SampleFormat with AVSampleFormat.

100l: remove bogus inclusion of libavcodec/audioconvert.c in
avfilter.c.

Add a time_base field to AVFilterLink.

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

Use more expressive names for the avfilter_insert_filter() in and out
parameters.

pads, rather than their index.

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...

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.

Deprecate ff_get_plane_bytewidth() in favor of

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.

avfilter: do not crash on null link src/dst in avfilter_destroy()

Originally committed as revision 24719 to svn://svn.ffmpeg.org/ffmpeg/trunk

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:
enum PixelFormat format -> int format in AVFilterBuffer...

Use avfilter_copy_picref_props() along lavfi.

Add version to AVClass so we can add to and use fields of AVClass without ABI issues.

Originally committed as revision 22987 to svn://svn.ffmpeg.org/ffmpeg/trunk

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...

Avoid usage of avcodec_get_pix_fmt_name() and
avcodec_get_chroma_sub_sample(), directly access
av_pix_fmt_descriptors instead.

Remove some of the dependancies of lavfi on lavc.

Originally committed as revision 21575 to svn://svn.ffmpeg.org/ffmpeg/trunk

Make avfilter_insert_filter() print the instance name of the
auto-inserted scale filter, rather than the filter name, as this
provides more information.

Originally committed as revision 21123 to svn://svn.ffmpeg.org/ffmpeg/trunk

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()".

Implement a new registration system for filters.

Create a new static array containing pointers to the AVFilter
definitions, so that the non-constant next filter in the AVFilter
struct is not anymore required and the AVFilter definitions may be
stored in shareable memory....

Make avfilter_get_video_buffer() use
avfilter_default_get_video_buffer() if the get_video_buffer() callback
is not defined in a filter.

Libavfilter filters author have to explicitely define the
get_video_buffer() callback if they want the buffer to be requested to...

Make dprintf_link() show the name of the link pixel format.

Originally committed as revision 20372 to svn://svn.ffmpeg.org/ffmpeg/trunk

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...

Also copy pixel_aspect when copying the picref in avfilter_start_frame.
This avoids a division by zero in '[in]fifo,scale[out]'

avfilter_draw_slice() when the draw_slice callback is not defined in
the input pad.

The filter framework as is hangs with filters that

permission. This is a fix for that.
