Method Detail

sdpToJmfEncoding

public static String sdpToJmfEncoding(String sdpEncodingStr)

Returns the String encoding, as specified in AudioFormat and VideoFormat, corresponding to the format specified in sdpFormatStr

Parameters:

sdpEncodingStr - the SDP index that we'd like to convert to a JMF format.

Returns:

one of the AudioFormat.XXX or VideoFormat.XXX format strings.

jmfToSdpEncoding

public static int jmfToSdpEncoding(String jmfEncoding)

Returns the SDP encoding number corresponding to jmfFormat.

Parameters:

jmfEncoding - one of the AudioFormat.XXX or VideoFormat.XXX format strings.

Returns:

the SDP index corresponding to jmfEncoding. Returns UNKNOWN_ENCODING if the encoding is not supported or jmfEncoding is null.

sdpToJmfEncodings

public static List<String> sdpToJmfEncodings(List<String> sdpEncodings)

Converts the list of sdpEncodings to a list of jmf compatible encoding strings as specified by the static vars in VideoFormat and AudioFormat.

Parameters:

sdpEncodings - a list containing strings representing SDP format codes.

Returns:

a list of strings representing JMF compatible encoding names.
