<h1>Custom Decoder Engine</h1><p>
|
|
Demonstrates how to implement a custom decoder and use it with the high level API.
|
|
</p>
|
|
<p>
|
|
|
|
This is the same as the custom_decoder example, only it's used with the high level engine API
|
|
rather than the low level decoding API. You can use this to add support for Opus to your games, for
|
|
example (via libopus).</p>
