title: How to detect AAC audio profile and ensure Android compatibility
body: <p>I am having problems figuring out how to detect if an AAC audio source is compatible with Android. The supported media formats <a href="http://developer.android.com/guide/appendix/media-formats.html" rel="nofollow">page</a> for android says 'AAC LC/LTP' when delivered as 3GP, MPEG4 or ADTS raw AAC. It appears the LC means 'Low Complexity" and LTP means "Long Term Prediction" but, my biggest frustration is determining what AAC profiles/modules are supported on Android. When I run the input into ffmpeg, i see its AAC, but no extended information about the AAC. An example source is <a href="http://6693.live.streamtheworld.com:80/WTMJAMAAC_SC" rel="nofollow">http://6693.live.streamtheworld.com:80/WTMJAMAAC_SC</a> . Anyone have any ideas?</p>
