• How do I combine mkv and mka file using fluent-ffmpeg ?

  17 mai 2020, par YaSh Chaudhary

  I have two Amazon S3 bucket file urls , one is for mkv file(video) and other one for mka(audio).

  



  I am trying to merge audio and video in one file and upload it to S3 but following function doesn't seems to get working. Not getting error also.

  



  client.request({ method: 'GET', uri: uri }).then((response) => {
      const mediaLocation = response.body.redirect_to
      media.push(mediaLocation)
      if(media.length > 1) {
     ffmpeg(media[0])
      .addInput(media[1])
      .output(`${recordingSid}.mkv`)
      .on('error', function (err) {
        console.log('An error occurred: ' + err.message)
      })
      .on('end', function () {
        console.log('Processing finished !')
        var params = {
          Body: fs.createReadStream(`${recordingSid}.mkv`),
          Bucket: config.aws.bucketname,
          Key: `${recordingSid}.mkv`,
        }
        s3.upload(params, function (err, data) {
          //handle error
          if (err) {
            console.log('Error', err)
          }

          //success
          if (data) {
            console.log('Uploaded in:', data.Location)
          }
        })
      })
      }
    })


  



  My ultimate goal is to upload this output to S3 bucket.

  


• FFMPEG "Segmentation fault" with network stream source

  23 décembre 2023, par user11186466

  I use release : 4.2.2 (static) from "https://johnvansickle.com/ffmpeg/"

  



  Final code will be on "Amazon AWS lambda"

  



  Goal : use a url stream and add watermak

  



  Link to video : ​https://feoval.fr/519.mp4

  



  Link to Watermak : ​https://feoval.fr/watermark.png

  



  ./ffmpeg -i "https://feoval.fr/519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4


  



  return "Segmentation fault"

  



  I have the same error on my computer and on AWS Lambda server

  



  ./ffmpeg -i "https://feoval.fr/519.mp4" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4


  



  work (but not watermak)

  



  ./ffmpeg -i "./519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4


  



  work (but not with stream)

  



  Thanks you very much !

• Is there any way that I can speed up the ffmpeg processing time

  20 mai 2020, par Ahmed Al-Rayan

  I am facing a problem with the processing process. I use a real joint server in a digital hosting package of $ 10 and use cloud service from Amazon s3. The problem is when uploading a video, whatever the size of the video, whether its size is 1 megabyte or 2 Giga. After the upload process, the processing process starts to upload, there is no problem But when the processing process takes a very long time so that I cannot complete it, what is the solution to that, is there a problem for me or is this process normal ?
 I use laravel-ffmpeg and through laravel queue I am cutting the video into several qualities I will attach the code to you below.

  



  public function handle()
{
    //180p
    $lowBitrate1 = (new X264('aac'))->setKiloBitrate(613);
    //270p
    $lowBitrate2 = (new X264('aac'))->setKiloBitrate(906);
    //360p
    $midBitrate1 = (new X264('aac'))->setKiloBitrate(1687);
    //540p
    $midBitrate2 = (new X264('aac'))->setKiloBitrate(2227);
    //720p
    $highBitrate1 = (new X264('aac'))->setKiloBitrate(4300);
    //1080
    $highBitrate2 = (new X264('aac'))->setKiloBitrate(7917);

FFMpeg::fromDisk('s3')
    ->open($this->movie->path)
    ->exportForHLS()
    ->onProgress(function ($percent) {
        $this->movie->update([
            'percent' => $percent
        ]);
    })
    ->setSegmentLength(10)// optional
    ->addFormat($lowBitrate1)
    ->addFormat($lowBitrate2)
    ->addFormat($midBitrate1)
    ->addFormat($midBitrate2)
    ->addFormat($highBitrate1)
    ->addFormat($highBitrate2)
    ->toDisk('s3')
    ->save("public/Movies/{$this->movie->id}/{$this->movie->id}.m3u8");
}//end of handle
