Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

Does anybody have experience in embedding ffmpeg in a macOS application for the App Store ? Has anybody had his application rejected for this reason ?
31 octobre 2020, par Alfonso TesauroI am developing a tool for macOS that needs some basic audio editing, and the simplest way to achieve this is to embed ffmpeg in the application binary and call it with NSTask. Of course, I resigned ffmpeg with my identity and the entitlements to inherit the host application's sandbox. Has anybody tried this with success ? Any help is greatly appreciated. Thanks

Safari on Mac and IOS 14 Won't Play HTML 5 MP4 Video
10 mars 2021, par Glen ElkinsSo 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
 {

 ob_clean();

 // 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);
 }


 $filesize = filesize($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

 // Send the ranges we offered
 header(
 sprintf(
 'Content-Range: bytes %d-%d/%d', // The header format
 $ranges[0], // The start range
 $ranges[1], // The end range
 $filesize // Total size of the file
 )
 );

 // 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)


GET /private/files/download/Y2hhdC83Nzk1Y2U2MC04MDFmLTExZWItYjkzYy1lZjI4ZGYwMDhkOTMubXA0?token=6ab1720bfe922d44208c25f655d61032 HTTP/1.1

RESPONSE GIVES IT BACK ALL THE BYTES IN THE FILE AS THAT'S WHAT WAS ASKED FOR BY CHROME :

Bad conversion video from yuv to rgb using ffmpeg
10 août 2021, par TchaikovicI'm trying to convert a video from YUV to RGB. I'm using ffmpeg for this with the following command line


ffmpeg -y input.mp4 -c:v libx264rgb output.mp4


Unfortunately the output seems somehow corrupted. See example input/output images below. I'm also pasting here the output of mediainfo for both videos. Many thanks in advance for your advices.
