示例1: recorderEncoderLoop

* Reads bytes from the given recorder and encodes them with the given encoder.
* Uses the (deprecated) Synchronous Processing using Buffer Arrays.
* <p/>
* Encoders (or codecs that generate compressed data) will create and return the codec specific
* data before any valid output buffer in output buffers marked with the codec-config flag.
* Buffers containing codec-specific-data have no meaningful timestamps.
