I am testing cropping video using the bitstream filter shown in the following
command:
C:\ffmpeg-2020-11-18-git-e3081d6f4f-full_build\bin>ffplay.exe "Input.mp4"
-codec:v copy -an -bsf:v h264_metadata=crop_top=128 "output_cropped.mp4"

Failed to set value 'h264_metadata=crop_top=128' for option 'bsf:v': Option not

Very grateful to anyone who can point out where I am going wrong here, it
looks simple enough.
