[video] Correct mime type for .mp4

I have two applications as mentioned below:

1. Admin application through which I am able to upload a .mp4 file to the server.
2. I am trying to download the .mp4 using mobile application in iPad.

• The Admin application is made by using asp.net 4.0 and SQL Server, IIS7.
• The Mobile application is made of asp.net mvc3, jquerymobile, HTML5.

As of now I have added mime type video/mp4 for .mp4 in IIS7 mime types section.

When I am trying to download the .mp4 file in iPad I am seeing a dark black screen with cross arrow on it. Can anyone please help me to resolve the issue.

Please tell me whether the mime type video/mp4 for .mp4 is correct.

When uploading .mp4 file into Perl script, using CGI.pm I see it as video/mp when printing out Content-type for the uploaded file. I hope it will help someone.

According to http://help.encoding.com/knowledge-base/article/correct-mime-types-for-serving-video-files/, the correct mime type for .mp4 is video/mp4

video/mp4should be used when you have video content in your file. If there is none, but there is audio, you should use audio/mp4. If no audio and no video is used, for instance if the file contains only a subtitle track or a metadata track, the MIME should be application/mp4. Also, as a server, you should try to include the codecs or profiles parameters as defined in RFC6381, as this will help clients determine if they can play the file, prior to downloading it.
