Replace the crossOrigin prop (which mapped HTML video element values to fetch credentials) with a direct credentials: RequestCredentials prop. Thread credentials through getSinks/getSink and document the new prop. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
… Audio Pass credentials prop through extractFrame, extractAudio, extractFrameAndAudio, extractFrameViaBroadcastChannel, and the broadcast channel request type. Add credentials to AudioProps and audio-for-preview. Add AvailableFrom tag to Video docs and add credentials documentation for Audio. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
