How can PHP scripts be optimized to directly open .mkv URLs in media players like VLC without temporary storage?

To directly open .mkv URLs in media players like VLC without temporary storage, you can use PHP to generate a playlist file (.m3u) containing the URL of the .mkv file. This playlist file can then be opened by VLC to stream the video directly from the URL.

<?php
$mkvUrl = 'http://example.com/video.mkv';
$playlistContent = "#EXTM3U\n#EXTINF:-1,$mkvUrl";
$playlistFile = 'playlist.m3u';

file_put_contents($playlistFile, $playlistContent);

header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . $playlistFile . '"');
readfile($playlistFile);

unlink($playlistFile);
?>
