[FFmpeg-user] Waveform to video

[Olivier Daubry]

Hello everyone,

Kind of new here but thought that I could possibly find people that could
help me over there. Anyway thanks for reading this.
I would be looking for a software that could convert an audio file to a
video clip of the waveform moving (such as in any playing DAW) with a fixed
playhead.
Zoom would be like 5 seconds of audio but this is secondary.

Does this already exist ? Would ffmpeg help me achieve this ?

Thanks everyone, hoping this won't need crazy development ^^

Cheers,
Olivier

I'm guessing you missed the reply to your first message:
<https://lists.ffmpeg.org/pipermail/ffmpeg-user/2017-October/037400.html>
...but it wasn't very helpful because it points you to the gigantic,
monolithic help file variant and to the video waveform monitor filter
which is not what you want.

See showwaves and showwavespic filters:
http://ffmpeg.org/ffmpeg-filters.html#showwaves
http://ffmpeg.org/ffmpeg-filters.html#showwavespic

If it must "slide" you can use showwavespic filter as the foreground,
color filter as the background, and overlay filter to slide it.

Non-subscribed users do not get direct replies so I CC'd you. See the
archives (via my first link) to see if there are replies by others.

Oh thanks for you message ! Indeed, I've missed the first answer. I'll dig
that.
Thanks for your help, it also confirm that there currently aren't any
software or tool allowing to do that.

Cheers
