Author: Kostya Shishkov <[email protected]> Committer: Anton Khirnov <[email protected]> Date: Fri Sep 2 11:37:39 2011 +0200 wavpack: use context reset in appropriate places This fixes improper flushing in the cases when the same frame is decoded in several iterations (for being too large to fit into output buffer) and flush is called mid-decoding and it also resets context in case of decoding errors.
