Overview

Callback from the encoder.

Summary

Constructors
protectedWriterCallback()

Methods
public abstract voidonComplete(EncoderBase encoder)

Called when encoding reached the end of stream without error.

public voidonDrainOutputBuffer(EncoderBase encoder, java.nio.ByteBuffer byteBuffer)

Upon receiving an output buffer from the encoder (which is one image when grid is not used, or one tile if grid is used), add that sample to the muxer.

public abstract voidonError(EncoderBase encoder, CodecException e)

Called when encoding hits an error.

public voidonOutputFormatChanged(EncoderBase encoder, MediaFormat format)

Upon receiving output format from the encoder, add the requested number of image tracks to the muxer and start the muxer.
