In general this looks ok, but consider using decodebin instead of manual
depayloader and decoder. And add a videoconvert element in front of the
sink just in case.

Otherwise it would help to get GStreamer debug logs, you can enable them
with gst_debug_set_default_threshold(GST_LEVEL_DEBUG) for example. And
they will appear on "adb logcat".
