Change the syntax of the crop filter from x:y:w:h to w:h:x:y.

Slightly more intuitive and required by a pending changes for making
the filter parametric.

Implement ff_get_ref_perms_string() and use it for tracing.

Originally committed as revision 24900 to svn://svn.ffmpeg.org/ffmpeg/trunk

Make avfilter_start_frame() invoke avfilter_get_video_buffer() on the
link rather than avfilter_default_get_video_buffer().

This is required as the buffer requested may be greater than the
buffer allocated locally by avfilter_default_get_video_buffer(), for...

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....

Cosmetics: merge two lines in ff_dprintf_ref().

Rename ff_dprintf_picref() to ff_dprintf_ref().

The function is going to be used to represent also audio data.

Make ff_dprintf_picref() print video properties only if available.

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.

Fix the size of the data to be copied from an AVFilterBuffer to an
AVFilterBuffereRef in avfilter_default_get_video_buffer().

The error was being caused by the previous patch which resized
AVFilterBuffer's data and linesize arrays to 8.

Require libswscale only if the scale filter is used.

Although with several limitations, lavfi can be compiled and used
without the scale filter.

Deprecate av_parse_video_frame_size() and av_parse_video_frame_rate()
in favor of the newly added corresponding functions
av_parse_video_size() and av_parse_video_rate() defined in
libavcore/parseutils.h.

This change also adds a linking-time dependency of libavcodec and of...

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:

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.
