  • Why can’t I run the ffmpeg executable stored in /mnt/sdcard ?

    18 novembre 2024, par user2193172

    I managed to compile the ffmpeg Static build. But when I am trying to call the ffmpeg command line I get a Java IOException : No such file or Directory.

    



    My code is as follows :

    



    public void merge_video(View view){

    if(ffmpeg_file.exists()){
          Log.d(null, "ffmpeg exists");
      }else{
          Log.d(null, "Could not locate ffmpeg in the folder");
      }

      File file1 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4");
      if(file1.exists()){
          Log.d(null,"File 1 exists");
      }
      File file2 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4");
      if(file2.exists()){
          Log.d(null,"File 2 exists");
      }

      String[] ffmpegCommand = new String[5];
      ffmpegCommand[0] = "/mnt/sdcard/com.ffmpeg_test/ffmpeg";
      ffmpegCommand[1] = "-i";
      ffmpegCommand[2] = "concat:/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4|/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4";
      ffmpegCommand[3] = "copy";
      ffmpegCommand[4] = "/mnt/sdcard/com.ffmpeg_test/output.mp4";  

      try {
          Process ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();

          String line;
          BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));
          Log.d(null, "*******Starting FFMPEG");

          while((line = reader.readLine())!=null){

              Log.d(null, "***"+line+"***"); 
          }
          Log.d(null,"****ending FFMPEG****");

    } catch (IOException e) {
        e.printStackTrace();
    }
  }


    



    The LogCat print is as follows :

  • Problems with ffmpeg command line on android

  • How can upload audio on dropbox after converted it from the video format using ffmpeg in nodejs and angular

    21 septembre 2021, par Amir Shahzad

    nodejs server side code

    


    This is my nodejs server side where i want to convert the video into the audio format and then want to upload the converted audio on the dropbox is there any way to do that ??

    


    const express = require('express'),
path = require('path'),
cors = require('cors'),
ffmpeg = require('fluent-ffmpeg'),
fs = require("fs"),
access_token = "My-Access-Token";

ffmpeg.setFfmpegPath('/usr/bin/ffmpeg');

const app = express();
app.use(cors());
app.use(express.json());
app.use(express.urlencoded({
  extended: false
}));


app.post('/api/upload', upload.single('mp4'), function (req, res) {
  if (!req.file) {
    console.log("No file is available!");
    return res.send({
     success: false
  });

  } else {
   function convert(input, output, callback) {
      ffmpeg(input)
          .output(output)
          .on('end', function() {                    
           console.log('conversion ended');
            callback(null);
          }).on('error', function(err){
           console.log('error: ', err);
            callback(err);
          }).run();
    }
     const filepath = req.file.path;
     var content = fs.readFileSync(filepath);

 options = {
    method: "POST",
    url: 'https://content.dropboxapi.com/2/files/upload',
    headers: {
     "Content-Type": "text/plain; charset=dropbox-cors-hack" ,
     "Authorization": "Bearer " + access_token,
      "Dropbox-API-Arg": "{\"path\": \"/youtube- 
       radio/"+req.file.originalname+"\",\"mode\": \"overwrite\",\"autorename\": 
       true,\"mute\": false}",
    },
     body:content
};
convert(filepath,  options+'.mp3', function(err,res, body){
   if(!err) {
    console.log('File Name is',req.file.originalname);
    console.log('File Path Is = ',req.file.path)
    console.log('conversion complete');   
    console.log('ERR', err);
   }
});
console.log('File is available!');
return res.send({
  success: true
})
}
 });


  const PORT = process.env.PORT || 8080;
  const server = app.listen(PORT, () => {
  console.log('Connected to port ' + PORT)
  })


    


    i have read many documentations of dropbox and ffmpeg and angular file upload but i could not understand Please anyone can resolve my code Thanks in advance

    


    This is my typescript file

    


    import { Component, OnInit } from '@angular/core';
import { FileUploader } from 'ng2-file-upload';
import { ToastrService } from 'ngx-toastr';
import { Track } from 'ngx-audio-player'; 
import { PlayerServiceService } from './services/player-service.service';


const URL = 'http://localhost:8080/api/upload';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit{

public uploader: FileUploader = new FileUploader({
  url: URL,
  itemAlias: 'mp4'
});
 constructor(private toastr: ToastrService,
    private playerService: PlayerServiceService) { }

 ngOnInit(): void {
   this.uploader.onAfterAddingFile = (file) => {
     file.withCredentials = false;
 };
  this.uploader.onCompleteItem = (item: any, status: any) => {
    console.log('Uploaded File Details:', item);
     this.toastr.success('File successfully uploaded!');
  };

}
}


    


    This is html code

    


     <div class="container mt-5">&#xA;  <div class="file-upload">&#xA;     <input type="file" ng2fileselect="ng2fileselect" />&#xA;     <button type="button" class="btn btn-info">&#xA;      Upload&#xA;    </button>&#xA;  </div>&#xA;</div>&#xA;
