Constructor Detail

H264Reader

public H264Reader(com.google.android.exoplayer2.extractor.ts.SeiReader seiReader,
                  boolean allowNonIdrKeyframes,
                  boolean detectAccessUnits)

Parameters:

seiReader - An SEI reader for consuming closed caption channels.

allowNonIdrKeyframes - Whether to treat samples consisting of non-IDR I slices as synchronization samples (key-frames).

detectAccessUnits - Whether to split the input stream into access units (samples) based on slice headers. Pass false if the stream contains access unit delimiters (AUDs).

Method Detail

seek

public void seek()

Description copied from interface: ElementaryStreamReader

Notifies the reader that a seek has occurred.

Specified by:

seek in interface ElementaryStreamReader

createTracks

Description copied from interface: ElementaryStreamReader

Initializes the reader by providing outputs and ids for the tracks.

Specified by:

createTracks in interface ElementaryStreamReader

Parameters:

extractorOutput - The ExtractorOutput that receives the extracted data.

idGenerator - A PesReader.TrackIdGenerator that generates unique track ids for the TrackOutputs.
