  Encountered error

  Class ’Pbmedia\LaravelFFMpeg\FFMpegServiceProvider\FFMpeg’ not found

  I’m building a web application to upload a video and store it in cloud. I want to get the duration of the uploaded video. I tried to install laravel/FFMpeg package. After doing all the steps, I’m getting the above error.

  Code

  My controller code :

  <?php 
  
  namespace App\Http\Controllers;
  
  use Auth;
  
  use Illuminate\Http\Request;
  
  use DB;
  
  use App\Http\Requests;
  
  use App\Http\Controllers\Controller;
  
  use Illuminate\Support\Facades\Storage;
  
  use App\Providers\DropboxServiceProvider;
  
  use Dropbox\Client;
  
  use Dropbox\WriteMode;
  
  use Pbmedia\LaravelFFMpeg\FFMpegServiceProvider as FFMpeg; 
  
  //use Pbmedia\LaravelFFMpeg\FFMpegFacade as FFMpeg;
  
  //use FFMpeg;
  
  
  
  class FileController extends Controller 
  
  {
  
     public function FileUpload(Request $request)
  
     {
  
      $file = $request->file('file');
  
      $note = $request->input('note');
  
      //$request->file('file')->store('assets');
  
      if($file)
  
      { 
  
  
  
           //Storage::disk('local')->put($file, $file);
  
          //$file = $request->input('file')->store('1.png');
  
           $file1 = Storage::disk('local')->put('' ,$request->file) ;
  
           $filename = $file->getClientOriginalName();
  
  
  
           Storage::move(''.$file1, $filename); // keep the same folder to just rename 
  
  
  
  
  
  
  
           $file = FFMPEG\FFMpeg::open($filename);
  
           $durationInSeconds = $file->getDurationInSeconds();
  
           return view('users/order-status')->with('file',$durationInSeconds);
  
      }
  
      else
  
      {
  
          $file ="not found";
  
      }
  
      return view('users/order-status')->with('file',$file);
  
     }
  
  
  
     public function dropboxFileUpload(Request $request)

          //$file = "/storage/app/".$file. "";
  
  
  
          //dd($path);
  
          //$file = dd($path);

• ffmpeg : drawtext fade in/out with zmq

  11 novembre 2019, par jb_alvarado

  There are several ways to fade in and out text in ffmpeg. But I only found solutions where the actual time is known.

  But what can I do, when I don’t know the current running time and I would like to fade in and out a text ?

  Let’s say I have an endless stream and I want to fade in a text with zmqsend. And the fade should start immediately. For that my understanding is, that I need to store some time information in a variable and calculate with that. But storing variables is not possible in ffmpeg expressions - right ?

  For testing purposes here are a playing instance :

  ffplay -dumpgraph 1 -f lavfi "color=s=512x288:c=black,zmq,drawtext=text=''"

  For adding some text with zmq I can run now :

  echo Parsed_drawtext_2 reinit text="Hello\ World,\ what’s\ up?" | zmqsend

  Or if I know the running time and after 10 seconds I want the text fade in :

  "text='Hello\ World':fontsize=:fontcolor=ffffff:alpha='if(lt(t,10),0,if(lt(t,11),(t-10)/1,if(lt(t,16),1,if(lt(t,17),(1-(t-16))/1,0))))'"

  My goal is now to have an expression what I can send, so that ffmpeg starts fading in the text and out after a certain time.

  Something like :

  now=t,if(lt(t,now+10),0,if(lt(t,now+11),(t-(now+10))/1,if(lt(t,now+16),1,if(lt(t,now+17),(1-(t-(now+16)))/1,0))))

  Is there a way to store variables in expression, or is there any other way to realize this ?

• ffmpeg and 64 bit architecure

  16 avril 2015, par nevgauker

  there is a pretty old project i need to upload to the store.
  how old you ask ? 32 bit only ,no arc and no story board...

  since in this days in mandatory to make a single archive that support 32 and 64 build ...i decided to update the valid architecture of the project.
  i discovered that many frameworks do not support 64 bit and i have to update them . the most problematic is ffmpge..
  here i few things that i tried to do and fail :

  1. add ffmpeg as a static libary
  2. add ffmpeg using cocoa pods

  nothing helps...

  here are some of the errors i get :
  Undefined symbols for architecture arm64 :
  "_av_read_frame", referenced from :
  -[Demuxer readPacket :] in Demuxer.o
  "_av_malloc", referenced from :
  -[Streamer writePacket :] in Streamer.o
  "_av_register_all", referenced from :
  +[Streamer initialize] in Streamer.o
  "_avformat_write_header", referenced from :
  -[Streamer writePacket :] in Streamer.o
  "_avio_close", referenced from :
  -[Streamer dealloc] in Streamer.o
  "_av_new_stream", referenced from :
  -[Streamer writePacket :] in Streamer.o
  "_avformat_free_context", referenced from :
  -[Streamer dealloc] in Streamer.o

  any suggestion ?

  the only way i succeed is turn on the "build active architecture only" (and of course get rejected when i try to upload to the store)

  if you refer me to any shell script, please instruct me how to use it

  thanks
