Description | Constants (details) Vars | Methods (details)
BASE_DATA_OFFSET = 0x1 (line 82)

Indicates indicates the presence of the baseDataOffset field. This provides

an explicit anchor for the data offsets in each track run (see below). If not provided, the base-dataoffset for the first track in the movie fragment is the position of the first byte of the enclosing Movie Fragment Box, and for second and subsequent track fragments, the default is the end of the data defined by the preceding fragment. Fragments inheriting their offset in this way must all use the same data-reference (i.e., the data for these tracks must be in the same file).

DEFAULT_SAMPLE_DURATION = 0x20 (line 98)

Indicates the precense of the defaultSampleFlags field.

DEFAULT_SAMPLE_DURATION = 0x8 (line 92)

Indicates the precense of the defaultSampleDuration field.

DEFAULT_SAMPLE_SIZE = 0x10 (line 95)

Indicates the precense of the defaultSampleSize field.

DURATION_IS_EMPTY = 0x10000 (line 105)

Indicates that the duration provided in either defaultSampleDuration, or by the defaultDuration in the Track Extends Box, is empty, i.e. that there are no samples for this time interval.

SAMPLE_DESCRIPTION_INDEX = 0x2 (line 89)

Indicates the presence of the sampleDescriptionIndex field, which over-rides, in this fragment, the default set up in the Track Extends Box.
