3c4aa50620 lavfi: add field filter 
The filter is a port of libmpcodecs/vf_field.c, since there is no common
code I relicensed it as LGPL, while keeping the original author
copyright.

it simplifies the build system.

This is simpler and also should allow the code to function when the

19add3224f lavfi/scale: implement clever/insane parsing heuristic, and add a size option 
If the first argument can be read as a video size, set that output size
in the scale. This allows to specify in a filtergraph scale=qcif or
scale=320x240.

This is not completely safe, for example in case of a typo in the video
size string the first argument will be read as the input width
expression, giving rise to a confusing comment.
