The doxy expresses what a function does, not what it should do.

Avoid the need to implement slice direction detection code, thus
reducing code duplication.

The assumption depends on the corresponding assumption done by
sws_scale() and by the scale filter.

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.

avfilter_default_get_video_buffer() if the get_video_buffer() callback
is not defined in a filter.
Libavfilter filters author have to explicitely define the
get_video_buffer() callback if they want the buffer to be requested to
the filter following in the filterchain.
See the thread:
"[FFmpeg-devel] [PATCH] Make avfilter_get_video_buffer() use
default_get_video_buffer if callback not defined".

Originally committed as revision 20299 to svn://svn.ffmpeg.org/ffmpeg/trunk
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.

"[PATCH] Implement recusive avfilter_get_video_buffer()".

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

This can now handle filters which are added to graphs out of order,
including auto-inserted scale filters. As an added bonus, it can
now detect circular filter chains which wouldn't work anyway.

This should make it easier to know what can be done to a buffer once
it's been passed to your filter without falling back to copying it "just
to be safe".

This makes it possible to change filter callbacks (eg. to a SIMD version
on supported processors). It also allows filters to change their own
input and output pads.
