• Unable to parse option value xxx.srt as image size Error applying option 'original_size' to filter 'subtitles' : Invalid argument

  6 décembre 2023, par gabri yañez vallverdu

  const strFile = `http://localhost:8080/public/srtFiles/nombreArchivo.srt`
    
const localSubtitleFilePath = path.join(__dirname, 'nombreArchivo.srt');

 axios.get(strFile, { responseType: 'arraybuffer' })
    .then(response => {
        fs.writeFileSync(localSubtitleFilePath, Buffer.from(response.data));

        const outputFilePath = path.join(__dirname, '../../../public/videosSubtitled', `${videoName}`);
        console.log('Subtitle File Path:', localSubtitleFilePath);
        console.log('Output File Path:', outputFilePath);

        exec(`ffmpeg -i ${tempFilePath} -vf subtitles=${localSubtitleFilePath} ${outputFilePath}`, function(error, stdout, stderr) {
            if (error) {

  Hi, I'm trying to add subtitles to a video with ffmpeg in a NodeJS app, but I have this error :
[Parsed_subtitles_0 @ 0000024140111580] Unable to parse option value xxx.srt as image size Error applying option 'original_size' to filter 'subtitles' : Invalid argument

  


  I have tried to send the srt file by a public url and by a local file, but I have also a mistake.

  


• mp3 audio merging with -itsoffset using ffmpeg : no effect

  30 mai 2019, par Itzhak

  I use ffmpeg to merge mp3’s in my node server. It works but the offset doesn’t have any effect..
  I can’t see what is wrong then i’d like to get your help :)

  var command = "ffmpeg -i "+ input1+ " -itsoffset 40 -i " + input2 +" -filter_complex amerge -c:a libmp3lame -q:a 4 "+ output;
  
  
  
          exec(command, function (error, stdout, stderr) {
  
              if (stdout) console.log(stdout);
  
              if (stderr) console.log(stderr);
  
  
  
              if (error) {
  
                  console.log('exec error: ' + error);
  
                  response.statusCode = 404;
  
                  response.end();
  
  
  
              } else {
  
                  // Do something
  
              }
  
  
  
          });

  I tried it also on my computer just in the terminal and it also works with the same problem..

  Thanks,
  Itzhak

• Ffmpeg returning error code 1 in AWS Lamda function

  14 avril 2018, par Tometoyou

  I’m running a lambda function which takes an mp4 video, and adds a watermark of a png image over the top of it in the bottom right hand corner (with a 10px margin). It then outputs that image to a temporary location. It keeps failing with Error code 1, but that isn’t very helpful. I’m using a binary version of ffmpeg that is specified in the main directory of the code. I know that ffmpeg is set up correctly due to using it in another lambda function in this way, which works. But adding an overlay fails. Here is the relevant part of my code :

  function addWatermark(next) {
  
      var ffmpeg = child_process.spawn("ffmpeg", [
  
        "-i", target, // url to stream from
  
        "-i", watermarkPath,
  
        "-filter_complex" ,"overlay=x=W-w-10:y=H-h-10:format=rgb,format=yuv420p",
  
        "-c:a", "copy",
  
        "pipe:1"
  
      ]);
  
      ffmpeg.on("error", function(err) {
  
        console.log(err);
  
      })
  
      ffmpeg.on("close", function(code) {
  
        if (code != 0 ) {
  
          console.log("child process exited with code " + code); // Always exits here.
  
        } else {
  
          console.log("Processing finished !");
  
        }
  
        tmpFile.end(); 
  
        next(code);
  
      });
  
      tmpFile.on("error", function(err) {
  
        console.log("stream err: ", err);
  
      });
  
      ffmpeg.on("end", function() {
  
        tmpFile.end();  
  
      })
  
      ffmpeg.stdout.pipe(tmpFile)
  
      .on("error", function(err){
  
        console.log("error while writing: ",err);
  
      });
  
  }

  Can anyone spot what may be wrong ?

  UPDATE

  I’ve managed to print out some more logs, I’m getting the error :

  [NULL @ 0x42923e0] Unable to find a suitable output format for 'pipe:1'
