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....

Implement libavfilter audio framework.

Cosmetics: put "{" on the same line of the "struct" keyword in struct
definitions.

More consistent with the rest of FFmpeg.

Apply misc cosmetics: add empty newlines for separating function
declarations and fix weird indent.

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...

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...

Rename AVFilterPicRef to AVFilterBufferRef.

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

Remove use of the deprecated function avcodec_check_dimensions(), use
av_check_image_size() instead.

Resize AVFilterBuffer to hold 8 planes/linesizes worth of data.

This is required for making AVFilterBuffer useful for storing audio
data.

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...

Move the AV_PERM_* flags definition outside the AVFilterPicRef
definition.

This way it is easier to reference them in other structures, for
example in the pending AVFilterSamplesRef struct.

Remove AVFilterBuffer w and h fields.

These fields are never used, and they do not seem to belong to
AVFilterBuffer anymore, now that it is now a media-independent
structure and these fields are video-related.

Create a set of null callback functions.

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

Avoid the use of the modal auxiliary "should" in the
AVFilter.query_formats doxy.
The doxy expresses what a function does, not what it should do.

Originally committed as revision 21075 to svn://svn.ffmpeg.org/ffmpeg/trunk

Change avfilter_add_colorspace() to make it accept **avff rather than
*avff, so that an AVFilterFormats struct is created and returned by
the function if *avff is NULL.

Make the function use more convenient.

Prefer "*FUNC_NAME(" over "* FUNC_NAME(" for XXX_configuration() and
XXX_license() functions, consistent with the rest of FFmpeg.

Make avfilter_get_video_buffer() use

Cosmetics: prefer "pix_fmts" over "pix_fmt" for the name of the

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...

Globally rename the header inclusion guard names.
