Note that VoE file playing functionality is going to be remove really soon. What
is the use case of the changes in this CL?

I use it for a little project by myself. So I don't mind not checking in voe
related changes. But if future changes need FilePlayer as a reference, it is
good to fix it.

-  enum { MAX_AUDIO_BUFFER_IN_SAMPLES = 60 * 32 };
+  // The largest decoded frame size in samples (120ms with 48kHz sample rate).
+  enum { MAX_AUDIO_BUFFER_IN_SAMPLES = 120 * 48 };
   enum { MAX_AUDIO_BUFFER_IN_BYTES = MAX_AUDIO_BUFFER_IN_SAMPLES * 2 };
 
   // Note: will return NULL for unsupported formats.
