HTTP-ответ Laravel 5, файлы M4V и iOS MPMoviePlayerViewController

Я знаю, что это старый пост, но в итоге мне пришлось транслировать видео в Laravel с S3 на плеер, который требовал поддержки HTTP_RANGE. Я положил это вместе (после прочтения многих тем). Это должен Поддержите все диски (), которые вы определили в Laravel.

Я использовал класс ниже, размещенный в App / Http / Responses. Чтобы использовать этот класс, создайте метод, который делает это (это будет содержимым вашего метода getFile):

$filestream = new \App\Http\Responses\S3FileStream('file_path_and_name_within_bucket', 'disk_bucket_name');
return $filestream->output();

Я только что указал src моего видеоплеера на путь для этого метода и успеха!
