I am still in the process of streamlining the build and findig out what is exactly needed. In an atempt to make the image smaller I omitted the gstreamer-plugin other than base from optimize=size and small, I will change this to a fixed dependency with ServiceMP3. Thank you for you input.
Meanwhile I have solved the problem in post #42. gst_init was called with argc equalling a large number, whereas it was originally was called with the calling parameters of E2. Patching the gst_init parameters to NULL fixed this.
