After compiling ffmpeg with the --enable-filter=drawtext, when launching the command, it does not recognize the option.

--enable-filter=drawtext does not look like a useful configure option, how did you find it?
Please run ./configure --help to see the relevant options to enable external dependencies, you need --enable-libfreetype.

  • Component changed from undetermined to build system
  • Resolution set to fixed
  • Status changed from new to closed
  • Version changed from unspecified to git-master

The output of configure --help is improved since d9a4db65 and shows now that --enable-libfreetype is needed to enable the drawtext filter.
