• Safari on Mac and IOS 14 Won't Play HTML 5 MP4 Video

  10 mars 2021, par Glen Elkins

  So i have developed a chat application that uses node for the back-end. When a user selects a video on their iphone it usually is .mov format so when it's sent to the node server it's then converted to mp4 with ffmpeg. All that works fine, then if i load up my chat again in Chrome on my mac the video plays just fine as the mp4.

  


  

  


  This screenshot shows the video embed is there, set to mp4 yet it won't play in Safari on my mac or my phone, in fact it just shows the video as 0 seconds long yet i can play it in chrome and also download the mp4 file by accessing the embed url directly.

  


  Any ideas ? I had it convert to mp4 to prevent things like this, but safari doesn't seem to even like mp4 files.

  


  The back-end part that serves the private file is in Symfony 4 (PHP) :

  


  /**
     * @Route("/private/files/download/{base64Path}", name="downloadFile")
     * @param string $base64Path
     * @param Request $request
     * @return Response
     */
    public function downloadFile(string $base64Path, Request $request) : Response
    {


        // get token
        if(!$token = $request->query->get('token')){
            return new Response('Access Denied',403);
        }



        /** @var UserRepository $userRepo */
        $userRepo = $this->getDoctrine()->getRepository(User::class);

        /** @var User $user */
        if(!$user = $userRepo->findOneBy(['deleted'=>false,'active'=>true,'systemUser'=>false,'apiKey'=>$token])){
            return new Response('Access Denied',403);
        }



        // get path
        if($path = base64_decode($base64Path)){

            // make sure the folder we need exists
            $fullPath = $this->getParameter('private_upload_folder') . '/' . $path;



            if(!file_exists($fullPath)){
                return new Response('File Not Found',404);
            }

        

            $response = new Response();
            $response->headers->set('Content-Type', mime_content_type($fullPath));
            $response->headers->set('Content-Disposition', 'inline; filename="' . basename($fullPath) . '"');
            $response->headers->set('Content-Length', filesize($fullPath));
            $response->headers->set('Pragma', "no-cache");
            $response->headers->set('Expires', "0");
            $response->headers->set('Content-Transfer-Encoding', "binary");

            $response->sendHeaders();

            $response->setContent(readfile($fullPath));

            return $response;
        }

        return new Response('Invalid Path',404);
    }


  


  This works fine everywhere except safari when trying to embed the video. It's done like this because the videos are not public and need an access token.

  


  UPDATE : Here is a test link of an mp4, you'll have to allow the insecure certificate as it's on a quick test sub domain. If you open it in chrome, you'll see a 3 second video of my 3d printer curing station, if you load the same link in safari, you'll see it doesn't work

  The server runs on cPanel with Apache and i think it might be something to do with the video needs streaming ?

  


  UPDATED CODE THAT WORKS IN SAFARI BUT NOW BROKEN IN CHROME :

  


  Chrome is now giving Content-Length : 0 but it's working fine in safari.

  


  public function downloadFile(string $base64Path, Request $request) : ?Response

            }


            $filesize = filesize($fullPath);
            $mime = mime_content_type($fullPath);

            header('Content-Type: ' . $mime);

            if(isset($_SERVER['HTTP_RANGE'])){

                // Parse the range header to get the byte offset
                $ranges = array_map(
                    'intval', // Parse the parts into integer
                    explode(
                        '-', // The range separator
                        substr($_SERVER['HTTP_RANGE'], 6) // Skip the `bytes=` part of the header
                    )
                );



                // If the last range param is empty, it means the EOF (End of File)
                if(!$ranges[1]){
                    $ranges[1] = $filesize - 1;
                }

                header('HTTP/1.1 206 Partial Content');
                header('Accept-Ranges: bytes');
                header('Content-Length: ' . ($ranges[1] - $ranges[0])); // The size of the range

                    )
                );

                // It's time to output the file
                $f = fopen($fullPath, 'rb'); // Open the file in binary mode
                $chunkSize = 8192; // The size of each chunk to output

                // Seek to the requested start range
                fseek($f, $ranges[0]);

                // Start outputting the data
                while(true){
                    // Check if we have outputted all the data requested
                    if(ftell($f) >= $ranges[1]){
                        break;
                    }

                    // Output the data
                    echo fread($f, $chunkSize);

                    // Flush the buffer immediately
                    @ob_flush();
                    flush();
                }
            }else{

                // It's not a range request, output the file anyway
                header('Content-Length: ' . $filesize);

                // Read the file
                @readfile($filesize);

                // and flush the buffer
                @ob_flush();
                flush();



            }

        }else {

            return new Response('Invalid Path', 404);
        }
    }


  


  I have notice in chrome that it's sending the range header like this :

  


  Range : bytes=611609-

  


  Where safari sends

  


  Range : bytes=611609-61160

  


  So for some reason chrome is missing the second range amount, that obviously means my code can't find a range number for the second one.

  


  Doesn’t matter what I do I can’t get it working in both chrome and safari. Safari wants the byte range part , chrome seems to request it then sends a new request for the full file but even the full file part of the code gives a 500 error. If I take out the byte range bit then it works fine in chrome but not safari.

  


  UPDATE :

  


  Here is some strange things going on in chrome :

  


  For the video i am testing with it makes 3 range requests :

  


  REQUEST 1 HEADERS - asking for bytes 0- (to the end of the file)

• Decoding Video using FFMpeg for android

  29 novembre 2014, par Rahul Upadhyay

  I tried to decode video using FFMpeg library from the sample examples available on internet, i figure it out with new version of ffmpeg,
  here is the code which I called from my class file,

     private static native int decodeVideo(String filename);
  
     decodeVideo(getString(R.string._sdcard_abc_3gp));

  now in .c file located in JNI dir,I wrote this code,

   jint Java_ru_dzakhov_ffmpeg_test_MainActivity_decodeVideo(JNIEnv* env, jobject
  
  javaThis,jstring filename) {   
  
    AVFormatContext *pFormatCtx;

  Unable to understand what’s exact problem is there ?
  Here SaveFrame function is used it looks like,

  void SaveFrame(AVFrame *pFrame, int width, int height, int iFrame) {
  
    FILE *pFile;
  
    char szFilename[32];
  
    int  y;
  
  
  
    // Open file
  
    LOGI("Opening file!");
  
    sprintf(szFilename, "frame%d.ppm", iFrame);
  
  
  
    pFile=fopen(szFilename, "wb");
  
    if(pFile==NULL)
  
      return;
  
  
  
    // Write header
  
    fprintf(pFile, "P6\n%d %d\n255\n", width, height);
  
    //LOGI("width::"+width+"Height::"+height);
  
    // Write pixel data
  
    for(y=0; ydata[0]+y*pFrame->linesize[0], 1, width*3, pFile);
  
    }
  
    // Close file
  
    fclose(pFile);
  
  }

  in log I didn’t get any Log which i placed in the code !

  Please help me out,

  Thanks
