npm run devYouTube Live creation uses the YouTube Data API and Google OAuth for desktop apps. OpenStream requires a Google OAuth desktop client ID and client secret at build time. Users still sign in with their own Google account.
For local development, put the values in a local .env file. This file is ignored by git:
cp .env.example .env
# edit .env and set:
# YOUTUBE_CLIENT_ID="your-google-oauth-client-id"
# YOUTUBE_CLIENT_SECRET="your-google-oauth-client-secret"
npm run devLocal production builds use the same .env file and embed the values into the Electron main bundle:
npm run buildContributions are welcome - please include screenshots or a short video for any UI change or new user-facing feature. If it touches what users see or do, show it. Skip only when it genuinely doesn't apply. PRs that don't follow this will be closed.
OpenStream needs screen capture permission to detect and stream screens or windows. Microphone and camera permissions are required only when those inputs are enabled.
