Public constructors

Factory

public Factory(DataSource.Factory dataSourceFactory)

Creates a new factory for DashMediaSources.

The factory will use the following default components:

Parameters
DataSource.Factory dataSourceFactory

A factory for DataSource instances that will be used to load manifest and media data.

Factory

public Factory(
    DashChunkSource.Factory chunkSourceFactory,
    @Nullable DataSource.Factory manifestDataSourceFactory
)

Creates a new factory for DashMediaSources.

The factory will use the following default components:

Parameters
DashChunkSource.Factory chunkSourceFactory

A factory for DashChunkSource instances.
@Nullable DataSource.Factory manifestDataSourceFactory

A factory for DataSource instances that will be used to load (and refresh) the manifest. May be null if the factory will only ever be used to create media sources with sideloaded manifests via createMediaSource.
