Hi @hs08 ,
Not all devices are supporting it, but you could use NBAR2 data, that are part of NetFlow (https://documentation.solarwinds.com/en/success_center/nta/content/nta-applications-nbar2.htm). In the Cisco NBAR2 list of defined applications is directly specified "youtube" https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_nbar/prot_lib/protocol-reference/nbar-protocol-reference/y.html#protocol-youtube.
