FFMPEG : Set Opacity of audio waveform color
13 août 2018, par Software Development ConsultanI was trying to do transparency in waveform generated. It seems there is not direct option in ’showwaves’ filter so I came across ’colorkey’ which might help.
I am trying with following :
ffmpeg -y -loop 1 -threads 0 -i background.png -i input.mp3 -filter_complex "[1:a]aformat=channel_layouts=mono,showwaves=s=1280x100:rate=7:mode=cline:scale=sqrt:colors=0x0000ff,colorkey=color=0x0000ff:similarity=0.01:blend=0.1[v] ; [0:v][v] overlay=0:155 [v1]" -map "[v1]" -map 1:a -c:v libx264 -crf 35 -ss 0 -t 5 -c:a copy -shortest -pix_fmt yuv420p -threads 0 test_org.mp4
So I wanted to blue color waveform and wanted to set opacity of that 1 to 0 let say. But it seems this generates blackbox which is actual background of ’1280x100’. I want to keep background of waveform transparent and just wanted to change opacity of waveform only.
Result of my command : enter image description here
Can you please let me know your suggestion
@Gyan, this is with reference to following question which you have answered.
Thanks, Hardik
