Missing element: MPEG4-GENERIC audio RTP depayloader Gstreamer

When I try to record an RTSP stream with audio and video using gstreamer I get the above error. When only video is recorded it works but when audio pipeline is added the file size becomes zero and the above error is displayed. Further following is also displayed

Missing element: MPEG4-GENERIC audio RTP depayloader WARNING: from element /GstPlayBin:playbin0/GstURIDecodeBin:uridecodebin0: No decoder available for type 'application/x-rtp, media=(string)audio, payload=(int)96, clock-rate=(int)48000, encoding-name=(string)MPEG4-GENERIC, streamtype=(string)5, profile-level-id=(string)1, mode=(string)aac-hbr, sizelength=(string)13, indexlength=(string)3, indexdeltalength=(string)3, config=(string)1188, a-tool=(string)"LIVE555\ Streaming\ Media\ v2016.01.29", a-type=(string)broadcast, x-qt-text-nam=(string)"KMStreaming\ Server", x-qt-text-inf=(string)ch01, clock-base=(uint)3130203504, seqnum-base=(uint)34845, npt-start=(guint64)0, play-speed=(double)1, play-scale=(double)1, ssrc=(uint)3216157947'.

There are two different MPEG4 audio RTP formats in the wild. MP4A-LATM and MPEG4-GENERIC. See RFC 3016 and RFC 3640 respectively.

Looks like GStreamer only supports MP4A-LATM. So basically, yes, the format you are trying to receive is not supported.
