• FFMPEG conversion (h.264) taking long time for short videos

  15 février 2023, par Sara

  I am trying to record the video and upload into the aws s3 server. Vuejs as front end and php Laravel as backend, I was not using any conversion before saving it to s3. Due to this if any recording recorded from android cannot be played in apple device due to some codecs..
To over come this, I am using ffmpeg to encode in X264() format to make it play in apple and android device regardless on which device the recording is done.

  


  1 min video taking 6-7 minutes using ffmpeg. I thought may be aws s3 taking time to save, i commented "saving to s3 bucket code" still very slow to save temp public folder in php.

  


  please check the code if i am missing anything to make conversion quick. if any solution update answer with reference link or code snippet with reference to my code below.

  


  public function video_upload(Request $request)
    {
                // Response Declaration   
                $response=array();
                $response_code = 200;
                $response['status'] = false;
                $response['data'] = [];
                // Validation
                // TODO: Specify mimes:mp4,webm,ogg etc 
                $validator = Validator::make(
                $request->all(), [
                'file' => 'required'
                ]
                );
                if ($validator->fails()) {
                $response['data']['validator'] = $validator->errors();
                return response()->json($response);
                }
                try{
                    $file = $request->file('file');
                    //convert
                    $ffmpeg = FFMpeg\FFMpeg::create();
                    $video = $ffmpeg->open($file);
                    $format = new X264(); 
                    //end convert
                    $file_name =  str_replace (' ', '-', Hash::make(time()));
                    $file_name = preg_replace('/[^A-Za-z0-9\-]/', '',$file_name).'.mp4';
                    
                    $video->save($format, $file_name);
                    $file_folder = 'uploads/video/';
                    // Store the file to S3
                    
                    // $store = Storage::disk('s3')->put($file_folder.$file_name, file_get_contents($file));
                    $store = Storage::disk('s3')->put($file_folder.$file_name, file_get_contents($file_name));
                    if($store){
                        // Replace old file if exist
                        //delete the file from public folder
                        $file = public_path($file_name);
                        if (file_exists($file)) {
                            unlink($file);
                        }

                        if(isset($request->old_file)){
 
                            if(Storage::disk('s3')->exists($file_folder.basename($request->old_file))) {
                                 Storage::disk('s3')->delete($file_folder.basename($request->old_file));
                            }
                        }
                    }
                    $response['status'] = true;
                    $response['data']= '/s3/'.$file_folder. $file_name;

                }catch (\Exception $e) {
                    $response['data']['message']=$e->getMessage()."line".$e->getLine();
                    $response_code = 400;
                }
                return response()->json($response, $response_code);
    }


  


  Its blocking point for me. I cannot let user to wait 5-6 mins to upload 1 min video.

  


• Combining audio file and image with ffmpeg in python

  6 octobre 2018, par Liam

  tl ;dr : how to use a bash ffmpeg command in python

  So I’m trying to take one JPEG image and an audio file as input and generate a video file of the same duration as the audio file (by stretching the still image for the whole duration).

  So, I found these :
  https://superuser.com/questions/1041816/combine-one-image-one-audio-file-to-make-one-video-using-ffmpeg

  So, I now have the code for the merging :
  ffmpeg -loop 1 -i image.jpg -i audio.wav -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest out.mp4

  Then I want to use that in python but unable to figure out how to port this to ffmpeg-python or ffpy.

  I found this : Combining an audio file with video file in python

  So, I tried the same thing as him :

  cmd = 'ffmpeg -loop 1 -i image.jpg -i message.mp3 -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest out.mp4'
  
  subprocess.check_output(cmd, shell=True) 
  
  subprocess.call(cmd, shell=True)

  But I got "returned non-zero exit status 1". So what did I do wrong ?

  I am trying to compile Xuggler for Raspberry Pi(Running on Debian OS aka Raspbian),

  I followed the ’Basic Build Instructions’ available here for compiling Xuggler.

  After I successfully installed all the prerequisites and set the correct paths, I ran the following command :

  ant run-tests

  After sometime I am facing the following error and the ant build fails :
