"""让屏幕采集器在设置变化时重建。
|
|
|
|
原来的实现：
|
|
def _ensure_capturer(self):
|
|
if self._capturer is None:
|
|
self._capturer = ScreenCapturer(
|
|
max_width=..., quality=...)
|
|
return self._capturer
|
|
|
|
问题：**缓存住了**。改了 screen_max_width / screen_quality 之后，
|
|
正在推流的话新设置永远不生效 —— 用户会以为"改了没用"。
|
|
|
|
修法：记住建它时用的参数，参数变了就重建。
|
|
|
|
顺带把 relay_saver 里那句 reset_capturer() 去掉（Actions 上没这个方法，
|
|
写了也是白写）。
