Method Detail

getConfig

public EncodingConfig getConfig()

prepare

public void prepare(EncodingConfig config)

setEventBus

public void setEventBus(EventBus eventBus)

getOutputPath

public java.lang.String getOutputPath()

Returns the absolute output path.

e.g /sdcard/app/uuid/index.m3u8

Returns:

addTrack

public int addTrack(android.media.MediaFormat trackFormat)

Adds the specified track and returns the track index

Parameters:

trackFormat - MediaFormat of the track to add. Gotten from MediaCodec#dequeueOutputBuffer when returned status is INFO_OUTPUT_FORMAT_CHANGED

Returns:

index of track in output file

onEncoderReleased

public void onEncoderReleased(int trackIndex)

Called by the hosting Encoder to notify the Muxer that it should no longer assume the Encoder resources are available.

release

public void release()

writeSampleData

public void writeSampleData(android.media.MediaCodec encoder,
                   int trackIndex,
                   int bufferIndex,
                   java.nio.ByteBuffer encodedData,
                   android.media.MediaCodec.BufferInfo bufferInfo)

Write the MediaCodec output buffer. This method must be overridden by subclasses to release encodedData, transferring ownership back to encoder, by calling encoder.releaseOutputBuffer(bufferIndex, false);

Parameters:

trackIndex -

encodedData -

bufferInfo -

allTracksFinished

protected boolean allTracksFinished()

allTracksAdded

protected boolean allTracksAdded()

signalEndOfTrack

public void signalEndOfTrack()

Muxer will call this itself if it detects BUFFER_FLAG_END_OF_STREAM in writeSampleData.

formatRequiresADTS

protected boolean formatRequiresADTS()

Does this Muxer's format require AAC ADTS headers? see http://wiki.multimedia.cx/index.php?title=ADTS

Returns:

formatRequiresBuffering

protected boolean formatRequiresBuffering()

Does this Muxer's format require copying and buffering encoder output buffers. Generally speaking, is the output a Socket or File?

Returns:

getNextRelativePts

protected long getNextRelativePts(long absPts,
                      int trackIndex)

Return a relative pts given an absolute pts and trackIndex.

This method advances the state of the Muxer, and must only be called once per call to writeSampleData(android.media.MediaCodec, int, int, java.nio.ByteBuffer, android.media.MediaCodec.BufferInfo).
