This also allows to remove a linking dependency of libavfilter on
libavcodec.

This is required for allowing a filter to use a time base different
from AV_TIME_BASE_Q, as it was previously assumed.

This is required to make AVFilterBufferRef able to contain also audio
data, required by audio filtering integration.

Define a new struct AVFilterBufferRefVideoProps and add a type field
to AVFilterBufferRef.
Video specific properties in AVFilterBufferRefVideoProps are now
referred to by *video pointer in AVFilterBufferRef.

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
AVFilterBufferRef.

They have been renamed to allow sharing with audio.

The struct is going to be used for storing audio buffer references as
well, and the new name is more generic.

ff_fill_pointer().
Also remove a dependency on libavcodec.
Originally committed as revision 24586 to svn://svn.ffmpeg.org/ffmpeg/trunk
This is needed to make the libavfilter framework work with audio
filters.
In particular add a type field to AVFilterLink, change the field types:
enum PixelFormat format -> int format in AVFilterBuffer
enum PixelFormat *formats -> int *formats in AVFilterFormats
enum PixelFormat *format -> int format in AVFilterLink
and change the function signatures:
AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
AVFilterFormats *avfilter_make_format_list(const int *fmts);
int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
int avfilter_add_format(AVFilterFormats **avff, int fmt);
AVFilterFormats *avfilter_all_colorspaces(void); ->
AVFilterFormats *avfilter_all_formats(enum AVMediaType type);
This change breaks libavfilter API/ABI.

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.

The struct is going to be used for audio data as well, so the new name
is less misleading.

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.

size of the output link of the destination filter, rather than of the

In particular this fixes a crash in the rotate filter.
Originally committed as revision 21238 to svn://svn.ffmpeg.org/ffmpeg/trunk
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()".
Originally committed as revision 20734 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()".

avfilter_draw_slice() when the draw_slice callback is not defined in

Originally committed as revision 16554 to svn://svn.ffmpeg.org/ffmpeg/trunk
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".
