private org.bytedeco.javacpp.BytePointer allocatedExtraDataPointer

status

private String status

keyFrameReceived

boolean keyFrameReceived

preparedIO

private AtomicBoolean preparedIO

cancelOpenIO

private AtomicBoolean cancelOpenIO

muxerType

public String muxerType

Constructor Details

EndpointMuxer

public EndpointMuxer(String url,
 io.vertx.core.Vertx vertx)

Method Details

getMuxerType

public String getMuxerType()

parseEndpointURL

void parseEndpointURL(String url)

getOutputURL

public String getOutputURL()

Overrides:

getOutputURL in class Muxer

addStream

public boolean addStream(org.bytedeco.ffmpeg.avcodec.AVCodec codec,
 org.bytedeco.ffmpeg.avcodec.AVCodecContext codecContext,
 int streamIndex)

Add a new stream with this codec, codecContext and stream Index parameters. After adding streams, need to call prepareIO() This method is called by encoder. After encoder is opened, it adds codec context to the muxer

Overrides:

addStream in class Muxer

Returns:

setStatusListener

public void setStatusListener(IEndpointStatusListener listener)

getOutputFormatContext

public org.bytedeco.ffmpeg.avformat.AVFormatContext getOutputFormatContext()

Specified by:

getOutputFormatContext in class Muxer

setStatus

public void setStatus(String status)

getStatus

public String getStatus()

prepareIO

public boolean prepareIO()

This function may be called by multiple encoders. Make sure that it is called once. See the sample implementations how it is being protected Implement this function with synchronized keyword as the subclass

Overrides:

prepareIO in class Muxer

Returns:

writeHeader

public boolean writeHeader()

If the broadcast is stopped while the muxer is writing the header it cannot complete writing the header Then writeTrailer causes crash because of memory problem. We need to control if header is written before trying to write Trailer and synchronize them.

Overrides:

writeHeader in class Muxer

writeTrailer

public void writeTrailer()

This function may be called by multiple encoders. Make sure that it is called once. See the sample implementations how it is being protected Implement this function with synchronized keyword as the subclass Look at the comments writeHeader

Overrides:

writeTrailer in class Muxer

clearResource

public void clearResource()

Overrides:

clearResource in class Muxer

exitIfCancelled

private boolean exitIfCancelled()

addVideoStream

public boolean addVideoStream(int width,
 int height,
 org.bytedeco.ffmpeg.avutil.AVRational timebase,
 int codecId,
 int streamIndex,
 boolean isAVC,
 org.bytedeco.ffmpeg.avcodec.AVCodecParameters codecpar)

Add video stream to the muxer with direct parameters. This method is called when there is a WebRTC ingest and there is no adaptive streaming

Overrides:

addVideoStream in class Muxer

Parameters:

width - , video width

height - , video height

codecId - , codec id of the stream

streamIndex - , stream index

isAVC - , true if packets are in AVC format, false if in annexb format

Returns:

true if successful, false if failed

writePacket

public void writePacket(org.bytedeco.ffmpeg.avcodec.AVPacket pkt,
 org.bytedeco.ffmpeg.avutil.AVRational inputTimebase,
 org.bytedeco.ffmpeg.avutil.AVRational outputTimebase,
 int codecType)

Description copied from class: Muxer

All other writePacket functions call this function to make the job

Overrides:

writePacket in class Muxer

Parameters:

pkt - Content of the data in AVPacket class

inputTimebase - input time base is required to calculate the correct dts and pts values for the container

outputTimebase - output time base is required to calculate the correct dts and pts values for the container

writeFrameInternal

 org.bytedeco.ffmpeg.avutil.AVRational inputTimebase,
 org.bytedeco.ffmpeg.avutil.AVRational outputTimebase,
 org.bytedeco.ffmpeg.avformat.AVFormatContext context,
 int codecType)

avWriteFrame

public void avWriteFrame(org.bytedeco.ffmpeg.avcodec.AVPacket pkt,
 org.bytedeco.ffmpeg.avformat.AVFormatContext context)

writeVideoBuffer

public void writeVideoBuffer(ByteBuffer encodedVideoFrame,
 long dts,
 int frameRotation,
 int streamIndex,
 boolean isKeyFrame,
 long firstFrameTimeStamp,
 long pts)

Overrides:

writeVideoBuffer in class Muxer

isCodecSupported

public boolean isCodecSupported(int codecId)

Specified by:

isCodecSupported in class Muxer
