  • Generating an Audio Waveform using ffmpeg in python [closed]

    12 juillet 2021, par Gandharv Bakshi

    I am currently generating a waveform using ffmpeg with the following code :

    


    ffmpeg -y -i INPUT_AUDIO.mp3 -loop 1 -i INPUT_BANNER_IMAGE.png -filter_complex "[0:a]aformat=channel_layouts=mono,showvolume=f=0.5:c=VOLUME:o=v:w=1000:h=200[v] ;[1:v][v]overlay=(W-w)/2 :(H-h)/2[outv]" -map "[outv]" -map 0:a -vcodec libx264 -pix_fmt yuv420p -profile:v main -level 4.0 -acodec aac -shortest -movflags +faststart OUTPUT_NAME.mp4

    


    This works, it gives be a video with the banner + Waveform. However, how do I use ffmpeg-python to do this ?

    


  • Concatenate audio with image and video using ffmpeg

    9 mai 2018, par huynq9

    I have 1 image, 1 audio file and 1 video. I would like to merge all of them to make a video which will

    • show the image and play audio file for the first 10s
    • play the video file

    here is what I was trying to do so far.

    ffmpeg \
    
-loop 1 -framerate 24 -t 10 -i item1.jpg \
    
-i "https://audio-ssl.itunes.apple.com/apple-assets-us-std-000001/Music/66/58/f7/mzi.eoocfriy.aac.p.m4a" \

-filter_complex \

 [2]scale=432:432,setdar=1[vid1]; \ 
    
 [img1][aud1][vid1] concat=n=3:v=1:a=1" \
    
outputfile.mp4

    I got the error :

    initializing complex filters. Invalid argument

    I tried to googled but still cannot figure out what I am doing wrong ?

    Updated :
    I ran the following command :

    ffmpeg \
    
-loop 1 -framerate 24 -t 10 -i item1.jpg \
    
-t 10 -i "https://audio-ssl.itunes.apple.com/apple-assets-us-std-000001/Music/66/58/f7/mzi.eoocfriy.aac.p.m4a" \
