3db407038e lavfi: use const for AVFilterPad declarations in all filters. 2012-07-21 16:31:15 -07:00

07bad27810 lavfi: unref AVFilterLink.cur_buf in ff_end_frame().
This reduces code duplication and prevents stale pointers from remaining
on the link.

a5e8c41c28 lavfi: remove 'opaque' parameter from AVFilter.init()
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

9d0bfc5052 lavfi: make AVFilterPad opaque after two major bumps.
It will allow adding new fields to it without ABI breaks.

803391f719 lavfi: remove request/poll and drawing functions from public API on next bump
They are only useful inside filters and we don't allow user filters for
now.

c04c533f62 lavfi: remove avfilter_null_* from public API on next bump.
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

38d5533228 pixdesc: mark pseudopaletted formats with a special flag.
This makes it possible to dintinguish them from PAL8.

Fixes an invalid write in avpicture_layout().

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

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.

to AVFilterBufferRef.

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