Constructor Detail

public EncodingConfigurationImpl()

Constructor. Loads the default preferences.

Method Detail

setEncodingPreference

protected void setEncodingPreference(String encoding,
                                     double clockRate,
                                     int pref)

Sets pref as the preference associated with encoding. Use this method for both audio and video encodings and don't worry if preferences are equal since we rarely need to compare prefs of video encodings to those of audio encodings.

Specified by:

setEncodingPreference in class EncodingConfiguration

Parameters:

encoding - the SDP int of the encoding whose pref we're setting.

clockRate - clock rate

pref - a positive int indicating the preference for that encoding.

getAllEncodings

public MediaFormat[] getAllEncodings(org.jitsi.utils.MediaType type)

Returns all the available encodings for a specific MediaType. This includes disabled ones (ones with priority 0).

Specified by:

getAllEncodings in class EncodingConfiguration

Parameters:

type - the MediaType we would like to know the available encodings of

Returns:

array of MediaFormat supported for the MediaType

compareEncodingPreferences

protected int compareEncodingPreferences(MediaFormat enc1,
                                         MediaFormat enc2)

Compares the two formats for order. Returns a negative integer, zero, or a positive integer as the first format has been assigned a preference higher, equal to, or greater than the one of the second.

Specified by:

compareEncodingPreferences in class EncodingConfiguration

Parameters:

enc1 - the first format to compare for preference.

enc2 - the second format to compare for preference

Returns:

a negative integer, zero, or a positive integer as the first format has been assigned a preference higher, equal to, or greater than the one of the second
