Constants

OBU_FRAME

const val OBU_FRAME = 6: Int

OBU type frame.

OBU_FRAME_HEADER

const val OBU_FRAME_HEADER = 3: Int

Public functions

split

java-static fun split(sample: ByteBuffer!): (Mutable)List<ObuParser.Obu!>!

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
sample: ByteBuffer!

The sample data.
Returns
(Mutable)List<ObuParser.Obu!>!

The list of OBUs contained within the sample data.
