在 2020 年 Twitch 和 ACM 合作举办了低延迟下的 ABR 算法大挑战 [Adaptation Algorithms for Near-Second Latency](https://2020.acmmmsys.org/lll_challenge.php)。比赛的第一名是 Unified Streaming 的 [L2A-LL(Learn2Adapt-LowLatency) 算法](https://dl.acm.org/doi/abs/10.1145/3339825.3397042) ,第二名是新加坡国立大学的 [LoL(Low-on-Latency)算法](https://dl.acm.org/doi/10.1145/3339825.3397043)。由于 Twitch 播放...
在 2020 年 Twitch 和 ACM 合作举办了低延迟下的 ABR 算法大挑战 Adaptation Algorithms for Near-Second Latency。比赛的第一名是 Unified Streaming 的 L2A-LL(Learn2Adapt-LowLatency) 算法 ,第二名是新加坡国立大学的 LoL(Low-on-Latency)算法。由于 Twitch 播放器不是开源的,比赛是基于 dash.js 播放器,目前 dash.js 也集成了这两种 ABR 算法。## 总结LLDASH 和 LHLS 非常相似,都是使用 HTTP/1.1 的 Chunked transfer e...
