Detailed Description

Functional class for pasp-box (Picture Aspect Ratio Box) support.

A pasp-box is expected to be contained in a video track which is one of the following coding types:

• avc1
• mp4v

This implementation assumes a maximum count of 1 for VideoSampleEntry of the supported codings.
