_value == 0) {
g_print ("App run successful\n");
} else {
g_print ("App run failed\n");
}
I wish to have a restart function in the app so that when it crashes it again restarts the process after sometime. In order to do that, I wrote a wrapper main function and changed the original function to some other function.
// updated main
int main(int argc, char* argv)
{
some_other_function(argc, argv);// original main
}
and now am calling some other function again whenever the app goes to the done state. The app runs fine for the first time , but when I am recalling the function for the second time, I get the create pipeline failed message. I found out that gst_pipeline_new is unable to create a new pipeline. How to solve this ?
