help with anlmdn filter

[jjgp]

Hi!
Please Can someone help me to use the anlmdn filter?

I'm trying to use this command on Windows 10 with ffmpeg version N-92730-g978c935f2f

Code: Select all

ffmpeg -y -i $Inputfile -af anlmdn=s=1:p=5:r=10 $Output

ffmpeg shows me: AVFilterGraph @ 0000027f6432b500] No such filter: 'anlmdn'

Seem your ffmpeg build is old - check filters supported by your ffmpeg

Code: Select all

ffmpeg.exe -hide_banner -filters >> ff_help_full.txt 

if there is no anlmdn on list then you need to download newer/different ffmpeg.

Thanks for your help pandy!

I've just downloaded the latest Windows FFmpeg Builds:

• Version 4.1.1 -> doesn't have the anlmdn filter

• Version 20190310-5ab44ff (Nightly build) -> Have the anlmdn filter

Is the anlmdn filter a new implementation since the last stable version?

Thanks
