• Evolution #3603: Ergonomie des onglets de sélection des plugins

  21 April 2020, by chan kalan

  Je suis assez d’accord avec Rastapopoulos, avoir un onglet pour les mises à jour donnerait l’impression d’une liste supplémentaire, en plus des actifs, des inactifs et des verrouillés, et ce serait trompeur. Donc le filtre semble bien dans la liste en cours.
  Dans le système actuel, on peut quand même mettre à jour un plugin qui n’est pas activé : je ne sais pas s’il faut garder...

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

  19 February 2019, by 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.
