  One more thing..As of now I am trying to cross-compile ffmpeg on ubuntu,But If I just compile it for linux..The same command doesnt gives any error and executes smoothly and then I am able to get ffmpeg with aacplus support for my linux machine, But why the problem is coming when I am cross compiling it.

  Another thing as aacplus is not on by default, If in configuration I dont put any (off by default) library support like if I remove aacplus from it, Then also it goes smoothly.

  Help please ASAP

• crossorigin header in php is not working after previous php exec ffmpeg command

  17 avril 2022, par ivyyeziyang

  I am using php exec function to execute a FFMPEG command, but I am also using Javascript to send the request and they are cross origin requests, but after the exec command, while I start to send next cross origin request, it shows
Access to XMLHttpRequest at 'https://www..com:550/api/adminapi' from origin 'https://www..com:8081' has been blocked by CORS policy : No 'Access-Control-Allow-Origin' header is present on the requested resource.
which means the cross origin header is not working in the next cross origin request after exec command,
below is the code :

  


  if (isset($_POST['crossorigin'])) {
$crossoriginallow = array();
$crossoriginallow = [
'https://www.***.com:8080', 
'https://www.***.com:8081', 
'https://www.***.com:8082'];
for ($i = 0; $i < sizeof($crossoriginallow); $i++) {
if ($crossoriginallow[$i] == $_POST['crossorigin']) {
  $crossorigin = $_POST['crossorigin'];
  break;
  }
}
header("Access-Control-Allow-Origin:$crossorigin");
header("Access-Control-Allow-Methods:GET, POST, OPTIONS, DELETE");
header("Access-Control-Allow-Headers:DNT,X-Mx-ReqToken,Keep- 
Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache- 
Control,Content-Type, Accept-Language, Origin, Accept-Encoding");
}

exec("ffmpeg -i " . $infilepath . " -c:v mpeg4 -preset veryslow - 
 c:a mp3 -q 0 " . $outfilepath /* . " 2>&1" *//* , $out */);

 $infilepathsep = explode('/', $infilepath);
 $folderpath = '';
 for ($i = 0; $i < sizeof($infilepathsep) - 1; $i++) {
 $folderpath = $folderpath . $infilepathsep[$i];
 $folderpath = $folderpath . '/';
}

 $opendirhandle = opendir($folderpath);
 closedir($opendirhandle);
 $openfilehandle = fopen($infilepath, 'r');
 fclose($openfilehandle);
 unlink(iconv("utf-8", "gbk", $infilepath));
 $result['data'] = $outfilepath;
 $result['msg'] = 'success';
 $jsonresult = json_encode($result);
 echo $jsonresult;
 ob_get_contents();
 ob_end_flush();


  


  I does not encounter this problem before using the same code,but after I reinstall the computer it happens, May I please ask the reason if you know the problem ? Thank you very much for your help !
