Add "--enable-libharfbuzz" to default build to re-enable drawtext

[Black-Platypus]

drawtext is currently not working anymore under the current build args without libharfbuzz https://trac.ffmpeg.org/ticket/10570#comment:2

I noticed that too today, do you know when was the last working version with drawtext?

The library should probably be autodetected by FFmpeg, it's not nonfree or anything.

Confirmed - build N-112119-gda1d56776c works as expected. Thanks for the quick fix.

drawtext is currently not working anymore in version 6 again.

I see no reason why that would be the case. 6.0 configure does not even know about libharfbuzz: https://git.videolan.org/?p=ffmpeg.git;a=blob;f=configure;hb=refs/heads/release/6.0 6.0 should still work fine without it being explicitly enabled. In fact, trying to enable it would break the build.

Maybe it is not the good place to post this issue. I use the latest static build in a docker container (wget, extract and cp your latest ffmpeg build). I can use anymore the drawtext filter after a rebuild of my container. I can encode mp4 without drawtext filter.

Drawtext filter works again when I revert to a previous version, ffmpeg-5.1.1-amd64-static.tar.xz for instance.

PS : not a docker relative issue.

All versions got the drawtext filter enabled just fine. It was only an issue for a few days with the master builds, cause of the new libharfbuzz dependency. Nothing changed on all release branches. None of that got backported there. So your issue must be something else. You will need to be more specific than "does not work".

Both of those builds are not from here.

[sebmasterid]

Sorry. :-( I will try your build. Many thanks for all your help.
