Fields Summary

Constructors Summary

Methods Summary
public float	getPreferredQuality() Returns the default quality recommended for decoding or encoding. return the preferred decoding or encoding quality.
public float	getQuality() Returns the current value of the decoding or encoding quality parameter. return the current decoding or encoding quality.
public boolean	isTemporalSpatialTradeoffSupported() Returns if the encoder can increase frame rate with reduced resolution and vica-versa. return if the encoder can increase frame rate with reduced resolution and vica-versa.
public float	setQuality(float newQuality) Set the quality for the decoding or encoding. This value may have different effects depending on the type of compression. A higher quality setting will result in better quality of the resulting outputb, e.g. better image quality for video. There is usually a tradeoff between CPU usage and the quality: higher quality requires higher CPU usage. This value is only a hint and the codec can choose to ignore it. The actual value that was set is returned. It should be in the range of 0.0 to 1.0. param newQuality the decoding or encoding quality. return the quality that is actually set.
