AVAsset's isPlayable is not accurate.

Product:iOS SDK Product Version:8.1.3
Classification:Other Bug Reproducible:Always
 
Summary:
AVAsset’s isPlayable method returns NO for certain audio files which play fine through AVPlayer.  In particular extended AACs suffer from this.

Steps to Reproduce:
1. Create an AVAsset with an extended AAC (grab one from the AAC feed here http://www.macobserver.com/tmo/features/mac_geek_gab_free/) 
2. Check `isPlayable`
3. Try playing it anyway.

Expected Results:
1. `isPlayable` should return YES

Actual Results:
1. `isPlayable` returns NO, but the file is in fact playable

Notes:
A work around is to also check `asset.tracks.count == 0` to confirm that the asset is not playable, but that is probably letting through some assets that have a track that we can’t play.

An example project is attached which demonstrates this issue reliably.
