• Using ffmpeg and ffmpeg-cli-wrapper (Java) to remove black frames in a mp4 video made by Twilio [closed]

  3 janvier 2024, par Duc Nguyen

  I am using Programmable Twilio, when 2 users are recording and pause, there is a silence space with black frames in the output.
Is there a way in Twilio or in ffmpeg to remove all black frames (empty-silent spaces) ? I am using Java and ffmpeg-cli-wrapper

  


  I tried this https://video.stackexchange.com/questions/16564/how-to-trim-out-black-frames-with-ffmpeg-on-windows but it did not help.

  avformat/dtsdec : make S16LE discrimination sharper
  Both S16LE as well as DTS can have lots of 0 bytes in silent segments
  
  Using these results in error. Thus this patch skips 0 bytes in
  
  comparission.

• error when trying to merge audio and video with fluent-ffmpeg

  24 août 2022, par Carlos Zalazar

  Hello I need to combine a video track and an audio track, I get the video and audio from a url.

  


  the problem is that the audio is only added to the middle of the video, and then the video goes silent I hope you understand me, my English is not very good.

  


  dependencies

  


  import ffmpegInstaller from '@ffmpeg-installer/ffmpeg';
import ffmpeg from 'fluent-ffmpeg';

ffmpeg.setFfmpegPath(ffmpegInstaller.path);


  


  code

  


  ffmpeg()
.addInput(video)
.addInput(audio)
.output('videoNuevo.mp4')
.outputOptions(['-map 0:v', '-map 1:a', '-c:v copy'])
.on('progress', progress => {
    console.log(progress)
}).on('end', () => {
    console.log('process finish!')
}).on('error', err => {
    console.log(err)
})
.run()
