                  throws UnsupportedAudioFileException

Creates a new FFAudioFileFormat. Called from native code in FFAudioFileReader.c.

Parameters:

url - URL string of the audio source, or null

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

frameLength - total frame count, or AudioSystem.NOT_SPECIFIED

bigEndian - true if samples are big-endian

durationInMicroSeconds - duration in microseconds, or 0 if unknown

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

Throws:

UnsupportedAudioFileException - if the URL extension is not recognised
