dcce09d64b dxva: Add ability to enable workaround for older ATI cards 
The workaround needs to be enabled per PCI ID which cannot be detected inside
libavcodec. So add a flag to manually enable the alternate behavior.

bf00a73ace dca: clear inactive subbands only once in qmf_32_subbands() 
Writing zeros to the high entries in the array need only be

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.

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 *).

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.
