推荐答案
首先加载页面然后按F12打开开发人员工具，然后弹出在控制台的控制台选项卡中，使用下面的脚本获取对视频对象的引用（如果视频元素不是第一个视频元素，则需要调整数组值）。
First load up the page and press F12 to bring up the developer tools , then pop over to the console tab in the console , get reference to the video object using the script below (If the video element is not the first video element then you will need to adjust the array value ).
document.getElementsByTagName（video）[0] .error.code
返回的代码让你知道出了什么问题，
document.getElementsByTagName("video")[0].error.code The code that is returned let you know what’s gone wrong,
MEDIA_ERR_ABORTED：1
用户中止了媒体资源的提取过程。
MEDIA_ERR_DECODE：3
在资源建立可用之后，媒体资源的解码出错。
MEDIA_ERR_NETWORK：2
在资源建立可用后，网络错误导致用户代理停止获取媒体资源
MEDIA_ERR_SRC_NOT_SUPPORTED：4
指定的媒体资源src无法使用。
在IE9中，如果您收到错误代码4，则有两个常见问题：
MEDIA_ERR_ABORTED : 1 The fetching process for the media resource was aborted by the user. MEDIA_ERR_DECODE : 3 An error has occurred in the decoding of the media resource, after the resource was established to be usable. MEDIA_ERR_NETWORK : 2 A network error has caused the user agent to stop fetching the media resource, after the resource was established to be usable MEDIA_ERR_SRC_NOT_SUPPORTED : 4 The media resource specified by src was not usable. In IE9 if you get error code 4 then there are two common issues:
错误编码
如果用户在其计算机上安装了编解码器，则IE9在MP4容器和WebM中支持H.264。要支持IE9，您需要确保已正确编码视频。对于H.264视频，我使用Miro（包装FFMPEG的Windows上的.net应用程序）或者如果我想要特定的基线或设置，我使用Expression Encoder。
IE9 supports H.264 in an MP4 container and WebM if the user has the codec installed on their machine. To support IE9 you will need to ensure that you have correctly encoded your video. For H.264 video I use Miro (a .net application on windows that wraps up FFMPEG) or if I want a specific baseline or setting I use Expression Encoder.
DIRECTORY
您是否将媒体文件放在包含此html的同一目录中？
如果没有，请设置文件的正确路径。
Are you placing the media files in the same directory holding this html? If not, set right path to files.
MIME类型
您需要确保服务器在返回文件时返回正确的MIME类型。如果文件是MP4，则文件MIME类型应为video / mp4。如果要检查MIME类型，请使用F12开发人员工具（在IE9中按F12键），然后导航到网络选项卡。按开始捕获并刷新网站。
You need to make sure your sever returns the correct MIME type when it returns a file. If the file is MP4 then the files MIME type should be video/mp4. If you want to check the MIME type then use the F12 developer tools (press F12 in IE9) and then navigate to the Network Tab. Press Start Capturing and refresh the web site.
