Answer 1

Your code is not handling return codes from the functions. As a result your in the dark when it fails. Anyway in your code you forgot to link the elements. Right after line 70, also do gst_element_link_many(....);

Answer 2

Traditionally, the GStreamer package doesn't include support for MP3 . However, you can go after codecs and plugins to make it support.
