Adding Metadata to MP4 Files

We test video playback on a variety of devices, from Mac and Windows PCs, to all the various mobile phone platforms available today. One critical issue that comes up often is that the hosting server has not set the MIME types for the video type. A typical error message for this would be "unknown application/octet-stream". Here is a list of many common formats we encounter.

IMPORTANT: You will need to configure your ftp server to these MIME types for them to be properly recognized by their respective playback devices.

The following types of metadata are allowed to be added for the following formats: 3gp, appletv, fl9, iphone, ipod, m4a, mp4, wmv, zune.

Please note that the length of metatag value can't be greater than 256 characters. This functionality is only supported via AP.
