  • blur an mp4 video for website background

    14 décembre 2015, par Mansi

    I am putting a video in the background of my web page. I want to blur the background for which I tried to put the following attribute in video tag :

     <video>
    
</video>

    the video runs very slow due to blurring the background within HTML.
    So, now I am trying to blur the original video. I tried to use ffmpeg (here) :

    ffmpeg -i input.avi -vf "boxblur=enable='between(t,start,end)'" -codec:a copy output.avi

    But the filter used in ffmpeg seems to be deprecated. I have tried few filters of "avconv", but no filter seems to "blur" the video.
    Please let me know if there is any other command line tool which I can use for this purpose or even if I am missing any filter in ffmpeg or avconv.

    UPDATE : Console output for ffmpeg :

    ffmpeg -i output.mp4 -vf "boxblur=enable='between(t,0,15)'" -codec:a copy output1.mp4
