xiaoxia	4657ededfe	feat(worker): 参考视频风格分析模块 video_analyzer (#2051) ... 实现 v1.3 爆款视频参考风格分析 6 步管线： ① FFmpeg 抽关键帧（每 2s 一帧 + 场景切换帧） ② PySceneDetect ContentDetector(threshold=27) 镜头分割 ③ OpenCV Farneback 光流运镜检测（推/拉/摇/移/zoom/static + 强度） ④ librosa BPM 分析（>110 fast_cut / 80-110 medium / <80 slow_cinematic） ⑤ OSS 上传关键帧 + 豆包 VLM 色调/构图/光线分析 ⑥ 豆包 LLM 整合 style_guide JSON（失败走规则合成降级） 新增渲染参数映射： - 运镜 → ken_burns 参数（push_in→zoom_in_slow、tilt_up→pan+zoom 等 11 种） - 转场 → TransitionEngine xfade 名称（hard_cut→cut/dissolve/wipeleft 等） - 色调 → FFmpeg eq + colorchannelmixer 预设（5 套：warm_vintage/cool_fresh/high_contrast/soft_pastel/dramatic_cinematic） - BPM → BGM 选曲 BPM±5 提示 - build_render_params_for_clip() 按镜头索引聚合可直接喂 URS 的参数 降级链： - FFmpeg 抽帧失败 → VLM 路径；OpenCV 不可用 → static/low；librosa 不可用 → VLM 估计； - LLM/VLM 不可用 → 规则合成 style_guide；任意子步骤异常不抛，best-effort 返回最小可用 style_guide。 资源约束：参考视频 ≤60s/≤100MB，总超时 60s，临时帧 try/finally 清理。 依赖新增：scenedetect==0.6.4、librosa==0.10.2.post1、soundfile==0.12.1（requirements-worker.txt）。 orchestrator 改为从 apps.worker.viral_video.video_analyzer 导入 analyze_video_style， 传入 style_strength 透传 light/medium/strict 三档。 单测 48 条覆盖：映射函数/光流运镜判定/BPM 档位/规则合成/聚合输出/降级/临时文件清理。	2026-09-29 20:41:24 +08:00

Coze Agent	a04e363d1b	chore(worker): improve BGM preset download diagnostics + add upload helper script ... - _prepare_bgm preset branch now differentiates: preset not found / preset exists but audio_url empty (未部署) / download failure, with a clear hint to ops to upload audio and fill preset_bgm.py - final warning now surfaces enabled/audio_url/asset_id/preset_id state so triage is immediate - add scripts/upload_preset_bgm.py: one-shot uploader that uploads mp3s from ./bgm_assets/{preset_id}.mp3 to OSS preset/bgm/, sets public-read ACL, and rewrites packages/domain/preset_bgm.py with the public URL. Dry-run supported. - add bgm_assets/README.md with the 10-preset file naming table	2026-09-29 15:28:36 +08:00
Coze Agent	11c554e43a	fix(gpu-direct): passthrough template title/subtitle/BGM config ... Problem: GPU direct render MVP hardcoded title/subtitle/BGM styles and ignored template config fields: - P0 static subtitle text (subtitle.text) was never rendered - P0 title styles (font/size/color/position/stroke/shadow/bold) all hardcoded - P1 BGM volume hardcoded at 0.35, no fade/offset/adjust-db - P1 ASR subtitle styles (color/size/position/font) ignored - P2 extra_audio_tracks (TTS/voiceover) volume hardcoded at 1.0 Changes: 1. build_direct_render() now accepts title_config/subtitle_config/ bgm_config dicts + static_subtitle_text. 2. Added helpers _hex_to_drawtext_color (#RGB/#RRGGBB/#RRGGBBAA/named), _position_to_drawtext_xy (top/center/bottom), _build_drawtext_filters (shadow layer + main layer, stroke via borderw/bordercolor, bold simulated via same-color borderw). 3. Title parses font/size/color/position/stroke/shadow/bold with safe defaults; legacy title_text still used as fallback. 4. Static subtitle_text renders as full-span (0→total_duration) segment; when ASR segments are present they take priority. 5. BGM reads volume (default 0.3), volume_adjust_db (linear gain), fade_in/fade_out (afade), audio_offset (adelay ms|ms), and honors enabled=false even if path supplied. Volume clamped to [0,1.5]. 6. _try_gpu_direct() now passes cfg['title']/['subtitle']/['bgm'] whole dicts through, computes static_subtitle_text for non-auto subs, and sources extra_audio_tracks volume from audio_tracks_config (voiceover tracks) instead of hardcoding 1.0. 7. DirectRenderPlan exposes filter_complex for testing. 8. Added 24 unit tests covering: default backward-compat, color hex/BGR conversion (short/long/alpha/invalid), position (top/center/bottom), stroke, shadow (two drawtext layers), font override, enabled flag, static subtitle full-span, ASR style passthrough, BGM volume/fade/offset/adjust-db/enabled=false, extra audio volume, bold simulation, ASR vs static priority, volume clamping. Fixes template-style rendering not taking effect in GPU pipeline.	2026-09-29 14:44:11 +08:00
