Method Detail

configureAVCodecContext

protected void configureAVCodecContext(long avctx,
                                       javax.media.format.AudioFormat format)

Configures the AVCodecContext initialized in AbstractFFmpegAudioCodec.doOpen() prior to invoking one of the FFmpeg functions in the avcodec_open family. Allows extenders to override and provide additional, optional configuration.

Overrides:

configureAVCodecContext in class FFmpegAudioEncoder

Parameters:

avctx - the AVCodecContext to configure

format - the AudioFormat with which avctx is being configured

doProcess

protected int doProcess(javax.media.Buffer inBuf,
                        javax.media.Buffer outBuf)

Overrides:

doProcess in class FFmpegAudioEncoder

setOutputFormat

public javax.media.Format setOutputFormat(javax.media.Format format)

Additionally, determines whether this JNIEncoder is to perform RTP packetization.

Specified by:

setOutputFormat in interface javax.media.Codec

Overrides:

setOutputFormat in class AbstractCodec2

getOutputFormat

public javax.media.Format getOutputFormat()

Gets the Format of the media output by this Codec.

Overrides:

getOutputFormat in class net.sf.fmj.media.AbstractCodec

Returns:

the Format of the media output by this Codec
