Using GST 1.11,
I have created a ghost pad and confirmed it is working by the following
gchar *ghost_pad_1_name = NULL;
ghost_pad_1_name = "myGhostPad'
ghost_pad_1 = gst_ghost_pad_new (ghost_pad_1_name, pad_src_1);
if(GST_PAD_DIRECTION(ghost_pad_1) == GST_PAD_SRC){
printf("Ghost is SRC -> correct\n"); // Correct
}
printf("Ghost Pad Name = %s\n",GST_ELEMENT_NAME(ghost_pad_1)); // myGhostPad
however trying to get the element by using the following returns NULL
GstElement *TestGhostPad = gst_bin_get_by_name (ghost_pad_1_name);
if (!TestGhostPad){
printf("Ghost Pad is NULL\n"); // This is called
}
if (TestGhostPad){
printf("Ghost Pad is NOT NULL\n");
}
Am I using this function correctly? Is there another method to get the
Ghost Pad by name.
thanks Art
