Does Cloud Live support video playback?

说明与用途

在摄像头平台中将实时流和回放路径分离，可消除 UI 混淆，确保正确权限，并简化未来功能扩展。

问题

Developers need to distinguish between live streaming and playback in a camera platform, ensuring correct API routes, UI behavior, and permissions.

结果

Clear separation of live and playback paths prevents UI confusion, enforces correct permissions, and simplifies future feature expansion.

工作流

• 1. Design separate API routes for live and playback.
• 2. Add capability flag cameras.capabilities.playback to indicate recording availability.
• 3. Implement RBAC helper with distinct permission keys for live and playback.
• 4. On Day 1 ship live-only tile without timeline UI.
• 5. On Day 2 expose capability row showing playback:false until source available.
• 6. On Day 3 add playback route with proper error handling (no_source, empty).
• 7. On Day 4 handle empty range with empty state UI.
• 8. On Day 5 ensure teardown destroys player before switching modes.
• 9. Create mediaGateway with openLive, openPlayback, capabilities methods.
• 10. Write unit tests for all edge cases (flags, permissions, empty ranges, navigation, clock skew).

证据

I refuse a single openVideo(). I have shipped that function. It always grows a mode argument and a comment that says “TODO timeline.”

If product asks for “video,” I ask which word they meant.
