FFMPEG Detect volume of streaming (PHP)

Question

I spent last 4 days trying to acheive that but with no luck,

I am trying to detect volume of streaming link or save audio file, using the FFmpeg I tried every single command line.

ffmpeg -f lavfi -i amovie=sample1.aac,volumedetect -f null -y test.txt

Output

There was a problem! Array (

    [10] => Unknown input format: 'lavf'
)

Basically my problem now is :

 Unknown input format: 'lavf'

Any help please

My FFMpeg Version is

[root@bea ~]# ffmpeg -formats | grep lavfi

I think your ffmpeg is too old to support lavfi. Find out by doing ffmpeg -formats. lavfi should be part of the list? You can try

ffmpeg -formats | grep lavfi

The following works fine otherwise.

ffmpeg -f lavfi -i amovie=sample1.aac,volumedetect
