aac file

I have a Ambarella hardware encoder here that produces a RTSP stream. We can't
play the AAC with either faad or avdec_aac, indeed sounds suspect. Attaching
streams just in case.

I extracted the raw AAC from the pcap file using:

gst-launch-1.0 -v filesrc location=rtsp.pcap ! pcapparse src-ip=192.168.1.117
src-port=50000 dst-port=55240 ! application/x-rtp, media=audio, payload=98,
clock-rate=48000, encoding-name=MPEG4-GENERIC, encoding-params='(string)1',
streamtype='(string)5', profile-level-id='(string)41', mode=AAC-hbr,
config='(string)1188', sizelength='(string)13', indexlength='(string)3',
indexdeltalength='(string)3', profile='(string)1', a-type=broadcast,
x-qt-text-inf=stream1, npt-start=0, play-speed=1, play-scale=1 ! rtpmp4gdepay !
aacparse ! filesink location=rtsp.aac
