Hello All,
I am prototyping client server streaming using Gstreamer.
Using gst-launch it works fine.
I am constructing same elements in my code as follows :
pipeline = gst_pipeline_new ("rtsp-video-player");
source = gst_element_factory_make ("rtspsrc","rtsp-src");
depay = gst_element_factory_make ("rtph264depay","h264-depay");
decoder = gst_element_factory_make ("ffdec_h264","video-decoder");
sink = gst_element_factory_make ("autovideosink",
"video-output");
if (!pipeline || !source || !depay || !decoder || !sink) {
g_printerr ("One element could not be created. Exiting.\n");
return -1;
}
/* we add all elements into the pipeline */
gst_bin_add_many (GST_BIN (pipeline),
source,depay, decoder, sink, NULL);
gst_element_link_many (source,depay,decoder,sink,NULL);
g_signal_connect (source, "pad-added", G_CALLBACK (on_pad_added),
depay);
static void
on_pad_added (GstElement *element,
GstPad *pad,
gpointer data)
{
gchar *name;
GstPad *sinkpad;
GstElement *depay = (GstElement *) data;
GstElement *fakesink;
name = gst_pad_get_name (pad);
printf(" Dynamic pad %s\n",name);
fakesink = gst_element_factory_make ("fakesink",
"video-output");
if(strncmp("recv_rtp_src_1",name,14)== 0)
{
printf("linking pad\n");
sinkpad = gst_element_get_static_pad (depay, "sink");
printf("Dynamic pad created linking source to %s\n",name);
gst_pad_link (pad, sinkpad);
gst_object_unref (sinkpad);
}
if(strncmp("recv_rtp_src_0",name,14)== 0)
{
printf("linking pad\n");
sinkpad = gst_element_get_static_pad (fakesink, "sink");
printf("Dynamic pad created linking source to %s\n",name);
gst_pad_link (pad, sinkpad);
gst_object_unref (sinkpad);
}
}
while running my application I am facing gst_rtp_jitter_buffer_loop is going
on while..
below i am mentioning the error message.

1.what was the reason the gst_rtp_jitter_buffer_loop is going continous
loop?.
2.please guide me how to solve this issue.
I am waiting your favourably reply
Thanks in advance
