  avdevice/dshow : discover source color range/space/etc
  Enabled discovering a DirectShow device's color range, space, primaries,
  
  transfer characteristics and chroma location, if the device exposes that
  
  information. Sets them in the stream's codecpars.

• 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
