I debug browser live cameras in this order: ACL, mount, then the network tab

说明与用途

浏览器中实时摄像头流的逐步调试工作流程，涵盖 ACL 检查、播放器挂载和会话生命周期管理。

问题

Live IP camera streams appear black or fail in web apps due to permission, mounting, or session lifecycle issues.

结果

A repeatable, browser‑compatible debugging workflow that reduces time to identify ACL, mounting, and session lifecycle issues in live camera streams.

工作流

• List cameras via tenant‑scoped API
• User clicks Watch
• POST /live to check role and capability
• Handle 403/409/other errors
• Receive session object
• Mount player with player.mount(el).play()
• Implement cleanup in unmount (destroy)
• Use AbortController to cancel fetch on unmount
• Check network panel order: POST status, media/websocket start, cancellation, race conditions
• Test on Chrome, Safari iOS, Firefox
• Use local mocks to simulate 403/409 and session responses
• Pin player package and test teardown
• Turn off console logs in production

来源

List cameras from my API (tenant scoped).

Abort the fetch and destroy the player. One or the other is how races sneak through.
