Steps to reproduce:
1. Open the attached “AVAssetLeak” projet
2. In Build Settings enable Development Build
3. Build the project
4. Open the build in Xcode and deploy it to the device
5. Open Xcode > Open Developer Tool > Instruments and choose Allocations for the profiling template
6. Start an immediate mode recording
7. In the Detail filter search write “av”
8. In the Player press the “Play” and “Stop” buttons while observing memory usage (total bytes) in the Instruments window

Expected result: Memory usage remains stable or is released
Actual result: Memory usage increases every time the “Play” button is pressed and is never reduced
