This is the code and i am able to get only buffer of image but hoe to display it I am not able to get around it...............please help me out on this
#include <gst/gst.h>
GstElement *pipe, *dec, *sink, *src;
static void
print_one_tag (const GstTagList * list, const gchar * tag, gpointer user_data)
{
if(!strcmp(tag,"image")) {
guint i;
const GValue *val;
g_printf("Image Detected");
i=gst_tag_list_get_tag_size(list,tag);
g_printf("\n%d",i);
val = gst_tag_list_get_value_index(list, tag, 0);
g_printf("\n%s",GST_BUFFER_DATA (gst_value_get_buffer (val)));
}
}
static void
