pipeline failed to screencap，画面颜色错误

[FSPaul2498]

使用Python集成MAA，在一个实例下长时间执行不同pipeline task后，会出现崩溃情况，且使用controller.screencap获得的实时截图色彩错误。

====================

后续执行的task均重复最后四行的报错。

我的集成逻辑设置了每次执行task后进行一次controller截图保存，查阅截图发现崩溃后每次controller截图的整体色彩错误，如下
错误的界面截图

实际上此时的界面截图

保持现场并使用MAA Debugger重连AVD发现截图色彩正常，基本可以排除AVD故障的可能性。

opencv 或者说传统图像处理惯用的颜色是 BGR 而非 RGB，screencap 接口返回的也是

崩溃问题给一下具体的复现路径和 maa.log

[FSPaul2498]

崩溃问题给一下具体的复现路径和 maa.log

我设计了41906个case，我的python集成会加载所有这些case，创建一个maa实例，然后每个case顺序执行两个pipeline，两个pipeline的入口task依次为【Start-快速回到搜索页】和【Input-搜索词-*】，*为case id。最后一个正确执行的task为【Input-搜索词-625】，然后下一轮case的【Start-快速回到搜索页】开始发生崩溃。崩溃前controller.screencap获取保存的截图颜色正常，崩溃后开始颜色错误，个人猜测是controller崩溃，连带导致maa实例错误。
maa.log如下（log较长，我删减了最后一个正确执行的task之前的部分内容和后续重复失败task的部分内容）
maa_clean.log

感觉理解有偏差，你说的崩溃是指 crash / core dump 吗？

[FSPaul2498]

感觉理解有偏差，你说的崩溃是指 crash / core dump 吗？

啊非常抱歉 可能是我表述的问题，我指的是发生异常后，MAA实例无法再成功执行任何task，每次run_task都会卡在首个task打印以上报错然后结束task，但MAA实例仍然存活，并没有 crash / coredump，这也许叫做“异常运行状态”更准确一些

1. 这里获取的实时截图是在所谓崩溃后才错误的吗? 即, 在崩溃前获取的颜色是正常的吗?
2. 如果令每个case独立创建实例, 结束后销毁, 可以复现问题吗?

1. 是的，前面几百个case成功执行后的controller截图色彩都是正常的，在后续case出现异常之后，截图色彩也出现了异常。
2. 因为case数量较多，每个case独立创建MAA实例的方式会极大增加测试时间成本，因此尚未测试。我在手动终止以上异常MAA实例后，重新执行我的Python集成创建实例，可以正确开始新一轮测试，猜测理论上此方法应该不会复现问题。

[neko-para]

其实实例创建的成本不算高, 倒是controller创建确实不低; 可以先考虑每100-200个case之后移除并重新创建一次controller, 应该能暂时绕过现在的问题

[neko-para]

看日志执行了600多个case之后, adb进程拉起来无法绑定管道了, 可以在刚启动和接近500-600case的是用活动监视器看一下是不是fd泄露了
