[IDEA] waveform visualisation in web player ?

[steve4star]

I was able to generate the following image from a flac file:-
     
using

Code:

ffmpeg -i 04.\ 22\ Acacia\ Avenue.flac -f lavfi -i color=c=black:s=640x320 -filter_complex   "[0:a]showwavespic=s=640x320:colors=white[fg];[1:v][fg]overlay=format=auto" -y  -frames:v 1 /tmp/out.png 2>/dev/null

with guidance from the ffmpeg WIKI
