Add MIME mappings for IIS Publishing

The test release encountered a small problem, involving the previous no contact issues, recorded.

Background: Features require that video be called from the server, enabling the ability to browse videos in a Web page.

Problem: Your own video is ". mkv" format, after the call from the background, it is not normal to play, error prompts as follows:

After checking to find that the HTML multimedia tag you used was not an error, later, according to the page hints, you can configure the MIME type of IIS to enable the browser to play ". mkv" format video. The process is simple:

So set the original browser (Firefox, Google) can not play the problem is resolved.

Summary: Later after a number of tests found not to be effective, some format of video or audio can not be configured by the MIME type to solve, because of the browser's own conditions based on the configuration factors, non-human can be changed. Different browsers have different support standards for different multimedia:

MIME type Popular:

MIME is intended to be a multi-mesh Internet Mail extension designed to append multimedia data when sending e-mail, allowing mail clients to process according to their type. However, when it is supported by the HTTP protocol, its meaning is even more pronounced.  It makes the HTTP transfer not only the ordinary text, but also become colorful. Each MIME type consists of two parts, preceded by a large category of data, such as audio audio, image image, and so on, followed by a specific category.

Personal understanding: The browser according to MIME type to interpret the accepted file, what kind of file needs what kind of mime type, otherwise the browser is not recognized, the current understanding is this.
