Mans Rullgard bf00a73ace dca: clear inactive subbands only once in qmf_32_subbands() 
Writing zeros to the high entries in the array need only be
done once as the cutoff position is constant throughout the
loop.

Stefano SabatiniandAnton Khirnov 1ee2014190 vf_unsharp: set default chroma size value to 5x5 
The previous default value 0x0 was not good, since it is not even
valid.

Stefano SabatiniandAnton Khirnov 998e8519ef vf_unsharp: fix out-of-buffer read 
In apply_unsharp(), when y is >= height, prevent out-of-buffer reading
from src, read from the last buffer line in src2 instead.

The check was implemented in the original unsharp libmpcodecs code and
lost in the port.

This also fixes output discrepancy between the two filters.

Stefano SabatiniandAnton Khirnov 0ec56d1144 lavfi: fix realloc size computation in avfilter_add_format() 
Replace sizeof((*avff)->formats)
with    sizeof(*(*avff)->formats)

as the size of the array element is given by the pointed element
rather than by its pointer.

In particular fix computation with the pending patch when
sizeof(int64_t) != sizeof(int64_t *).

Anton Khirnov d3c1d37a90 avconv: use different variables for decoded and filtered frame. 
Makes the code less obfuscated and fixes encoding one video stream to
several outputs.

Also use avcodec_alloc_frame() instead of allocating AVFrame on stack.

Breaks me_threshold in avconv, as motion vectors aren't passed through
lavfi. They could be copied manually, but I don't think this misfeature
is useful enough to justify ugly hacks.
