Metadata flags do exist for rotating, but not for flipping. Thus this

I'm irritated. Here I can read, that it exists:
https://ffmpeg.org/ffmpeg-all.html#h264_005fmetadata
So is this an error in the documentation, or what can I learn from this?
That's a H.264 bitstream filter. It can only be used on H.264 video streams.
Basic syntax is
ffmpeg -i input -c copy -bsf:v
h264_metadata=display_orientation=insert:flip=horizontal output
