A format conversion provider provides format conversion services
from one or more input formats to one or more output formats.
Converters include codecs, which encode and/or decode audio data,
as well as transcoders, etc. Format converters provide methods for
determining what conversions are supported and for obtaining an audio
stream from which converted data can be read.
The source format represents the format of the incoming
audio data, which will be converted.
The target format represents the format of the processed, converted
audio data. This is the format of the data that can be read from
the stream returned by one of the getAudioInputStream
methods.
Method from javax.sound.sampled.spi.FormatConversionProvider Detail: |
abstract public AudioInputStream getAudioInputStream(Encoding targetEncoding,
AudioInputStream sourceStream)
Obtains an audio input stream with the specified encoding from the given audio
input stream. |
abstract public AudioInputStream getAudioInputStream(AudioFormat targetFormat,
AudioInputStream sourceStream)
Obtains an audio input stream with the specified format from the given audio
input stream. |
abstract public Encoding[] getSourceEncodings()
Obtains the set of source format encodings from which format
conversion services are provided by this provider. |
abstract public Encoding[] getTargetEncodings()
Obtains the set of target format encodings to which format
conversion services are provided by this provider. |
abstract public Encoding[] getTargetEncodings(AudioFormat sourceFormat)
Obtains the set of target format encodings supported by the format converter
given a particular source format.
If no target format encodings are supported for this source format,
an array of length 0 is returned. |
abstract public AudioFormat[] getTargetFormats(Encoding targetEncoding,
AudioFormat sourceFormat)
Obtains the set of target formats with the encoding specified
supported by the format converter
If no target formats with the specified encoding are supported
for this source format, an array of length 0 is returned. |
public boolean isConversionSupported(Encoding targetEncoding,
AudioFormat sourceFormat) {
AudioFormat.Encoding targetEncodings[] = getTargetEncodings(sourceFormat);
for(int i=0; i< targetEncodings.length; i++) {
if( targetEncoding.equals( targetEncodings[i]) ) {
return true;
}
}
return false;
}
Indicates whether the format converter supports conversion to a particular encoding
from a particular format. |
public boolean isConversionSupported(AudioFormat targetFormat,
AudioFormat sourceFormat) {
AudioFormat targetFormats[] = getTargetFormats( targetFormat.getEncoding(), sourceFormat );
for(int i=0; i< targetFormats.length; i++) {
if( targetFormat.matches( targetFormats[i] ) ) {
return true;
}
}
return false;
}
Indicates whether the format converter supports conversion to one
particular format from another. |
public boolean isSourceEncodingSupported(Encoding sourceEncoding) {
AudioFormat.Encoding sourceEncodings[] = getSourceEncodings();
for(int i=0; i< sourceEncodings.length; i++) {
if( sourceEncoding.equals( sourceEncodings[i]) ) {
return true;
}
}
return false;
}
Indicates whether the format converter supports conversion from the
specified source format encoding. |
public boolean isTargetEncodingSupported(Encoding targetEncoding) {
AudioFormat.Encoding targetEncodings[] = getTargetEncodings();
for(int i=0; i< targetEncodings.length; i++) {
if( targetEncoding.equals( targetEncodings[i]) ) {
return true;
}
}
return false;
}
Indicates whether the format converter supports conversion to the
specified target format encoding. |
