[FFmpeg-cvslog] lavfi/af_volumedetect: print stats in uninit().

[Nicolas George]

ffmpeg | branch: master | Nicolas George <nicolas.george at normalesup.org> | Wed Oct 17 19:42:20 2012 +0200| [48ec8b25a7deb1a12cd06a064d2bc16440bcbe92] | committer: Nicolas George

lavfi/af_volumedetect: print stats in uninit().

If the stats are printed when request_frame on the input
returns EOF, then they are never printed if the filter is
not flushed, in particular when using the -t ffmpeg option.

Fix trac ticket #1727.
