[LINUX] can ffmpeg (or any othe linux command) genere an ANIMATED waveform

[Jintor_Universe]

WHAT I WANT TO DO : generate a video (animated waveform/spectrum) of an audio.

CONTEXT : web platform (linux web server) were users upload files to a multimedia library (all conversions are automated via command lines).

I KNOW : to use ffmpeg to generate a fixed image with the waveform

-filter_complex "showwavespic=s=963x369:scale=sqrt:colors=#00d7fe"

QUESTION : is there a way via command line to make it like a animated audio reacting spectrum ?

I SAW : this post https://forum.videohelp.com/threads/393114-Generating-animated-frequency-spectrum-bars...audio-to-video => but the proposed solutions are windows with a user interface. I want a command-line without user interface solution. it could be ffmpeg or other...

this generates a fixed frame (not animated)

I found https://github.com/adefossez/seewav

It's a python script that combines caoiro (to generate lines) and ffmpeg to output a .mp4

[poisondeathray]

-vf showwaves
https://ffmpeg.org/ffmpeg-filters.html#showwaves

eg.

ffmpeg -i input.ext  -filter_complex "[0:a]showwaves=s=1920x1080:mode=line:rate=24,format=yuv420p[v]" -map "[v]" -map 0:a -c:v libx264 -crf 18 -c:a copy -t 00:01:00 showwaves.mp4

[/code]

ffmpeg -i input.ext  -filter_complex "[0:a]showwaves=s=1920x1080:mode=line:rate=24,format=yuv420p[v]" -map "[v]" -map 0:a -c:v libx264 -crf 18 -c:a copy -t 00:01:00 showwaves.mp4

[/code]

cool

I managed to create a .mp4 of both

showwaves => https://www.stubfeed.com/media/ownchunx/15223756184271/15223757187185/showwaves.mp4
python seewav => https://www.stubfeed.com/media/ownchunx/15223756184271/15223757187185/15223757187185_stubwav.mp4

I prefer seewav : more smooth, but that is only an opinion.

cheers
