  I'm trying to convert a .ts file with this output to mkv :

  To do that I'm using this command :

  


  ffmpeg -i input.ts -c copy output.mkv


  


  But the conversion fails with this error :

  What should I do in order to fix this ? I've already tried to add -fflags +genpts in the beginning but it fails anyway.

  


  EDIT : I did solve it by using MKVToolNix instead.

  


• fluent-ffmpeg add multiple languages from method dynamically nodejs

  18 février 2021, par AmitKumar

  I am trying to add multiple languages and subtitles to a video dynamically. but I am not able to find any solution, I found many results for the command line.

  


  I want to call this command script from my nodejs method

  


  ffmpeg -i captain-marvel-trailer.mp4 -i tamil.mp3 -i telugu.mp3 -i hindi.mp3 -map 1 -map 2 -map 3 -metadata:s:a:0 language=eng -metadata:s:a:1 language=tam -metadata:s:a:2 language=tel -metadata:s:a:3 language=hin -codec copy multilanguage.mp4


  


  Here is my codes :

  


  lodash.each(payloadData.languages,function(language){
    let start = 0;
    let max = payloadData.languages.length;
    while (start < max) {
        // fname = `${path.resolve(`contents/hindi.mp3`)} -map 1 -metadata:s:a:0 language=hin -codec copy ${finalVideoPath}`
        // ffmpeg().input(fname)        
        start += 1;
    }
})
    
ffmpeg('./sample.mov')
    .withOutputFormat('.mp4')
    .size('1920x1080')
    .on("end", function (stdout, stderr) {  

    })
}).on("error", function (err) {
    console.log("an error happened: " + err.message);
}).save(finalVideoPath)


  


• avformat/wavenc : Fix leak and segfault on reallocation error

  22 février 2021, par Andreas Rheinhardt

  avformat/wavenc : Fix leak and segfault on reallocation error
  Up until now, the wav muxer used a reallocation of the form ptr =
  
  av_realloc(ptr, size) ; that leaks upon error. Furthermore, if a
  
  failed reallocation happened when writing the trailer, a segfault
  
  would occur due to avio_write(NULL, size) because the muxer only
  
  prints an error message upon allocation error, but does not return
  
  the error.
  Moreover setting the pointer to the buffer to NULL on error seems to
  
  be done on purpose in order to record that an error has occured so that
  
  outputting the peak values is no longer attempted. This behaviour has
  
  been retained by simply disabling whether peak data should be written
  
  if an error occurs.
  Finally, the reallocation is now done once per peak block and not once
  
  per peak block per channel ; it is also done with av_fast_realloc and not
  
  with a linear size increase.
