CI Bot	ffed853f6e	fix(worker): FFmpeg 超时保护 - 防止渲染 hang 住导致 worker 永久阻塞 CI/CD Pipeline / Production Browser E2E (pull_request) Failing after 1564h59m36s Details CI/CD Pipeline / Staging API Integration Tests (pull_request) Failing after 1564h59m38s Details CI/CD Pipeline / Staging E2E Tests (pull_request) Failing after 1564h59m38s Details CI/CD Pipeline / Build Production Runtime Images (pull_request) Failing after 1564h59m39s Details CI/CD Pipeline / Build & Push Staging (Watchtower auto-deploy) (pull_request) Failing after 1564h59m39s Details CI/CD Pipeline / Validate Code Quality And Tests (pull_request) Has been skipped Details CI/CD Pipeline / Integration Tests (pull_request) Has been skipped Details CI/CD Pipeline / Frontend Lint (pull_request) Has been skipped Details CI/CD Pipeline / Deploy Production (pull_request) Failing after 1565h31m11s Details 根因：新引擎 UnifiedRenderService 所有 FFmpeg 调用通过 run_ffmpeg 执行，但 subprocess.run 未设置 timeout，FFmpeg hang 住时 worker 线程永久阻塞。旧引擎 compose_video 有单独的 timeout=3600，但新引擎路径没有。修复： 1. run_ffmpeg 新增默认超时 1800s（30分钟），支持自定义传参 2. 捕获 TimeoutExpired 并打 error 日志后重新抛出 3. probe_video_info 新增 timeout=15s 超时保护 4. 7个单元测试覆盖超时逻辑影响范围：所有通过 run_ffmpeg 调用的 FFmpeg 命令（unified_render_service 所有渲染/混音/合并操作）	2026-07-13 10:17:14 +08:00
