大概率是我的音视频同步没做好，你试试把音频禁用掉看看

这个问题在你还没加上音频就已经存在了，所以我猜应该跟音频没有关系

有没有地址我这边可以访问到的？

High latency of streaming is caused by default videoChunk value maybe. If you change tab in browser - latency is higher. FlvPlayer keeps frames in memory and will show it when you back to tab in speed close to framerate. When i set videoChunk to 5*1024, player is showing all saved frames like a accelerated video and back to ~1s latency. Is it possible to add an option for start render from newest frame rather than old frames?

P.S. It seems to me that when i change tab, browser's memory filling up by old frames and despite tab refresh data is still saved - close and create new tab helps.
