Adds new documentation and environment examples, refactors the YouTube-only flow into backend/services/rtmpStreaming.service.js (start/stop, status, health, chunk processing), updates backend/controllers/youtubeController.js to accept/validate a platform parameter, and integrates frontend support (RTMPLiveModal, rtmp.api, StudioRoomComplete) with start/stop API calls and user toasts. Also updates frontend .env.example with Twitch/Facebook RTMP URLs and includes testing/deployment guidance in new docs (CONTRIBUTION_SUMMARY.md, NEXT_STEPS.md, RTMP_STREAMING_FEATURE.md). Ensure env variables for VITE_* and backend RTMP URLs are set and FFmpeg is available on the server. --- CONTRIBUTION_SUMMARY.md | 123 +++++++++ NEXT_STEPS.md | 220 +++++++++++++++ RTMP_STREAMING_FEATURE.md | 256 ++++++++++++++++++ backend/controllers/youtubeController.js | 14 +- backend/services/rtmpStreaming.service.js | 44 +++ frontend/.env.example | 8 +- frontend/src/api/rtmp.api.js | 3 +- .../components/Main/StudioRoomComplete.jsx | 44 ++- .../src/components/studio/RTMPLiveModal.jsx | 6 +- 9 files changed, 704 insertions(+), 14 deletions(-) create mode 100644 CONTRIBUTION_SUMMARY.md create mode 100644 NEXT_STEPS.md create mode 100644 RTMP_STREAMING_FEATURE.md diff --git a/CONTRIBUTION_SUMMARY.md b/CONTRIBUTION_SUMMARY.md new file mode 100644 index 0000000..40af8d6 --- /dev/null +++ b/CONTRIBUTION_SUMMARY.md @@ -0,0 +1,123 @@ +# Contribution Summary: Multi-Platform RTMP Streaming + +## 🎯 Feature Overview +Implemented multi-platform live streaming support for FinalCast, enabling users to broadcast their studio sessions to YouTube, Twitch, and Facebook Live simultaneously from a single interface. + +## 📦 What Was Delivered + +### Backend Implementation +✅ **Generic RTMP Streaming Service** -
