link rather than avfilter_default_get_video_buffer().
This is required as the buffer requested may be greater than the
buffer allocated locally by avfilter_default_get_video_buffer(), for
example if in filterchain there is a pad filter (like in "fifo,pad").
In that case the pad filter will try to write beyond the data of the
allocated buffer, resulting in a crash.

The plural form is preferred as it is more consistent with the other functions:
av_fill_image_linesizes()
av_fill_image_pointers()
and looks semantically more correct as it fills an array of elements.

To display the other planes is usually not useful and add noise to the
output.

This is required to make AVFilterBufferRef able to contain also audio
data, required by audio filtering integration.

AVFilterContext *avfilter_open(AVFilter *filter, const char *inst_name);
to:
int avfilter_open(AVFilterContext **filter_ctx, AVFilter *filter, const char *inst_name);
This way it is possible to propagate an error code telling the reason
of the failure.

Define a new struct AVFilterBufferRefVideoProps and add a type field
to AVFilterBufferRef.
Video specific properties in AVFilterBufferRefVideoProps are now
referred to by *video pointer in AVFilterBufferRef.

AVFilterLink.srcpic -> AVFilterLink.src_buf
AVFilterLink.cur_pic -> AVFilterLink.cur_buf
AVFilterLink.outpic -> AVFilterLink.out_buf
The new names are more generic and more consistent, since the struct
they contain, which was named AVFilterPicRef, has been renamed to
AVFilterBufferRef.

They have been renamed to allow sharing with audio.

The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.

The error was being caused by the previous patch which resized
AVFilterBuffer's data and linesize arrays to 8.

libavcore/imgutils.c rather than ff_fill_linesize() and
ff_fill_pointer().
Also remove a dependency on libavcodec.

Although with several limitations, lavfi can be compiled and used
without the scale filter.

in favor of the newly added corresponding functions
av_parse_video_size() and av_parse_video_rate() defined in
libavcore/parseutils.h.
This change also adds a linking-time dependency of libavcodec and of
libavfilter on libavcore.
Originally committed as revision 24518 to svn://svn.ffmpeg.org/ffmpeg/trunk
This is needed to make the libavfilter framework work with audio
filters.
In particular add a type field to AVFilterLink, change the field types:
enum PixelFormat format -> int format in AVFilterBuffer
enum PixelFormat *formats -> int *formats in AVFilterFormats
enum PixelFormat *format -> int format in AVFilterLink
and change the function signatures:
AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
AVFilterFormats *avfilter_make_format_list(const int *fmts);
int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
int avfilter_add_format(AVFilterFormats **avff, int fmt);
AVFilterFormats *avfilter_all_colorspaces(void); ->
AVFilterFormats *avfilter_all_formats(enum AVMediaType type);
This change breaks libavfilter API/ABI.
