я новый разработчик Android, мне нужно только создать файл m3u8. Из них поддерживается только mp4. Если вы знаете, дайте мне знать. Я попробовал и увидел, что у меня не было потоковой передачи m3u8.mp4 только работа m3u8 не работала

этот URL-адрес потоковой передачи m3u8

MP4_URI = Uri.разбор(«http://7starcloud.com:1935/live/kalvichanne/chunklist_w999227517.m3u8»);
