Under Web Protection -> Application Control enable Network Visibility. Create a new Application control rule, and in "Control these Applications" select "Streaming Media" category and choose apps that you want to block.
For example, this would be a rule that blocks Youtube streaming with "Youtube" and "Google Video" application definitions.
