试试这个：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
<video width="100%" controls>
<source src="data:application/x-mpegURL;base64,..." type="application/x-mpegURL">
</video>
</body>
</html>
@django_newbie 很抱歉，但它也没有那样工作。
