[FFmpeg-user] anequalizer example error on doc site and manpage

i noticed a small error in the example provided for the anequalizer filter…

ffmpeg . org/ffmpeg-filters.html#Examples-7
ffmpeg . org/ffmpeg-all.html#Examples-42
$ man ffmpeg-all

the params specify:

Set central frequency for band. If input doesn’t have that frequency the entry is ignored.


Set filter type for band, optional, can be:

	Butterworth, this is default.

	Chebyshev type 1.

	Chebyshev type 2.

yet the example shows:

anequalizer=c0 f=200 w=100 g=-10 t=1|c1 f=200 w=100 g=-10 t=1

which should actually be:

anequalizer=c0 cf=200 w=100 g=-10 f=1|c1 cf=200 w=100 g=-10 f=1
