It has 7,114 GitHub stars and is released under the GPL-3.0 license.

基于 LizardByte/Sunshine 的增强分支，专注于 Windows 主机的游戏串流体验 因此在编码层加入了 HLG（Hybrid Log-Gamma, ITU-R BT.2100）支持，采用相对亮度映射： - 场景参考式亮度适配：HLG 基于相对亮度曲线，显示端根据自身峰值亮度自动进行色调映射，低亮度设备上暗部细节保留显著优于 PQ - 高光区域平滑滚降：HLG 的对数-伽马混合传输函数在高亮区域提供渐进式滚降，避免 PQ 硬截断导致的高光色阶断裂 - 天然 SDR 向后兼容：HLG 信号可直接被 SDR 显示器解码为标准 BT.709 画面，无需额外的色调映射处理
