Constants

OBU_FRAME

public static final int OBU_FRAME = 6

OBU type frame.

Public methods

split

public static List<ObuParser.Obu> split(ByteBuffer sample)

Splits the input sample into a list of OBUs.

Expects the AV1 sample format specified by the AV1 Codec ISO Media File Format Binding. That is, each OBU has the obu_has_size_field set to 1 except for the last OBU in the sample, for which obu_has_size_field may be set to 0.

Parameters
ByteBuffer sample

The sample data.
Returns
List<ObuParser.Obu>

The list of OBUs contained within the sample data.
