  14 juin 2017, par dev

  I am working on to play the mp4 videos from google drive but I am facing the problem that some mp4 files are playing well while some mp4 files are not playing at all insteal "file not found" error shows.

  This is what I am doing.

  https://drive.google.com/file/d/0BwnSGB-C8mEGUmY2U1dhcVNiWjQ/view?usp=sharing

  My code is :

  jwplayer("player_embed").setup ({
  
        file:   "https://docs.google.com/uc?id=0BwnSGB-C8mEGUmY2U1dhcVNiWjQ",
  
        type:   "mp4",
  
        primary: "flash",
  
        image: image_link,
  
        width:  950,
  
        height: 370,
  
        tracks:[{
  
          file: subtitle_link,
  
          label: "English",
  
          kind : "captions",
  
          default: "true",
  
        }] 
  
        });

  is there any mime type issue or something else I need to do ?
  is there any other player that can play videos,subtitles,image poster from google drive ?

• FFMPEG : Error writing trailer of v%v/index.m3u8 : Cannot allocate memory

  7 avril 2023, par user3309447

  I wanted to convert one video track and 2 audio tracks to HLS by combining them.
That means, the HLS conversion has to be multi-bitrate and multi-language both.

  


  What do I want to achieve ?
I have to prepare an HLS stream for 3 resolutions, namely, 720px, 480px and 360px.
Also, there will be 2 audio tracks in the resultant stream, one English and another Hindi.
I am running the below command and getting the error as described below.
Can anybody help me out ?

• 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()
