readFlacFrame

public static int readFlacFrame(java.io.InputStream inputStream,
                                BitStreamReader reader,
                                FlacStreamInfo streamInfo,
                                int[][] rawSampleBuffers,
                                short[][] sampleBuffers,
                                int[] temporaryBuffer)
                         throws java.io.IOException

Reads one frame, returning the number of samples written to sampleBuffers. A return value of 0 indicates that EOF was reached in the frame, which happens when the track ends.

Parameters:

inputStream - Input stream for reading the track

reader - Bit stream reader for the same underlying stream as inputStream

streamInfo - Global stream information

rawSampleBuffers - Intermediate sample decoding buffers. FlacStreamInfo#channelCount integer buffers of size at least FlacStreamInfo#maximumBlockSize.

sampleBuffers - The sample buffers where the final decoding result is written to. FlacStreamInfo#channelCount short buffers of size at least FlacStreamInfo#maximumBlockSize.

temporaryBuffer - Temporary working buffer of size at least TEMPORARY_BUFFER_SIZE. No state is held in this between separate calls.

Returns:

The number of samples read, zero on EOF

Throws:

java.io.IOException - On read error
