在 Mac 上测试了下,好像不能修改帧率,不知道作者是否遇到这个问题?
在iOS 端调用 displayPixelBuffer:方法渲染摄像头回调的CVPixelBufferRef 数据时 可能会出现无规律的崩溃 报错信息包括
MTLCommandBuffer didCompleteWithStartTime:endTime:error
IOGPUMetalCommandBuffer didCompleteWithStartTime:endTime:error
MTLCommandBuffer presentDrawable:options:
MTLCommandBuffer didScheduleWithStartTime:endTime:error:
IOGPUNotificationQueueDispatchAvailableCompletionNotifications
实在是不太理解 可能是涉及了在渲染的runloop内持有了空指针
不知道作者能不能有时间回复一下 谢谢
