    Préambule
    Cet article n’a pas pour but de détailler les installations de ces logiciels mais plutôt de donner des informations sur leur configuration spécifique.
    Avant toute chose SPIPMotion tout comme MediaSPIP est fait pour tourner sur des distributions Linux de type Debian ou dérivées (Ubuntu...). Les documentations de ce site se réfèrent donc à ces distributions. Il est également possible de l’utiliser sur d’autres distributions Linux mais aucune garantie de bon fonctionnement n’est possible.

  • Weird bug with FFMPEG when adding path (escape character \ )

    15 juillet 2018, par alan samuel

    I am using C# to execute some FFMPEG commands.

    I have a FFMPEG command like this -

        ffmpeg -i C:\\Users\\Alan\\source\\repos\\TEST\\Tem_Videos/24d4a5be-5615-7930-5a38-c4e191aa8c48.mp4 
    
-i C:\\Users\\Alan\\source\\repos\\TEST\\Video_Templates/Redacted.png -filter_complex "[0:v][1:v]overlay=0:0:enable='between(t,2,3)',drawtext=fontfile='C\\:\\Users\\Alan\\source\\repos\\TEST\\FFMPEG\\FreeSerif.ttf':enable='between(t,2,3)':fontcolor=white:fontsize=50:text='This section has been redacted':x=(w-text_w)/2:y=(h-text_h)/2[v];[0]volume=0:enable='between(t,2,3)'[a]" -map "[v]" -map "[a]" -preset ultrafast C:\\Users\\Alan\\source\\repos\\TEST\\Tem_Videos/6b70aeea-26fb-45ad-b7ad-254803f3e610.mp4"

    I am adding the escape characters when generating paths. But when using drawtext the command - drawtext=fontfile='C\\:\\Users\\Alan\\source\\repos\\TEST\\FFMPEG\\FreeSerif.ttf'

    This always fails when it runs.

    If I run the command in cmd after changing the ’C// :’ to ’C/ :’ it works.

    How do we get around this when I need to add a custom path for the font ?

    Here is how I am setting the command in C#

     string fontpath = System.Web.HttpContext.Current.Server.MapPath("~/FFMPEG/FreeSerif.ttf");
    
            fontpath = fontpath.Replace(":", @"\:");
    
            string ffmpegfile = System.Web.HttpContext.Current.Server.MapPath("~/FFMPEG/ffmpeg.exe");
    
            string commandtorun = " -i " + inputvideo + " -i " + overlay + " -filter_complex \"[0:v][1:v] overlay=0:0:" +
    
                "enable='between(t," + starttime + "," + endtime + ")',drawtext=fontfile='" + fontpath + "':enable='between(t," + starttime + "," + endtime + ")':fontcolor=white:fontsize=50:text='This section has been redacted':x=(w-text_w)/2:y=(h-text_h)/2[v];[0]volume=0:" +
    
                "enable='between(t," + starttime + "," + endtime + ")'[a]\" -map \"[v]\" -map \"[a]\" " +
    
                "-preset ultrafast " + finaloutput;

  • Using a pipe character | with child_process spawn

    19 avril 2020, par Titan

    I'm running nodejs on a raspberry pi and I want to run a child process to spawn a webcam stream.

    



    Outside of node my command is :

    



    raspivid -n -mm matrix -w 320 -h 240 -fps 18 -g 100 -t 0 -b 5000000 -o - | ffmpeg -y -f h264 -i - -c:v copy -map 0:0 -f flv -rtmp_buffer 100 -rtmp_live live "rtmp://example.com/big/test"


    



    With child_process I have to break each argument up

    



    var args = ["-n", "-mm", "matrix", "-w", "320", "-h", "240", "-fps", "18", "-g", "100", "-t", "0", "-b", "5000000", "-o", "-", "|", "ffmpeg", "-y", "-f", "h264", "-i", "-", "-c:v", "copy", "-map", "0:0", "-f", "flv", "-rtmp_buffer", "100", "-rtmp_live", "live", "rtmp://example.com/big/test"];


    



    camera.proc = child.spawn('raspivid', args);


    



    However it chokes on the | character :

    



    error, exit code 64
Invalid command line option (|)


    



    How do I use this pipe character as an argument ?
