FFAudioFormat

public FFAudioFormat(int codecId,
                     float sampleRate,
                     int sampleSize,
                     int channels,

                     Boolean vbr,
                     boolean encrypted)

Creates a new FFAudioFormat from the given codec and format parameters.

Parameters:

codecId - FFmpeg AVCodecID value

sampleRate - sample rate in Hz

sampleSize - bits per sample, or AudioSystem.NOT_SPECIFIED

channels - channel count, or AudioSystem.NOT_SPECIFIED

frameSize - frame size in bytes, or AudioSystem.NOT_SPECIFIED

frameRate - frame rate in frames per second, or AudioSystem.NOT_SPECIFIED

bigEndian - true if samples are big-endian

bitRate - bit rate in bits per second, or 0 if unknown

vbr - true if variable bit rate, false if CBR, or null if unknown

encrypted - true if the stream is DRM-protected
