# 1080p - 极致优化版本（Ubuntu Server 专用，高质量 + YouTube直播推荐友好 + 强防Content ID）
# 针对Ubuntu server（通常CPU较强，无iOS硬件限制）：
# - preset 升级到 medium 或 slow（如果CPU能承受，质量显著提升）
# - 比特率保持8500k-10000k峰值，符合YouTube 1080p直播高质量推荐
# - 音频防Content ID：音高+5%、频率偏移、多段EQ衰减背景音乐、强压缩、相位扰动（使用aphaser正确参数）、轻噪门
# - 移除无效参数，修复之前aphaser错误（aphaser支持in_gain/out_gain/delay/decay/speed/type，不支持feedback）
# - Ubuntu下推荐使用最新FFmpeg（apt install ffmpeg 或从源码编译支持libx264）
