 String s3FolderPath)

Method Details

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

prepareAudioOutStream

protected boolean prepareAudioOutStream(org.bytedeco.ffmpeg.avformat.AVStream inStream,
 org.bytedeco.ffmpeg.avformat.AVStream outStream)

Overrides:

prepareAudioOutStream in class RecordMuxer

remux

public static void remux(String srcFile,
 String dstFile,
 int rotation)

Parameters:

srcFile -

dstFile -

rotation - clockwise rotation

finalizeRecordFile

protected void finalizeRecordFile(File file)
                           throws IOException

Overrides:

finalizeRecordFile in class RecordMuxer

Throws:

IOException

clearResource

public void clearResource()

Overrides:

clearResource in class Muxer

writeAudioFrame

protected void writeAudioFrame(org.bytedeco.ffmpeg.avcodec.AVPacket pkt,
 org.bytedeco.ffmpeg.avutil.AVRational inputTimebase,
 org.bytedeco.ffmpeg.avutil.AVRational outputTimebase,
 org.bytedeco.ffmpeg.avformat.AVFormatContext context,
 long dts)

Overrides:

writeAudioFrame in class Muxer
