* In the AVCodecDecoder, use the audio format of the original input format, 

but specify it to 16bits/sample if it's still a wildcard. Make sure to
  allocate the scrub buffer with the correct sample size (was hardcoded to 2
  bytes per sample).
* In the AVFormatReader, specify the sample format for B_MEDIA_ENCODED_AUDIO.
