Checking the type of decoders used by MPEG4 audio and video files

[sanjay.saha at wipro.com]

Hi,

How can we check whether
a particular MPEG4 audio file is of one of the following types:
a) MPEG4 AAC LC
b) MPEG4 - HE AAC
c) MPEG4 - AAC LTP
and MPEG4 video file is of type "MPEG4 AVC (AAC LC Assoc Audio)"?

eg: I tried to play one MPEG4 audio file using gst-launch utility in verbose mode.
Please find attached the log message.
>From the log, I found that it is using the plugin MFW_GST_AAC_PLUGIN from which we can infer that it is using AAC decoder but cannot distinguish further between (a) - (c)?

Regards,
Sanjay
