Fixed the MD5 calculation error on some streams when both decoded output dumping and MD5 generation are on. (#607)

* * Fixed the MD5 calculation error on some streams when both decoded output dumping and MD5 generation are on.
 - The issue is with the final flushing of the remaining frames at the end of stream, where MD5 update is skipped when output dumping is on.

* * Minor format changes.
