* Make the example tolerant of videos missing parts
Some videos are missing certain parts that the example was assuming would be
present. This change makes all such access conditional on the parts being
present. Also added the display of the box version and the creation time in
a human-readable format. This serves to demonstrate the logic for converting
the MP4 epoch (1904-01-01) to Unix epoch (1970-01-01).
* Show creation time as Unix time only
