  • nodejs FFMPEG argument issues

    16 août 2016, par shaun

    When I put the following command in the command line FFMPEG works completely correct and mute’s the sections of the video as expected.

    Best I can think is it has something to do with the \’ in volStr but I don’t know how to create it any other way.


    after @Mulvya comment I changed my for loop to

    var volStr = '';
    for (var i = 0; i < arrPairs.length; i++) {
       volStr += "volume=enable='between(t," + arrPairs[i].start + "," + arrPairs[i].end + ")':volume=0";
       if (i !== arrPairs.length - 1) {
           volStr += ",";
       }
    }

    getting rid of the space between each grouping and it worked beautifully.

  • AFTER PHP-FFMpeg not converting (error with ffmpeg)

    15 août 2016, par Magurean Dan Sergiu

    I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

    Unknown encoder 'libx264'

    My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

    After a few modifications

    I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.
