Wrong mime type used in <video> tag for .m4v files

[jrue]

In media.php on line 1080, there is no such thing as video/m4v mime type that can be used in the video tag. This essentially breaks all .m4v files from showing up, regardless of the mime type its delivered with. This should be changed to either video/x-m4v (non standard, but Apple recommended) or more appropriately the standards recommended mime video/mp4.

Apple's .m4v files are essentially mp4 encodes wrapped with a different file extension.

This is the video I'm testing with.

MediaElement checks for video/m4v - the video tag is just a container for whatever ME is going to do to it. I just downloaded your video, it works for me... ​http://cl.ly/image/0r0w0X2C0A17

video/m4v is an alias. No other feedback from reporter in 8 months... closing.
