d5c66d9c56 vf_setdar: make config_props work properly when called multiple times. 
Do not overwrite the variable set through AVOptions.

b3ea76624a vf_aspect: use the name 's' for the pointer to the private context 
This is shorter and consistent across filters.

7e350379f8 lavfi: switch to AVFrame. 
Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

565e4993c6 lavfi: merge start_frame/draw_slice/end_frame 
Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

568c70e79e lavfi: convert input/ouput list compound literals to named objects 
A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

51a8049be8 vf_aspect: clear AVFilterLink.cur_buf in start_frame(). 
The buffer is passed on to the next filter, so we shouldn't keep any
pointers to it.

a5e8c41c28 lavfi: remove 'opaque' parameter from AVFilter.init() 
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

c04c533f62 lavfi: remove avfilter_null_* from public API on next bump. 
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

cc80caff52 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.

ecc8dada37 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.
