Check if a MIME Part is Video

Demonstrates the Chilkat Mime.IsVideo method, which returns whether the Content-Type begins with video/. It takes no arguments and applies to the current part.

Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own file.

Background: The video counterpart to the other media predicates, for identifying video attachments so they can be treated appropriately — extracted, transcoded, or size-checked. It matches any video/ subtype.
