Docs For Class ISO14496_Box

Description

Each entry contains the location and the presentation time of the random accessible sample. It indicates that the sample in the entry can be random accessed. Note that not every random accessible sample in the track needs to be listed in the table.

The absence of the Track Fragment Random Access Box does not mean that all the samples are sync samples. Random access information in the Track Fragment Run Box, Track Fragment Box and Track Fragment Box shall be set appropriately regardless of the presence of this box.
