ffmpeg: fix setting codecs for demuxers. · dc46692d

Michael Niedermayer authored Oct 08, 2011

Bug introduced by:
commit e3bf4e29
Author: Anton Khirnov <anton@khirnov.net>
Date:   Tue Aug 30 04:10:54 2011 +0200

    ffmpeg: replace -vcodec/-acodec/-scodec with a better system.

    The new option doesn't depend on its placement wrt -new* options (which
    don't exist anymore) and works in a similar way as per-stream AVOptions.

    -[vas]codec remain as aliases to -codec:[vas]

wavpack_decode_block() supposes that it is called back with the exact
same buffer unless it has returned with an error. With multi-channels
