From 4513f82fb126c14048e2d9ad4bec9995682f781f Mon Sep 17 00:00:00 2001 From: saas-backend-agent Date: Tue, 8 Sep 2026 12:49:09 +0800 Subject: [PATCH 1/3]

从 title_config 生成 FFmpeg drawtext 滤镜 - 支持 position(top/center/bottom/custom+pos_x/pos_y) - 支持 font_size/font_color/bold/stroke/shadow - 字段名归一化：兼容 content↔text、font_preset↔font、size↔font_size、color↔font_color - 特殊字符转义（:/'%） - 字体搜索路径（Noto Sans CJK 优先） 在 video_compose_service.py build_compose_command() 集成： - 从 plan.config 读取 title_config（兼容 title/title_config 两个 key） - drawtext 滤镜链入 filter_complex（[composed]→drawtext→[outv]） - 单视频和批量生成共用同一 compose 路径，标题都能生效 26 新测试覆盖：基本参数/位置/样式/字段归一化/特殊字符转义/输出尺寸 ---
