  • ffmpeg return black and white image

    16 décembre 2011, par njai

    Video capture device is kworld dvd maker 2 (em2861)
    It returns the image in "black and white" with green line at the bottom of screen ; but when I tested it with webcam, it worked properly.

    Here is 30s video. http://www.youtube.com/watch?v=7q2wFGVwGGI

    How can I convert it to color ?

    [root@localhost ~]# ffmpeg -f video4linux2 -i /dev/video0 -vcodec mpeg4 -y output.mp4

  • Error : "No such option : -l" when running yt-dlp

    12 juin 2022, par garson

    I have adapted code from this Stack Overflow answer to try to download a video and use ffmpeg to alter it

    


    yt-dlp    "https://www.youtube.com/watch?v=PtkqwslbLY8" -o  ffmpeg -i in.mp4 -vcodec libx264 -crf 23 -preset fast -profile:v baseline \
-level 3 -refs 6 -vf "scale=640:-1,pad=iw:480:0:(oh-ih)/2,format=yuv420p" \
-acodec copy output.mp4


    


    However, when I run this I'm getting the error :

    


    yt-dlp: error: no such option: -l


    


    Any ideas of how to fix this ?
