gstlame.c: In function 'gst_lame_finish_frames':
gstlame.c:1121:7: error: too many arguments for format

The offending lines are:

      GST_DEBUG_OBJECT (lame,
          "unexpected mp3 header with (rate, layer): (%u, %u)",
          rate, version, layer);

The fix is obvious:

      GST_DEBUG_OBJECT (lame,
          "unexpected mp3 header with (rate, version, layer): (%u, %u, %u)",
          rate, version, layer);
