public Range<Integer> getComplexityRange ()
Returns the supported range of encoder complexity values.
Some codecs may support multiple complexity levels, where higher complexity values use more encoder tools (e.g. perform more intensive calculations) to improve the quality or the compression ratio. Use a lower value to save power and/or time.

Range<Integer> |
public Range<Integer> getQualityRange ()
Returns the supported range of quality values. Quality is implementation-specific. As a general rule, a higher quality setting results in a better image quality and a lower compression ratio.
