干掉大小流切换 I 帧！阿里云 RTC QoS 及视频编码联合优化之切流编码

如果要在两条分辨率不同的视频流之间切换，尽管这两条流的画面内容基本一样，但是由于两条流的参考帧不同，分辨率不同，目前所有的视频编码标准都无法做到利用帧间预测编码得到编解码匹配的结果，而帧内预测编码即I帧的压缩效率是非常低下的，因此在切流处很容易造成视频质量下降或由于码率突增引起的卡顿；阿里云RTC ...

阿里云iot控制台上给未检测到离线的设备发送QoS=1的消息

阿里云iot，在控制台页面上给设备订阅的自定义topic发送QoS=1的消息，该消息发送时设备处于刚断电但阿里云未检测到离线状态，设备上电重新连接到阿里云iot后并不能收到该消息，请问是什么原因?

阿里云 RTC QoS 弱网对抗之 LTR 及其硬件解码支持

作者｜安基程、陶森柏、田伟峰审校｜泰一Long Term Reference (LTR) 抗弱网原理参考帧丢失的 I 帧恢复在 RTC 场景下一般的编码参考策略是向前一帧参考（在不考虑 temporal svc 的情况下），因为一般情况下参考距离越近，相似性越好，则压缩效果越好，出于实...

阿里云 RTC QoS 弱网对抗之变分辨率编码

作者｜安基程、田伟峰审校｜泰一视频编码中的变分辨率问题及解决变分辨率在弱网场景的实际应用中非常常见，网络状况不好的时候降低分辨率可以降低码率，减少块效应，网络好的时候增加分辨率可以提升清晰度及主观体验。目前主流的视频编码标准，比如 H.264、H.265，在编码过程中如果要进行分辨率切换ÿ...
