Bug1（原素材音轨丢失）：concat 改为 v=1:a=1，为每段[i:a]加 atrim/asetpts/atempo/aresample 预处理，concat 输出[acat]主音轨，再与TTS/BGM一起amix。 Bug2（音画不同步）：amix duration 改为 longest（原first在纯BGM时跟随BGM全长）， mix末尾加 atrim=0:total_duration + asetpts=PTS-STARTPTS 精确截断到视频时长， 命令行再加 -shortest 兜底。 P1 边缘裁剪入GPU：将原固定3%中心裁剪改为四边独立随机2~5%（与 ffmpeg_utils.random_edge_crop 口径一致），在GPU filter_complex内一步完成；新增 RenderResult.edge_crop_applied 标志 经 RenderAdapter → generate_video 传递，外层CPU random_edge_crop 在GPU已做时跳过， 省掉约5s CPU libx264二次重编码。 |
