• How can we reduce the size of audio file after uploading ?

  8 novembre 2019, par Arjun Pujari

  I have used this command in the terminal to install the package : composer require pbmedia/laravel-ffmpeg. The package is successfully downloaded, but I don’t know how to use it. I don’t even know if this package can also reduce the audio file size or not.

  Anyone know any other library or package ?

      
  
          <form action="{{route('upload')}}" method="post" enctype="multipart/form-data">
  
              Select Audio to upload:
  
              <input type="file" />
  
              <input type="submit" value="upload MP3" />
  
          </form>
  
      
  
  
  
  
  
  &lt;?php

  Here is my controller. Write basic code for save file :

  namespace App\Http\Controllers;
  
  
  
  use Illuminate\Http\Request;
  
  use Pbmedia\LaravelFFMpeg\FFMpeg;
  
  
  
  class FileCompress extends Controller
  
  {   
  
      public function compressFile(Request $request)
  
      {
  
            $uploadFileName = mt_rand().time(). '.' . $file->getClientOriginalExtension();
  
            $filetype = substr($file->getClientMimeType(), 0, strpos($file->getClientMimeType(), "/"));
  
  
  
          if($filetype == 'video'){
  
  
  
            $localpath =  public_path().'/videos/'.$uploadFileName;
  
           //code for video file compress.
  
          }else{
  
            //code for audio file compress.
  
          }
  
      }
  
  }

  But I need to reduce the audio file size when a file is uploaded or reduce the file size immediately after the file upload. How can i do that ?

• ffmpeg select highest quality video track and audio track in specific language from m3u8

  17 juin 2019, par smfs

  I have a bunch of .m3u8 files that contain video tracks in different resolutions and bitrates, and audio tracks in different laguages.
  I want to select the highest quality video stream and if available the audio track in a specified language.

  I know how to select the audio track, currently I use

  -map 0:m:language:en? 

  like this

  ffmpeg -re -protocol_whitelist file,http,https,tcp,tls -i .\some_file.m3u8 -codec:a aac -c:v copy -f flv -map 0:m:language:en? rtmp://foo.com:1935/live/xyz

  With that I only stream audio if the specified audio language is available, or audio and video in the default configuration if it’s not.

  I want to stream the best video track (the one ffmpeg picks by default) in both cases.

• Im getting error when generating thumbnails using ffmpeg in firebase functions

  5 juillet 2020, par Sajjad

  I'm writing this code for generating thumbnail from a video uploaded to firebase storage using FFmpeg, I am saving thumbnails first in the temp directory and then uploading it to firebase storage. The thumbnails are saved in temp dir but I'm getting an error while saving it to firebase storage. (EISDIR ERROR)

  


  const targetTempFilePath = path.join(os.tmpdir(), targetTempFileName);
const targetStorageFilePath = path.join(path.dirname(filePath), targetTempFileName);
ffmpeg.ffprobe(req.body.videoUrl, (err, metaData) => {
    if (err) {
      console.log(err);
    }

    fileDuration = metaData.format.duration;
  });

  ffmpeg(req.body.videoUrl)
    .on("filenames", (filenames) => {
      console.log("Will generate " + filenames.join(", "));
      thumbsFileUrl = "" })
    .on("end", () => {
      console.log(targetTempFilePath);
      admin
        .storage()
        .bucket()
        .upload(targetTempFilePath, {
          destination: targetStorageFilePath,
        })
        .then(() => {
          console.log("Output audio uploaded to", targetStorageFilePath);
          // fs.unlinkSync(tempLocalFile);
          return res.status(200).json({
            success: true,
            thumbsFileUrl: thumbsFileUrl,
            fileDuration: fileDuration,
          });
        })
        .catch((err) => {
          console.log(err);
          return res.json({ success: false });
        });
    })

    .screenshots({
      // Will take screens at 20%, 40%, 60% and 80% of the video
      count: 2,
      folder: targetTempFilePath,
    });
