191ee4aefb avfilter/af_ladspa: set output channel layout for passthrough case 
For cases when plugin does not return any samples we just return
input samples. Previously channel layout for outlink was not set.
Set it explicitly instead.

The 32-bit integer accumulator in MSE computation can overflow for 8-bit frame data.
(e.g., for 1080p white frame compared to a black frame can give sum of 255*255*1080*1920 > 2^32).

3dfc5f551f avfilter: avoid testing float == 0 
This fixes the hypothetical case of rounding errors causing
incorrect values to be used.
We do not use *_EPSILON, because non trivial expressions can contain
errors larger than that making a zero equality test with *_EPSILON
unreliable.

53102fa2f0 Revert "avfilter/vf_noise: dont corrupt the picture outside width x height" 
This reverts commit 51dab60c7b.

this fixed nothing, and was just the result of assuming that the
variable named linesize was the linesize. Its not, its the width
in bytes which was already correct.

cb8f70c96e vf_fps: use double constants for default/min/max for start_time 
When using AV_NOPTS_VALUE (which expands to INT64_C(0x8000000000000000))
as union initializer for a double field, the c99 converter needs to
interpret this constant when filling the union initializer, and it is
interpreted as a positive value.

When converting AV_NOPTS_VALUE to a double, MSVC 2010 ends up with
the same positive value as the c99 converter, while MSVC 2012 gets
a negative value.

This results in an infite loop in various FATE tests on MSVC 2012.

4e10d87f38 lavfi/delogo: band width must be at least 1 
We need at least one pixel around the logo to use as known points to
interpolate from. So properly declare the band/t attribute has having
a minimum value of 1.

72abce3c46 lavfi/delogo: option show shouldn't affect band 
Options "show" and "band" are unrelated and should thus be
independent. However, setting "show" to 1 currently resets "band" to
its default value of 4. While this is documented, this still
surprising and confusing IMHO.

Change this behavior and make "show" and "band" independent from each
other. Update the documentation accordingly.

4e8d6b315c lavfi/delogo: remember left and right samples when interpolating 
The left and right samples are the same for the whole line, so store
their values and don't recompute them for every iteration of "y".

This simple optimization results in a speed improvement between 15%
and 20% in my tests (depending on the logo geometry.)

Result is obviously the same.
