5a9dd3de63 Make avfilter_start_frame() invoke avfilter_get_video_buffer() on the 
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.

e34433612f Rename av_fill_image_max_pixstep() to av_fill_image_max_pixsteps(). 
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.

bdab614be8 Generalize pixel format enum fields to int formats. 
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.

Create a new static array containing pointers to the AVFilter
definitions, so that the non-constant next filter in the AVFilter
struct is not anymore required and the AVFilter definitions may be
stored in shareable memory.

Also change the signature for avfilter_register(), make it return an
int since it may fail if there is not enough space in the static array
for the registered filters.

0eb4ff9e37 Make avfilter_get_video_buffer() recursive. 
When called on a link with a filter whose destination pad has not a
get_video_buffer callback defined, it will call
avfilter_get_video_buffer() on the first output link of the
destination filer, rather than use avfilter_default_get_buffer(), so
the video buffer can be allocated forward in the filterchain.

Also add the w and h parameters to avfilter_get_video_buffer(), as the
minimum width and height requested by each filter in the filterchain
may change, this allows for example a memcpy-less pad filter.

This change breaks API / ABI backward compatibility.

directory have to be prefixed by "FFMPEG_".
