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.

Use new imgutils.h API names, fix deprecation warnings.

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....

Implement inline function av_fill_image_max_pixstep() and use it for
factorizing code.

Separate video specific BufferRef properties into VideoProps.

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....

7fce481a 08/07/2010 01:15 AM S.N. Hemanth Meenakshisunda...

Rename functions and fields:

avfilter_(un)ref_pic -> avfilter_(un)ref_buffer
avfilter_copy_picref_props -> avfilter_copy_buffer_ref_props
AVFilterBufferRef.pic -> AVFilterBufferRef.buffer

They have been renamed to allow sharing with audio.

ecc8dada 08/07/2010 01:15 AM S.N. Hemanth Meenakshisunda...

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.

Patch by S.N. Hemanth Meenakshisundaram smeenaks@ucsd@edu.

Make config_input() return AVERROR in place of -1.

Compute the max pixel step for each plane, and use it in place of
hardcoding that value in a switch.

More compact and correct.

Remove dependency on avcodec_get_chroma_sub_sample() and libavcodec,
use the pixdesc API instead.

Remove explicit filename from Doxygen @file commands.

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.

Define AVMediaType enum, and use it instead of enum CodecType, which
is deprecated and will be dropped at the next major bump.

Use the new null callbacks to simplify filters and reduce duplicated code.

Use pixel format descriptors for checking if the input format is
paletted. Simpler and more robust.

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()".

Remove from the list of the supported formats the formats which are
not correctly supported.

See the thread:
"[FFmpeg-devel] [PATCH] Remove not truly supported formats support from the crop filter".

Fix crop filter start_frame() for paletted formats different from
PAL8. Shift data1 only if the input format is not paletted.

ac74dfa4 11/08/2009 10:47 PM Stefano Sabatini

Fix start_frame(), which was issuing chroma artifacts with planar
formats with more than 8 bits per pixel (e.g. YUVXXXP16).
