Method Detail

peekId3Metadata

@Nullable
public static[Metadata](../metadata/Metadata.html "class in com.google.android.exoplayer2.metadata")peekId3Metadata([ExtractorInput](ExtractorInput.html "interface in com.google.android.exoplayer2.extractor")input,
                                       boolean parseData)
                                throws[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")

Deprecated.

Peeks ID3 Data. Parameters:input - Input stream to peek the ID3 data from.parseData - Whether to parse the ID3 frames.Returns:The parsed ID3 data, or null if there is no such data or if parseData is false.Throws:IOException - If peeking from the input fails. In this case, there is no guarantee on the peek position.

checkAndPeekStreamMarker

public static boolean checkAndPeekStreamMarker([ExtractorInput](ExtractorInput.html "interface in com.google.android.exoplayer2.extractor")input)
                                        throws[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")

Deprecated.

Peeks the FLAC stream marker. Parameters:input - Input stream to peek the stream marker from.Returns:Whether the data peeked is the FLAC stream marker.Throws:IOException - If peeking from the input fails. In this case, the peek position is left unchanged.

readId3Metadata

@Nullable
public static[Metadata](../metadata/Metadata.html "class in com.google.android.exoplayer2.metadata")readId3Metadata([ExtractorInput](ExtractorInput.html "interface in com.google.android.exoplayer2.extractor")input,
                                       boolean parseData)
                                throws[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")

Deprecated.

Reads ID3 Data.

If no exception is thrown, the peek position of input is aligned with the read position.

Parameters:input - Input stream to read the ID3 data from.parseData - Whether to parse the ID3 frames.Returns:The parsed ID3 data, or null if there is no such data or if parseData is false.Throws:IOException - If reading from the input fails. In this case, the read position is left unchanged and there is no guarantee on the peek position.

readStreamMarker

public static void readStreamMarker([ExtractorInput](ExtractorInput.html "interface in com.google.android.exoplayer2.extractor")input)
                             throws[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")

Deprecated.

Reads the FLAC stream marker. Parameters:input - Input stream to read the stream marker from.Throws:ParserException - If an error occurs parsing the stream marker. In this case, the position of input is advanced by FlacConstants.STREAM_MARKER_SIZE bytes.IOException - If reading from the input fails. In this case, the position is left unchanged.

readMetadataBlock

public static boolean readMetadataBlock([ExtractorInput](ExtractorInput.html "interface in com.google.android.exoplayer2.extractor")input,[FlacMetadataReader.FlacStreamMetadataHolder](FlacMetadataReader.FlacStreamMetadataHolder.html "class in com.google.android.exoplayer2.extractor")metadataHolder)
                                 throws[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")

Deprecated.

Reads one FLAC metadata block.

If no exception is thrown, the peek position of input is aligned with the read position.

Parameters:input - Input stream to read the metadata block from (header included).metadataHolder - A holder for the metadata read. If the stream info block (which must be the first metadata block) is read, the holder contains a new instance representing the stream info data. If the block read is a Vorbis comment block or a picture block, the holder contains a copy of the existing stream metadata with the corresponding metadata added. Otherwise, the metadata in the holder is unchanged.Returns:Whether the block read is the last metadata block.Throws:IllegalArgumentException - If the block read is not a stream info block and the metadata in metadataHolder is null. In this case, the read position will be at the start of a metadata block and there is no guarantee on the peek position.IOException - If reading from the input fails. In this case, the read position will be at the start of a metadata block and there is no guarantee on the peek position.

readSeekTableMetadataBlock

public static[FlacStreamMetadata.SeekTable](FlacStreamMetadata.SeekTable.html "class in com.google.android.exoplayer2.extractor")readSeekTableMetadataBlock([ParsableByteArray](../util/ParsableByteArray.html "class in com.google.android.exoplayer2.util")data)

Deprecated.

Reads a FLAC seek table metadata block.

The position of data is moved to the byte following the seek table metadata block (placeholder points included).

Parameters:data - The array to read the data from, whose position must correspond to the seek table metadata block (header included).Returns:The seek table, without the placeholder points.

getFrameStartMarker

public static int getFrameStartMarker([ExtractorInput](ExtractorInput.html "interface in com.google.android.exoplayer2.extractor")input)
                               throws[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")

Deprecated.

Returns the frame start marker, consisting of the 2 first bytes of the first frame.

The read position of input is left unchanged and the peek position is aligned with the read position.

Parameters:input - Input stream to get the start marker from (starting from the read position).Returns:The frame start marker (which must be the same for all the frames in the stream).Throws:ParserException - If an error occurs parsing the frame start marker.IOException - If peeking from the input fails.
