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

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Also remove outdated reference to color in vf_pad.c.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.

Deprecate the last remaining member of AVFormatParameters.

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.

Avoids warning about discarding qualifiers in avcodec.c

Allow to free the buffers cached in each AVFilterLink pool.
Fix leak.

Propagate av_vsrc_buffer_add_video_buffer_ref() error code rather than
return 0.

Clarify code layout.

The comment is meant to be about the align parameter.

Adopt K&R style for overall consistency/readability.

Also include an older fix for vf_smartblur which was essentially
broken due to reading the threshold value wrongly.

Since this is only a compilation check (the actual function used is
selected at runtime) and HAVE_SSE indicates that we can also compile
SSE2 code, this is correct.

Fixes compiler warning about incompatible types in sws_scale call.
