Description

Attached file are .wmv file (ASF Container) with a video tracks encoded using the WMV2 codec. They are incorrectly detected as audio (audio/x-ms-wma) file instead of video (video/x-ms-wmv) file. 

Adding the following line to the tiki-mimetypes.xml file fixes the issue:

    <match value="wmv2" type="unicodeLE" offset="0:8192" />
