  • Where can I find a C/C++ FFmpeg extensive tutorial ?

    22 février 2021, par ticofab

    I want to use ffmpeg (in its c library form) to split a video in more parts, recompose them and encode the final result. Something basic. But it's very difficult to find documentation or hints about this. Where should I look/ask for advice ?

  • FFMPEG zoompan filter cut short my video and slowed it down [on hold]

    9 décembre 2018, par Ewan Sou

    I am using FFMPEG (version 4.0.2) to zoompan my video. My code is as below

    ffmpeg -y -i input.mp4 -loop 1 -i overlay.png -ss 0 -t 10 -filter_complex "[0:v]scale=iw+iw:ih+ih, zoompan=z='if(lte(pzoom,1.0),1.6,max(1.001,pzoom-0.004))':d=1:x='iw/2-(iw/zoom/2)':y='0':s=720x720, setsar=1 [v0];[1:v]crop=720:720,fade=t=in:st=0:d=1,fade=t=out:st=3:d=1[v1];[v0][v1] overlay [v]" -map "[v]" -f mp4 -preset ultrafast -y output.mp4

    Essentially, what this code should do is slowly pan out from the center of my video, with a logo (overlay.png) fading in and out.

    This input.mp4 is 10 seconds. With the above code, the final video duration is 10 seconds still. But its not the full footage, it is cut short and compensated with slow motion to make it 10 seconds still...

    I need the final video to not be cut off at all. It should be the full footage and no slow motion effect.

    Anyone has any ideas what I am doing wrong ?

    Overlay is at : here

    Thanks in advance !
