• RNFFMpeg.executeAsync : Unable to create gif of a video with space(s) in it's source path

  7 juillet 2021, par STBox

  Unable to make gif of a video which has space(s) in it's source directory. All the other video which don't have space(s), their gif is making fine. I had a video whose folder name had space and it was not making gif for it. I copied the same video to a folder without space in it's name, and it made gif for it successfully. Even if I replace the the space with source path with anything like %20 etc, then it says

  


  


  No such file or directory

  


  


  Code snippet

  


  


  


  RNFFmpeg.executeAsync(
          `-i ${source} -ss ${start} -t ${gifDuration}  -vf "fps=5,scale=160:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 ${destination}`, (completedExecution) => {
            if (completedExecution.returnCode === 0) {
              resolve({ path: destination });
            } else {
              resolve({ error: "invalid Gif" });  // always this part executes for videos with space in their source path
            }
          }
        );

  


  


  



  Expected behavior

  


  Regardless a video has or has not a space in it's path, it should make gif correctly and

  


  


  completedExecution.returnCode

  


  


  should be 0

  


  Current behavior
Currently, for all the videos having space in their source path, completedExecution.returnCode is always 1

  


  Logs of the same video without space in folder name

• Anomalie #4830 : extraire_date extravagant

  6 juillet 2021

  Pourquoi pas. Je te propose (ou quelqu’un) de faire une PR pour ça.
  Il faudrait ajouter en même temps des tests unitaires parce que bon.
  Ci dessous un code valide qui fait la demande.

  Ce qui me gène tout de même c’est le [^0-9]* dans la regex (déjà présente dans l’ancienne fonction) qui du coup peut chercher une date coupée dans un grand texte…
  Tel que : "En 2012 à l’orée du bois se trouvait 10 chevaux et 4 biches.", qui sort la date "2012-10-04" (ou 2012-10-01 avant cette proposition).
  Donc l’usage est possiblement assez limité de cette fonction si laissée telle quelle.
