问题

unified渲染引擎多片段concat时exit=234失败，原因是视频分辨率/音频采样率/声道等参数不统一。

修复

视频（2项）

  • main/broll层：scale+crop → scale+pad（force_original_aspect_ratio=decrease + 黑边填充）
  • background层：保持increase+crop（背景铺满不变）
  • fps滤镜已存在，确保所有clip帧率统一

音频（2项）

  • concat主音频：每个clip前加aformat=48000Hz+stereo+fltp
  • 独立音轨mix：每条轨道前加aformat归一化
  • 单clip直通：输出参数加-ar 48000 -ac 2

测试

  • 新增20+单元测试，覆盖4项normalize完整验证
  • 105个测试全部通过
  • 更新旧的crop测试断言为pad模式

视频：
- main/broll层从increase+crop改为decrease+pad（留黑边不裁剪）
- background层保持increase+crop（背景铺满）

音频：
- concat主音频前每个clip加aformat归一化(48000Hz/stereo/fltp)
- 独立音轨amix前加aformat归一化
- 单clip直通模式输出也加采样率/声道归一化

测试：
- 新增20+单元测试覆盖4项normalize
- 更新旧的crop测试为pad模式
- _make_service支持output_fps/output_width/output_height参数
