df4c7ae9db asink_abuffer: extend ABufferSinkContext to make it accept lists of formats in input 
This is required for the pending lavfi indev extension, also
consistent with the video buffer sink.

b854c2a709 vf_unsharp: set default chroma size value to 5x5 
The previous default value 0x0 was not good, since it is not even
valid.

63b61d55f9 vf_unsharp: fix out-of-buffer read 
In apply_unsharp(), when y is >= height, prevent out-of-buffer reading
from src, read from the last buffer line in src2 instead.

The check was implemented in the original unsharp libmpcodecs code and
lost in the port.

This also fixes output discrepancy between the two filters.

3560089e12 vsink_buffer: make the buffer cache all the incoming frames 
Allow to cache more than one frame (e.g. for filters which return
more than one frame when avfilter_request_frame() is called on them),
and do not discard previously cached frames when a new one is added.

5f68a91be2 lavfi: remove default config_props() callback and refactor avfilter_config_links() 
Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.

Also remove channel_layout check as it is now negotiated.

61d55fda2b lavfi: tweak display aspect ratio variables in pad and scale filters 
Previously, "dar" and "a" were documented like "input display aspect
ratio", but their actual value was "in_w/in_h".

In order to avoid to break scripts which rely on the "a" variable, the
patch keeps the same semantics but fixes the corresponding docs, and
fixes the semantics of the recently added "dar" variable, which
now correctly expresses the input Display Aspect Ratio value as
"(inw_w/in_h)*sar".

d9c23a0d5a vf_transpose: avoid multiple calls to avfilter_draw_slice() 
avfilter_draw_slice() is already called in the end_frame() callback,

callback.

In particular fix crash occurring with -vf transpose=3,hflip, fix trac
issue #371.
