Как ускорить, чтобы играть песню, как Джио Саван и Ганна

Question

Я сделал Musi c сайт, URL-адрес которого это https://www.j-esho.conqrapp.com/

Когда я пытаюсь воспроизвести песню из браузера Safari, требуется время для воспроизведения.

Но Джио Саван и Ганна играют музыку c быстрее, чем наш сайт.

Что мне нужно для этого сделать.

Для потокового чанка в качестве ответа я сделал это.

функция serveFilePartial ($ fileName, $ fileTitle = null, $ contentType = 'application / octet-stream') {if (! File_exists ($ fileName)) генерирует New \ Exception (sprintf ('Файл не найден:% s ', $ fileName));

if( !is_readable($fileName) )
    throw New \Exception(sprintf('File not readable: %s', $fileName));


### Remove headers that might unnecessarily clutter up the output
header_remove('Cache-Control');
header_remove('Pragma');


### Default to send entire file
$byteOffset = 0;
$byteLength = $fileSize = filesize($fileName);

header('Accept-Ranges: bytes', true);
header(sprintf('Content-Type: %s', $contentType), true);

if( $fileTitle )
    //header(sprintf('Content-Disposition: attachment; filename="%s"', $fileTitle));

### Parse Content-Range header for byte offsets, looks like "bytes=11525-" OR "bytes=11525-12451"
if( isset($_SERVER['HTTP_RANGE']) && preg_match('%bytes=(\d+)-(\d+)?%i', $_SERVER['HTTP_RANGE'], $match) )
{
    ### Offset signifies where we should begin to read the file
    $byteOffset = (int)$match[1];


    ### Length is for how long we should read the file according to the browser, and can never go beyond the file size
    if( isset($match[2]) ){
        $finishBytes = (int)$match[2];
            $byteLength = $finishBytes + 1;
    } else {
        $finishBytes = $fileSize - 1;
    }

    $cr_header = sprintf('Content-Range: bytes %d-%d/%d', $byteOffset, $finishBytes, $fileSize);

    header("HTTP/1.1 206 Partial content");
    header($cr_header);  ### Decrease by 1 on byte-length since this definition is zero-based index of bytes being sent
}

$byteRange = $byteLength - $byteOffset;

header(sprintf('Content-Length: %d', $byteRange));

header(sprintf('Expires: %s', date('D, d M Y H:i:s', time() + 60*60*24*90) . ' GMT'));


$buffer = '';   ### Variable containing the buffer
$bufferSize = 512 * 16; ### Just a reasonable buffer size
$bytePool = $byteRange; ### Contains how much is left to read of the byteRange

if( !$handle = fopen($fileName, 'r') )
    throw New \Exception(sprintf("Could not get handle for file %s", $fileName));

if( fseek($handle, $byteOffset, SEEK_SET) == -1 )
    throw New \Exception(sprintf("Could not seek to byte offset %d", $byteOffset));


while( $bytePool > 0 )
{
    $chunkSizeRequested = min($bufferSize, $bytePool); ### How many bytes we request on this iteration

    ### Try readin $chunkSizeRequested bytes from $handle and put data in $buffer
    $buffer = fread($handle, $chunkSizeRequested);

    ### Store how many bytes were actually read
    $chunkSizeActual = strlen($buffer);

    ### If we didn't get any bytes that means something unexpected has happened since $bytePool should be zero already
    if( $chunkSizeActual == 0 )
    {
        ### For production servers this should go in your php error log, since it will break the output
        trigger_error('Chunksize became 0', E_USER_WARNING);
        break;
    }

    ### Decrease byte pool with amount of bytes that were read during this iteration
    $bytePool -= $chunkSizeActual;

    ### Write the buffer to output
    print $buffer;

    ### Try to output the data to the client immediately
    flush();
}

exit();
