• Burning subtitles into video using ffmpeg overlay on react native

  25 avril 2023, par Youssef

  I have managed to complete this task on node server but it's too slow I don't want to upgrade my instance so I decided to do the conversion on the front end, my app is on react native can please somebody help me convert the code and keep the same args and options

  


  Server code

  


  // Execute the ffmpeg command to burn the subtitles into the video
const ffmpeg = spawn("ffmpeg", [
  "-i",
  "pipe:0",
  "-vf",
  `subtitles=${subtitlePath}:force_style='Alignment=10,OutlineColour=&H100000000,BorderStyle=3,Outline=1,Shadow=0,Fontsize=10'`,
  "-c:a",
  "copy",
  "-progress", "pipe:1",
  outputPath,
]);

// Pipe the videoResponse array buffer to FFmpeg
ffmpeg.stdin.write(videoResponse.data);
ffmpeg.stdin.end();

// Send the output file as a response once the process is complete
ffmpeg.on("close", () => {
  fs.readFile(outputPath, (err, data) => {
    if (err) {
      console.error(err);
    } else {
      console.log(outputPath)
    }
  });
});


  


  My try on react native but failed for several issues including, main ones are :

  


  


  No such filter : 'subtitles' Failed to inject frame into filter

  


  


  


  Invalid argument

  


  


  


  Error initializing complex filters.

  


  


  This is what I come up with so far

  


    componentDidMount() {
    FFmpegKit.executeAsync(`-i ${inputFilePath} -i ${subtitleFilePath} -filter_complex "[0:v][1:s]overlay=10:main_h-overlay_h-10" -c:a copy ${outputFilePath}`)
    .then((session) => {
      FFmpegKit.cancel();
  
      const returnCode = session.getReturnCode();
  
      if (ReturnCode.isSuccess(returnCode)) {
        console.log('Video with subtitles was created successfully!');
      } else {
        console.log('Error creating video with subtitles');
      }
    })
    .catch((error) => {
      console.log('Error creating video with subtitles', error);
    });
  }

  Command line:
  
  ffmpeg -y -i /tmp/php2hmlyt  -acodec copy /home/uploads/5607.mp3
