  • exec.Command error, no output to stdout or stderr

    19 février 2019, par n3wton

    I am trying to get the duration of a video using ffprobe and exec.Command but I keep getting an error. However, stdout and stderr are both empty so I don’t know what the problem is.

    func getVideoLength(filename string) float64 {
    
cmd := exec.Command("ffprobe", "-i", filename, "-show_entries", "format=duration", "-v", "quiet", "-of", "csv=\"p=0\"")
    
fmt.Println("ffprobe", "-i", filename, "-show_entries", "format=duration", "-v", "quiet", "-of", "csv=\"p=0\"")
    
    var out bytes.Buffer
    
    var stderr bytes.Buffer
    
    cmd.Stdout = &out
    
    cmd.Stderr = &stderr
    
    err := cmd.Run()
    
    if err != nil {
    
        fmt.Println("out: " + out.String())
    
        fmt.Println("stderr: " + stderr.String())
    
        log.Fatal(err)
    
    }
    

    
    length, err := strconv.ParseFloat(out.String(), 64)
    
    if err != nil {
    
        log.Fatal(err)
    
    }
    

    
return length
    
}

    Here is the output I get :

    ffprobe -i amelie.mp4 -show_entries format=duration -v quiet -of csv="p=0"
    
out: 
    
stderr: 
    
2019/02/18 21:04:39 exit status 1

    not very helpful.

    Any ideas ?. Thanks.

  • FFMPEG recording get an error when camera is turned off

    29 novembre 2019, par Bogdan Rudnytskyi

    I have a video recording service using ffmpeg.
    When the camera is turned off, I don’t get an error and the service freezes.
    Please help me how I can configure recording so that this service crashes with an error ? (and I will use Supervisor).
    Maybe I need to insert some flag ?
