Hi,
I was thinking about introducing support for meta() function in the
expression evaluation language. As the ffmpeg filters gradually add
support for metadata, it would be convenient to do something like this:
> ffmpeg -i input.webm -vf
> cropdetect,crop=x=meta('lavfi.cropdetect.x'):y=meta('la
the libavfilter/vf_blackframe.c filter now not only logs detected
values, but also sets frame metadata. Currently, only `pblack` value is set
but `SET_META` macro has been introduced to ease development in the future.
