buildPsshAtom

public static byte[] buildPsshAtom​([UUID](https://developer.android.com/reference/java/util/UUID.html "class or interface in java.util")systemId,
                                   @Nullable[UUID](https://developer.android.com/reference/java/util/UUID.html "class or interface in java.util")[] keyIds,

                                   byte[] data)

Deprecated.

Builds a PSSH atom for the given system id, containing the given key ids and data. Parameters:systemId - The system id of the scheme.keyIds - The key ids for a version 1 PSSH atom, or null for a version 0 PSSH atom.data - The scheme specific data.Returns:The PSSH atom.

-

isPsshAtom

public static boolean isPsshAtom​(byte[] data)

Deprecated.

Returns whether the data is a valid PSSH atom. Parameters:data - The data to parse.Returns:Whether the data is a valid PSSH atom.

-

parseUuid

@Nullable
public static[UUID](https://developer.android.com/reference/java/util/UUID.html "class or interface in java.util")parseUuid​(byte[] atom)

Deprecated.

Parses the UUID from a PSSH atom. Version 0 and 1 PSSH atoms are supported.

The UUID is only parsed if the data is a valid PSSH atom.

Parameters:atom - The atom to parse.Returns:The parsed UUID. Null if the input is not a valid PSSH atom, or if the PSSH atom has an unsupported version.

-

parseVersion

public static int parseVersion​(byte[] atom)

Deprecated.

Parses the version from a PSSH atom. Version 0 and 1 PSSH atoms are supported.

The version is only parsed if the data is a valid PSSH atom.

Parameters:atom - The atom to parse.Returns:The parsed version. -1 if the input is not a valid PSSH atom, or if the PSSH atom has an unsupported version.

-

parseSchemeSpecificData

@Nullable
public static byte[] parseSchemeSpecificData​(byte[] atom,[UUID](https://developer.android.com/reference/java/util/UUID.html "class or interface in java.util")uuid)

Deprecated.

Parses the scheme specific data from a PSSH atom. Version 0 and 1 PSSH atoms are supported.

The scheme specific data is only parsed if the data is a valid PSSH atom matching the given UUID, or if the data is a valid PSSH atom of any type in the case that the passed UUID is null.

Parameters:atom - The atom to parse.uuid - The required UUID of the PSSH atom, or null to accept any UUID.Returns:The parsed scheme specific data. Null if the input is not a valid PSSH atom, or if the PSSH atom has an unsupported version, or if the PSSH atom does not match the passed UUID.
