• How to resolve Electron ffmpeg error opening input file ?

  26 août 2023, par 3V1LXD

  I have an Electron app with ffmpeg.exe inside the project's bin folder. When i try to use ffmpeg to make a new video I get an error reading the input file.

  


  FFmpeg error: [in#0 @ 000002667f2ab9c0] Error opening input: No such file or directory

Error opening input file C:/Users/xxxx/Videos/Powder/2023.08.19%2017.30.37_Apex_Legends/Powder_2023.08.19%2021.00.48.mp4


  


  const ffmpeg = spawn(ffmpegPath, [
  '-i', videoFile,
  '-filter_complex', filterComplex,
  '-map', '[out]',
  '-c:v', 'libx264',
  '-crf', '18',
  '-preset', 'veryfast',
  '-y',
  path.join(outputDir, outputName)
]);

ffmpeg.stdout.on('data', (data) => {
  console.log(`FFmpeg output: ${data}`);
});

ffmpeg.stderr.on('data', (data) => {
  console.error(`FFmpeg error: ${data}`);
});

ffmpeg.on('close', (code) => {
  console.log(`FFmpeg process exited with code ${code}`);
  event.reply('ffmpeg-export-done'); // Notify the renderer process
});


  


  How can i resolve this path issue ?

  


• Is there a way to use pdf images with the saveVideo function of R's animation package ?

  11 avril 2023, par Hullaballoon

  I've created a few MP4 files using the saveVideo function in the animation package, but the colours are relatively dull in one of them. I've compared the output of one of the images in the animation by producing a PNG and a PDF, with the colours in the PDF appearing much bolder. I was hoping to code the images as PDFs within the animation to see if it improves the output, but I am getting stuck with a message "Rplot.pdf : Invalid data found when processing input" and no MP4 being produced.

  


  The internal code of the saveVideo function implies that PDF images can be used with the following :

  


  num = ifelse(file.ext == "pdf", "", ani.options("imgnfmt"))


  


  Here's a toy example that demonstrates the issue. This works fine :

  


  library(animation)
saveVideo({
  darkcol = "#000000"
  par(bg = darkcol)
  ani.options(interval = 0.5)
  for (i in 1:10)
  {
    plot(0:10, runif(11, 4, 8), col = "magenta1")
    ani.pause()
  }
}, video.name = "TestVideo.mp4",
ani.res = 144, ani.height = 900, ani.width = 1600)


  


  This one doesn't work :

  


  library(animation)
saveVideo({
  pdf(ani.options("img.fmt"))
  darkcol = "#000000"
  par(bg = darkcol)
  ani.options(interval = 0.5)
  for (i in 1:10)
  {
    plot(0:10, runif(11, 4, 8), col = "magenta1")
    ani.pause()
  }
}, video.name = "TestVideoPDF.mp4",
ani.res = 144, ani.height = 9, ani.width = 16,
use.dev = FALSE, ani.type = "pdf")


  


  Here is what the console displays when I run the second batch of code :
