Stefano Sabatini 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.

Stefano Sabatini 84c0386960 Change avfilter_open() signature, from:
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.

S.N. Hemanth Meenakshisundaram cc80caff52 Separate video specific BufferRef properties into VideoProps.
Define a new struct AVFilterBufferRefVideoProps and add a type field

Video specific properties in AVFilterBufferRefVideoProps are now
referred to by *video pointer in AVFilterBufferRef.

S.N. Hemanth Meenakshisundaram 5d4890d73d Rename fields:
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.

S.N. Hemanth Meenakshisundaram 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.

Stefano Sabatini 5bb5c1dc86 Add AVFilterPicRef.pos field and make libavfilter propagate stream
byte position information, as stored in the pkt.pos, through the

Note that the pos field is added *non* at the end of the
AVFilterPicRef struct, thus breaking ABI compatibility, which is
allowed as the API is still considered non-stable.
