most of its life. When you queue an input buffer with the {@linkplain #BUFFER_FLAG_END_OF_STREAM
end-of-stream marker}, the codec transitions to the End-of-Stream sub-state. In this state the
codec no longer accepts further input buffers, but still generates output buffers until the
end-of-stream is reached on the output. You can move back to the Flushed sub-state at any time
while in the Executing state using {@link #flush}.
end-of-stream is reached on the output. For decoders, you can move back to the Flushed sub-state
at any time while in the Executing state using {@link #flush}.
<p class=note>
<strong>Note:</strong> Going back to Flushed state is only supported for decoders, and may not
work for encoders (the behavior is undefined).
<p>
Call {@link #stop} to return the codec to the Uninitialized state, whereupon it may be configured
again. When you are done using a codec, you must release it by calling {@link #release}.
