Tim Malseed 6455671ece Update mp4properties.cpp (#893) 
When parsing mp4 media header version 1 (mdhd) atoms, the timescale (unit) is parsed as a `LongLong` (8 bytes), but instead should be a `UInt` (4 bytes). This results in an incorrect timescale, and also pushes the offset of the duration (length) off by 4 bytes.

The end result being that the AudioProperties track length for mp4's with mdhd v1 comes back as 0.
