Deprecated.

Constructs a NAL unit consisting of the NAL start code followed by the specified data. Parameters:data - An array containing the data that should follow the NAL start code.offset - The start offset into data.length - The number of bytes to copy from dataReturns:The constructed NAL unit.

splitNalUnits

@Nullable
public static byte[][] splitNalUnits(byte[] data)

Deprecated.

Splits an array of NAL units.

If the input consists of NAL start code delimited units, then the returned array consists of the split NAL units, each of which is still prefixed with the NAL start code. For any other input, null is returned.

Parameters:data - An array of data.Returns:The individual NAL units, or null if the input did not consist of NAL start code delimited units.
