"""加「跨网络省流量」开关。
|
||
|
||
问题（实测出来的）：
|
||
经隧道传一个 256KB 的屏幕分块，上行要 9.4 秒。
|
||
因为经中转的那条线上，一帧画面的 JSON（含 base64）约 350KB，
|
||
而这条 4G 线路的上行只有 ~37 KB/s。
|
||
→ 屏幕镜像会卡成幻灯片。
|
||
|
||
做法：
|
||
开这个开关就把屏幕流降一档：
|
||
分辨率 480 -> 360
|
||
画质 55 -> 40
|
||
一帧从 ~350KB 降到 ~60KB，速度差 5 倍以上。
|
||
局域网直连时不用开（本来就不慢）。
|
||
|
||
关掉时**还原成原来的值** —— 所以先把原值存下来。
