The exact format of the AMR audio data at the OMX level is signaled to OMX decoder as specified in section 4.1.18 of OpenMax IL version 1.1.2 document. Please look at the pvomxaudiodecnode (under nodes) and the existing OMX AMR decoder component under codecs_v2/omx/omx_amr. The OMX audio component is a complete, working implementation of an OMX AMR decoder so it should help resolve uncertainties about how the data is passed and parameters are signaled. The formats and protocols supported for AMR include: 3GP files, IETF storage format files (as defined in RFC-3267 now RFC-4867), and RTP payload format (as defined in RFC-3267 now RFC-4867).
