The previous default value 0x0 was not good, since it is not even
valid.

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.

The feature was dropped after the filter was partially rewritten and
recommitted.

Signed-off-by: Anton Khirnov <anton@khirnov.net>

The list type was changed to int64_t to be able to hold
channel layouts.

avfilter_make_format_list() still takes a int32_t array and converts
it to int64_t. A new function, avfilter_make_format64_list, that
takes int64_t arrays has been added.

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 *).

Add a missing space between vsink_buffer.h and vsrc_buffer.h.
1000l.

Also add the public interface libavfilter/vsink_buffer.h.

Avoid timescale conversion, simplify.

This filter is a simple wrapper around the LUT filter.

-1 is more correct than 0, as the position in the file is undefined.

Also remove outdated reference to color in vf_pad.c.

Fix a crash occurring when open_inputs is NULL and *open_inputs is
checked, the crash was introduced by the recent avfilter_graph_parse()
syntax change.

In particular, fix graph2dot crash.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Make it returns the list of open inputs and outputs, so it can be
reused by applications.

Breaks API/ABI.

Require "void *" rather than "AVClass *" for the log context type.

This fixes a double-free crash if lists are the same due to the two
merge_ref() calls at the end of the (useless) merging that happens.

Use avfilter_get_audio_buffer_ref_from_arrays() in
avfilter_default_get_audio_buffer(), simplify.

Remove AVFilterBufferRefAudioProps.size, and use nb_samples in
avfilter_get_audio_buffer() and avfilter_default_get_audio_buffer() in
place of size.

This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.
