Hi Paul,

Working version:

Filter drawtext
  Draw text on top of video frames using libfreetype library.
    Inputs:
       #0: default (video)
    Outputs:
       #0: default (video)

No sign of libharfbuz, but it works obviously.

Then, the latest build / snapshot from evermeet:

Unknown filter 'drawtext'.

So yes, it’s not my command line, it’s either the build or an FFmpeg problem, but I’m not the one who can judge.
It is however a bit annoying, as I’m not supposed to distribute binaries, so I let the end users download from within my work. And thus I rely on stuff not breaking too often. (I do have a couple of thousand users for my products, most of them use FFmpeg somewhere.)
