Please note that this would violate the Twitch Developer Services Agreement. Specifically, at the time of this writing, the following is stated under “Embeddable Player” in “Schedule 1.”
If you have an idea that involves distribution of video content outside the Twitch player, or commercial uses not expressly permitted by Twitch, send us a request and we will consider it (integrationsuccess@twitch.tv). Unless we permit it, don’t do it.
