  • Golang command working in terminal but not with exec package

    17 août 2016, par Jon Stevens

    I am converting a video generation library from NodeJS to GO that primarily uses FFMPEG for all the video processing. I already have all the FFMPEG commands written out to do the generation I want. The issue is that when I try to run the command through the os/exec package, it fails. However, if I copy the exact command and run it directly in the terminal it works and I cannot figure out why that is. My code that runs the command is below :

    command := "ffmpeg -y -loop 1 -i image.png -vf 'fade=in:0:15,fade=out:105:15' -c:v mpeg2video -t 5 -s 1280x720 -r 30 -q:v 1 -preset ultrafast image.mpg"
    

    
parts := strings.Fields(command)
    
cmd := exec.Command(parts[0], parts[1:]...)
    
cmd.Stderr = os.Stderr
    
cmd.Stdout = os.Stdout
    
err := cmd.Run()
    
if err != nil {
    
    panic(err)
    
}

    The ffmpeg error I get when I try to run this code is :

    [AVFilterGraph @ 0x22a9bc0] No such filter : ’fade=in:0:15,fade=out:105:15’

    Error opening filters !

    2016/08/17 17:48:53 exit status 1

    Like I previously stated, if I copy the EXACT command :

    ffmpeg -y -loop 1 -i image.png -vf 'fade=in:0:15,fade=out:105:15' -c:v mpeg2video -t 5 -s 1280x720 -r 30 -q:v 1 -preset ultrafast image.mpg

    and run it directly in the terminal, it works no problem.

    PLEASE HELP.

  • C run linux shell command(fmpeg) slower than typing directly in terminal

    11 novembre 2014, par dadylonglegs

    I’m writing an application that execute a linux shell command (ffmpeg) from my C code. Such as :

    char command[2000];
    
sprintf(command, "ffmpeg -i %s/%s -r 1 -vf scale=-1:120 -vframes 1 -ss  00:00:00 %s.gif", publicFolder, mediaFile, mediaFile);
    
system(command);

    To extract video thumbnail from a specific video. But the strange that it is too much slower when executing shell command form C compare to typing directly to the terminal. I have no idea about this.
    Can anybody help me pls ?. Thanks in advance.
