dc46692ded ffmpeg: fix setting codecs for demuxers. 
Bug introduced by:
commit e3bf4e292c
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]

2c6cf13940 wavpack: Reset internal state on corrupted blocks 
wavpack_decode_block() supposes that it is called back with the exact
same buffer unless it has returned with an error. With multi-channels
files, wavpack_decode_frame() was breaking this assumption.

a85996d834 libstagefright: start decode_thread() only after decode_frame() is called at least once. 
This prevents the situation where EOS is passed as the first frame to the
h/w decoder and thus avoids a potential crash.

14c21c1ff5 H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock 
This allows concurrent decoding of the last field/frame, rather than
only the last slice, of data packets with multiple NAL units packed
together.

This will fix the slowdown reported in e.g. bug 52.
