The element factory names are dynamic and might change between hardware
and software versions. You will have to either implement some kind of
autoplugging mechanism with the GstRegistry and GstElementFactory API,
or just use decodebin.

Independent of that it could of course also be that something in the
Lollipop upgrade broke something. To know that we would need to get a
GStreamer debug log, and also which GStreamer version are you using?


You can get a debug log with the relevant information by calling
gst_debug_set_threshold_from_string("2,amc*:6", TRUE)
somewhere in the very beginning of your application. Before
GStreamer.init() / gst_init() is called.
