Field Detail

schemeType

public final java.lang.String schemeType

The protection scheme type, or null if not applicable or unknown.

schemeDataCount

public final int schemeDataCount

Number of DrmInitData.SchemeDatas.

CREATOR

public static final android.os.Parcelable.Creator<DrmInitData> CREATOR

Constructor Detail

DrmInitData

public DrmInitData(java.util.List<DrmInitData.SchemeData> schemeDatas)

Parameters:

schemeDatas - Scheme initialization data for possibly multiple DRM schemes.

DrmInitData

public DrmInitData(java.lang.String schemeType,
                   java.util.List<DrmInitData.SchemeData> schemeDatas)

Parameters:

schemeType - See schemeType.

schemeDatas - Scheme initialization data for possibly multiple DRM schemes.

DrmInitData

public DrmInitData(DrmInitData.SchemeData... schemeDatas)

Parameters:

schemeDatas - Scheme initialization data for possibly multiple DRM schemes.

DrmInitData

public DrmInitData(java.lang.String schemeType,
                   DrmInitData.SchemeData... schemeDatas)

Parameters:

schemeType - See schemeType.

schemeDatas - Scheme initialization data for possibly multiple DRM schemes.

Method Detail

createSessionCreationData

public static DrmInitData createSessionCreationData(DrmInitData manifestData,
                                                    DrmInitData mediaData)

Merges DrmInitData obtained from a media manifest and a media stream.

The result is generated as follows.

1. Include all DrmInitData.SchemeDatas from manifestData where DrmInitData.SchemeData.hasData() is true.
2. Include all DrmInitData.SchemeDatas in mediaData where DrmInitData.SchemeData.hasData() is true and for which we did not include an entry from the manifest targeting the same UUID.
3. If available, the scheme type from the manifest is used. If not, the scheme type from the media is used.

Parameters:

manifestData - DRM session acquisition data obtained from the manifest.

mediaData - DRM session acquisition data obtained from the media.

Returns:

A DrmInitData obtained from merging a media manifest and a media stream.

get

public DrmInitData.SchemeData get(int index)

Retrieves the DrmInitData.SchemeData at a given index.

Parameters:

index - The index of the scheme to return. Must not exceed schemeDataCount.

Returns:

The DrmInitData.SchemeData at the specified index.

copyWithSchemeType

public DrmInitData copyWithSchemeType(java.lang.String schemeType)

Returns a copy with the specified protection scheme type.

Parameters:

schemeType - A protection scheme type. May be null.

Returns:

A copy with the specified protection scheme type.

merge

public DrmInitData merge(DrmInitData drmInitData)

Returns an instance containing the schemeDatas from both this and other. The schemeType of the instances being merged must either match, or at least one scheme type must be null.

Parameters:

drmInitData - The instance to merge.

Returns:

The merged result.
