修复线上视频导出卡死(OOM)+ 导出健壮性加固
根因:后端容器内存 limit 仅 768Mi,ffmpeg 编码 1080P 竖屏时内存峰值超限被 K8s OOMKill,导出后台线程随 Pod 重启而死,任务永远停在 35%(本地无 limit 29s 出片)。 - k8s/core/api-deployment.yaml: 后端内存 limit 768Mi→2Gi、requests 256→512Mi, 给 ffmpeg 足够编码空间(根治) - export.py: ffmpeg subprocess 加 900s 超时(卡死不再永久 RUNNING)+ -threads 2 降内存峰值 - views.py: submit-export 清理超 5 分钟未结束的僵尸任务,前端不再无限转圈 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
