• Transcoding with the GCP Transcoder API results in a time gap

  3 mars 2021, par banyan

  I've been trying GCP's Transcoder API and having trouble with the time randomly becoming shorter than specified in certain cases.

  


  The specific cases are as follows :

  


  

  1. Specifying startTimeOffset and endTimeOffset (cut off 2 seconds before and after the video)

  


  2. fMP4 is used as container

  


  3. input video is mp4 with screen recording on iPad Pro

  


  


  For example, if I don't specify startTimeOffset and endTimeOffset, the time will not be shortened. Also, there is no problem when MPEG2-TS is specified for container. There may be a problem with the video itself, but I haven't found a clue how to set it up.

  


  I'm not sure whether this is a problem with the Transcoder API or with me.

  


  The test input video : https://gofile.io/d/DUT9rr

  The following is a ffprobe of the resulting manifest file, which is 2 seconds shorter than specified. (expected : 00:02:47.00, actual : 00:02:45.00) In this case, it's a 2-second gap, but it can be 10 seconds or 30 seconds, and it varies from video to video.

• 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.

  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)
