This avoid recalculating it and in case w/h changed avoids crashes.

Any volunteers to port the pp and spp filters from libmpcodec?

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

The new name is more meaningful in that context.

Deprecate functions:
avfilter_fill_frame_from_buffer_ref
avfilter_fill_frame_from_audio_buffer_ref
avfilter_fill_frame_from_video_buffer_ref

and schedule to drop them at the next API major bump.

The function avfilter_copy_buf_props() should be used instead.

The code in avfilter_copy_buf_props() is more generic, allow code
factorization.

Use av_frame_* accessors for the newly added fields in AVFrame (for which
we are supposed to use such accessors), and group the istructions
accordingly.

The function will abort through an assert if the source is not defined,
or if the internal state of the source is inconsistent (e.g. type = AUDIO
&& !src->audio).

avcodec.c is where it is defined the lavc/lavfi interface code, so seems
a more adequate location (and doesn't force the inclusion of
libavcodec/avcodec.h where it is not required).

The new location is more suited, as it is where the lavfi/lavc glue is
defined.

This fixes issues with AVFrame w/h being wrong in some cases

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Simplify passing AVFrame data to av_vsrc_buffer_add_video_buffer_ref().

avfilter_copy_frame_props() avoids code duplication and increases
robustness.

The added files libavfilter/avcodec.[ch] are used for containing
utilities useful for gluing togheter libavfilter and libavcodec.

The new name is shorter and consistent with the FFmpeg style.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Otherwise doxygen complains about ambiguous filenames when files exist
under the same name in different subdirectories.

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_".
