MediaOutput

public MediaOutput()

Method Details

create

public boolean create(String file,
 String format)

Create output file.

Parameters:

file - = filename

format - = media container (see MediaCoder.AV_FORMAT_ID...)

create

public boolean create(MediaIO io,
 String format)

Create output media via MediaIO.

Parameters:

io - = Media IO interface

format - = media container (see MediaCoder.AV_FORMAT_ID...)

addVideoStream

public boolean addVideoStream(CodecInfo info)

Adds a video stream to output. All media streams must be added before calling write()

Parameters:

info - .width/height = video dimension info.fps = frames per second info.keyFrameInterval = key frame interval info.video_codec = video codec (0=default for format) info.video_bit_rate = video bit rate (default = 1Mb/s)

Returns:

true if successful info.stream = stream index info.video_codec = selected codec

addAudioStream

public boolean addAudioStream(CodecInfo info)

Adds an audio stream to output. All media streams must be added before calling write()

Parameters:

info - .chs = audio channels info.freq = audio sample rate info.audio_codec = audio codec (0=default for format) info.audio_bit_rate = audio bit rate (default = 128Kb/s)

Returns:

true is successful info.stream = stream index info.audio_codec = selected codec

createVideoEncoder

public MediaVideoEncoder createVideoEncoder(CodecInfo info)

Creates a video stream by invoking addVideoStream() and returns a video encoder for new stream.

createAudioEncoder

public MediaAudioEncoder createAudioEncoder(CodecInfo info)

Creates an audio stream by invoke addAudioStream() and returns an audio encoder for new stream.

close

public boolean close()

Closes media file and frees resources.

writePacket

public boolean writePacket(Packet packet)
