我的网站电影在所有浏览器中播放都很好，但IOS（iPhone和iPad）都有奇怪的行为。 （我无法在其他设备/移动系统中进行测试。）视频随海报一起出现。在触摸播放按钮时，虽然需要片刻响应，但它前进到电影的第一帧并且视频停止;然而，音频继续。如果您触摸屏幕并向前擦除视频，它将开始播放应有的状态。如果然后将其擦回到开头，则行为将重复：声音，但在第一帧之前没有视频，直到向前手动擦除它为止。

在关闭body标签之前：

我在发布之前用两个不同的转换器仔细检查了.mp4文件，并将其正确转换为h264。在我的代码中，我确实将.m4v的类型设置为.mp4。如果我更改它，则没有播放按钮，视频根本无法播放。
我将不胜感激。

我听了一段时间，停止了MAC支持新版本的FLASH。 mimeType：application / x-shockwave-flash 然后我留下一些支持线来验证mimeType，mimetype的版本以及支持浏览器的所有音频和视频CODEC。
