  • Create video with ffmpeg from youtube URL ?

    24 septembre 2014, par agustinalesso

    I’m creating a video player for an e-learning platform with javascript. We let our users to upload videos or images & audio from files or youtube videos via URL. When it’s not a Youtube URL, we convert the files in our servers using FFMPEG so our player only handles the same type of files, but I’m having some issues to control the Youtube video from our own controls. What I want to know : Is there a way to take the youtube URL and create a video file using FMMPEG or some other similar way ? The Idea is NOT to control youtube videos using the youtube API, but using instead our own controls.

  • Mix voiceover and background music with delay and volume

    6 août 2019, par oldman

    I don’t master ffmpeg but I really need to mix a voiceover with a background song.

    The voiceover must start 5 seconds after the song, and must end 5 seconds before the song ends.

    The music volume must be loud for the first 5 seconds and the last 5 seconds, but during the voiceover it should remain low.

    Searching the internet, the closest I could come to my goal was this :

    ffmpeg -i music.mp3 -i voiceover.mp3 -filter_complex "[0]asplit[a][b]; [a]atrim=duration=5,volume='1-max(0.25*(t-13),0)':eval=frame[pre]; [b]atrim=start=5,asetpts=PTS-STARTPTS[song]; [song][1]amix=inputs=2:duration=shortest:dropout_transition=0[post]; [pre][post]concat=n=2:v=0:a=1[mixed]" -map " "[mixed]" output.mp3

    Could someone help me complete this script ?
