91d1c741bf Create a set of null callback functions.
These are useful for filters which don't modify the image data.

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

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.

1250fcc862 avfilter: make avfilter_default_free_video_buffer() static
This function is not referenced outside this file and has no
prototype.  Feel free to flame if this is wrong.

b5eab66e9f Make avfilter_default_start_frame() request a buffer with the same
size of the output link of the destination filter, rather than of the
size of the input link.
In particular this fixes a crash in the rotate filter.

a13a543797 Add a slice_dir parameter to avfilter_draw_slice().
Avoid the need to implement slice direction detection code, thus
reducing code duplication.

See the thread:
"[FFmpeg-devel] [PATCH] Add a slice_dir parameter to avfilter_start_frame()".

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.

See the thread:
"[PATCH] Implement recusive avfilter_get_video_buffer()".

459821c533 Rework link property configuration system.
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.

4d62c9d377 Track the permissions that have been given out to each picture.
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".
