Constructor Details

Chunk

public Chunk(AbstractQuickTimeStream.Sample firstSample,
 int sampleDescriptionId)

Creates a new Chunk.

Parameters:

firstSample - The first sample contained in this chunk.

sampleDescriptionId - The description Id of the sample.

Chunk

public Chunk(AbstractQuickTimeStream.Sample firstSample,
 AbstractQuickTimeStream.Sample lastSample,
 int sampleCount,
 int sampleDescriptionId)

Creates a new Chunk.

Parameters:

firstSample - The first sample contained in this chunk.

sampleDescriptionId - The description Id of the sample.

Method Details

maybeAddSample

public boolean maybeAddSample(AbstractQuickTimeStream.Sample sample,
 int sampleDescriptionId)

Returns true, if the sample was added to the chunk. If false is returned, the sample must be added to a new chunk.

A sample can only be added to a chunk, if it has the same sample description Id as previously added samples, if the capacity of the chunk is not exceeded and if the sample offset is adjacent to the last sample in this chunk.

maybeAddChunk

public boolean maybeAddChunk(AbstractQuickTimeStream.Chunk chunk)

Description copied from class: AbstractQuickTimeStream.Group

Returns true, if the chunk was added to the group. If false is returned, the chunk must be added to a new group.

A chunk can only be added to a group, if the capacity of the group is not exceeded.

Overrides:

maybeAddChunk in class AbstractQuickTimeStream.Group

getChunkOffset

public long getChunkOffset()

Returns the offset of the chunk in the movie file.
