Hi,
Thank you for the response.
In the code below, I use ping to wait for the disconnected camera to come back and then switch the pipeline to PLAYING. This goes fine. The camera comes back and the pipeline switches into PLAYING mode successfully. But I see no streaming. The new_buffer callback is not occuring.
static void appsink_eos(GstAppSink * appsink, gpointer user_data)
{
printf("app sink received eos\n");
eos = 1;
delete restart_handle;
restart_handle = new std::thread{restart_thread};
restart_handle->detach();
}
void restart_thread()
{
wait_for_camera_ON( ip_from_url(g_camera_url));
std::cout << "camera back ON." << std::endl;
sleep(40);
std::cout << "setting pipeline to PLAYING" << std::endl;
eos = 1;
gst_element_set_state((GstElement*)gst_pipeline, GST_STATE_PLAYING);
while(eos != 0)
{
GstStateChangeReturn ret = gst_element_get_state((GstElement*)gst_pipeline, nullptr,
nullptr, GST_CLOCK_TIME_NONE);
if(ret == GST_STATE_CHANGE_SUCCESS)
{
std::cout << "state change success." << std::endl;
eos = 0;
break;
}
else if(ret == GST_STATE_CHANGE_FAILURE)
{
std::cout << "state change failure.. stopping" << std::endl;
//end_capture();
exit(0);
}
else
{
std::cout << "Intermediate return code.. waiting 5 more secs.." << std::endl;
sleep(5);
}
}
}
This is the output:

setting pipeline to PLAYING
state change success.
(--- long wait without any output here --- )
^C
I am not setting the pipeline to NULL in the modified logic.
Do you have any suggestions here?
Thank you.
