  • FFMPEG zoompan for continuous zoom in/zoom out from start duration

    10 juillet 2020, par Nikhil Solanki

    I am creating continues zoomin/zoomout effect for input image using this command :

    


    ffmpeg -i combine.mp4 -i image1.jpg -filter_complex "[0]split=2[color][alpha]; 
[color]crop=iw/2:ih:0:0[color]; [alpha]crop=iw/2:ih:iw/2:ih[alpha]; [colo][alpha]alphamerge[v1];
[1]scale=540*2:960*2, setsar=1, zoompan=z='if(lte(zoom,1.0),1.02,max(1.001,zoom-0.0015))':d=25*0.25:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=540x960[v2]; 
[v2]zoompan=z='if(gte(zoom,1.1),1.0,min(zoom+0.0015,1.1))':d=25*0.25:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=540x960[v2];
[v2]curves=vintage, format=yuv444p[v2];
[v2][v1] overlay=1" output_video.mp4 -y


    


    This command will continues zoomin and zoomout input image1.jpg for 1 second and stop after 1 second its OK. But problem is I want perform zoomin zoomout effect after 5 second of video. Video duration is 20s. So, how can I perform zoompan after some duration.

    


  • Find out what device to use for capturing with ffmpeg ?

    14 septembre 2013, par wvxvw

    I'm trying to broadcast my screen and I cannot capture audio. There's one complication however. I don't have pulseaudio, and it simply doesn't work on my system, so installing it is out of question. Below is the command I'm trying :

    ffmpeg -f alsa -i ??? -f x11grab -s 1920x1200 -r 15 -i :0.0 \
    
    -acodec pcm_s16le -vcodec libx264 \
    
    -preset fast -pix_fmt yuv420p -s 1280x800 -threads 0 -f flv "$URL"

    Here's the list of my audio devices :

    I know that ??? should be something like hw:X,Y, but maybe it can be something else. I can't find the corresponding entry in the man page.

    As an aside, it would be great if you can suggest another audio codec. I can't find what are the options, and this particular one isn't compatible with FLV because of too high bitrate.

    PS. This is the error I'm getting :

    Could not write header for output file #0 (incorrect codec parameters ?): Invalid data found when processing input
