/* benski> some of this is TODO as of 25-Jan-2012
|
||
|
|
We want to have several ways to create a decoder
|
||
|
|
1) Simple method. Create a decoder of the desired style (callback, pull, packet). api_decode will convert between styles if necessary
|
||
|
|
2) Constraint method: Non-zero values for nsaudio::Parameters members are treated as requirements and api_decode will convert. Flags might indicate that sample rate or channels is a "maximum" rather than a strict requirement
|
||
|
|
3) Multiple nsaudio::Parameters values. Used if you are a little more flexible in the data format, e.g. if you can handle 16bit audio or floating point
