Roku's information about setting up a Channel for Search contains this statement:
We retrieve our video feed from Vimeo, using their Showcase feature and Roku actually says Vimeo is one of the resources that can be used to build a Roku channel. But, the Vimeo feed is formatted as a JSON string (that's controlled by Vimeo and there appears to be no ability to choose an XML formatted feed).
However, the feed_validator that Roku uses requires a URL pointing to an XML-formatted feed (see statement above and follow the link to the Roku feed_validator).
How is one supposed to validate a Vimeo-based channel for Search given this situation?
