xiaoxia	b81e91e79a	fix: move -ss back after -i for sample-accurate audio trimming ... Input seek (-ss before -i) uses keyframe seeking which may skip to the wrong keyframe for audio, causing A/V desync in concatenated output. For a rendering service, precision > speed. Use output seeking.	2026-08-24 00:42:46 +08:00
xiaoxia	115455bacc	fix: volume=0 clips retained with silence filter to preserve A/V sync ... - render_audio.py: stop filtering out volume=0 clips from concat; they produce silence via volume=0 filter, keeping timeline aligned - unified_render_service.py: probe audio regardless of volume; volume=0 applied as filter, not by dropping stream - test: update test_silent_clip to verify volume=0 clip retained with volume=0 filter	2026-08-24 00:36:17 +08:00

xiaoxia	41d503299a	fix: -ss as input option before -i, probe exception re-raises ... - render_audio.py: move -ss before -i so FFmpeg uses seek (fast) instead of decode-and-discard (slow) - unified_render_service.py: probe_has_audio fatal exception now logs error and re-raises (fail-fast, no silent audio loss) - test: update probe exception test to expect RuntimeError	2026-08-24 00:21:32 +08:00
xiaoxia	a628b4ca8e	fix: audio filter order (denoise before volume) + clarify reverse path comment ... - _render_pass_through: move volume filter after denoise to avoid amplifying noise before denoising - concat_main_audio: add comment explaining speed/reverse go through filter_complex else branch, not simple path	2026-08-24 00:15:24 +08:00
xiaoxia	2f76509a5b	fix: address AI code review - probe defaults to no audio, safe af filter ... - render_audio.py: simple mode builds af_parts list then joins into single -af (defensive against future multi-clip) - unified_render_service.py: probe_has_audio exception now defaults to False with warning log (was unsafe True) - test: add test_pass_through_probe_exception_defaults_to_no_audio	2026-08-24 00:10:07 +08:00

saas-backend-agent	c2a510331e	fix(worker): render_plan 保留视频原声并尊重每clip音量 ... 根因：render_audio.mix_audio 中 main_clips = [] 无条件丢弃主图层源视频 原声（PR #1249 "避免录入杂音"），导致走新路径 render_plan 生成的成片 没有原声，与预览不一致（用户反馈"音频没有"）。 修复： - mix_audio 保留 main/broll 原声，按 clip.config.volume 控制音量， 无音频流/静音(volume=0)的 clip 安全过滤 - concat_main_audio 单clip与多clip路径均应用 per-clip volume 滤镜 - 直通渲染(_render_pass_through)改为先 probe_has_audio 再决定是否编码 音频，并应用 per-clip volume；不再无条件假设 main 带音频 - stream copy 在音量非默认时回退重编码 - 新增 _clip_volume 辅助函数(render_audio + UnifiedRenderService) - 更新 test_unified_render_service 旧"丢弃原声"断言为新行为 - 新增 test_original_audio_retained.py 9 个回归测试 验证：161 个相关单测全部通过	2026-08-23 23:54:44 +08:00
xiaoxia	d826ae216a	fix: 渲染管线 bool 类型配置防护 — 全面修复 'bool' object has no attribute 'get' 崩溃 ... 根因: plan.config 中某 key 的值可能为 bool 而非 dict， 当 .get() 或 from_dict() 被调用时崩溃。 'or {}' 只能防 None/空值，防不了 True/False。 修复策略（双层防护）: 1. 治本: 所有 from_dict 方法入口加 isinstance(data, dict) 检查 - chroma_key_config.py / color_grade_config.py / noise_reduction_config.py - watermark_config.py / pip_config.py / intro_outro_config.py - reverse_engine.py 2. 治标: 调用方直接 .get() 处加 isinstance 防护 - unified_render_service.py: tts/bgm/title/subtitle/export/bgm - render_adapter.py: bgm/export/title - render_audio.py: bgm/audio_tracks - generation.py: title/subtitle/bgm/export - edit_plan_generation.py: title 共修复 12 个文件，覆盖渲染管线全部 unprotected 调用点	2026-08-16 14:58:30 +08:00
