Member Function Documentation

◆ AllocateAndStart() [1/2]

virtual void AVE::VideoCaptureDevice::AllocateAndStart ( Client * client )

pure virtual

◆ AllocateAndStart() [2/2]

virtual void AVE::VideoCaptureDevice::AllocateAndStart ( VideoCaptureDeviceBase::Client * client )

inlineoverridevirtual

初始化采集使用的资源，例如启动线程，保存SDK传递的回调

Parameters

client SDK实现回调的对象，一定要保存

Note: SDK 第一次调用StartPublish或PlayStream时调用，; 接口调用顺序:1、VideoCaptureFactory::Create 2、VideoCaptureDevice::AllocateAndStart; 一定要实现

Implements AVE::VideoCaptureDeviceBase.

◆ GetInterface()

virtual void * AVE::VideoCaptureDevice::GetInterface ( )

inlineoverridevirtual

检查是否支持SupportsVideoCapture接口

Note: SDK会在VideoCaptureFactory::Create后调用此方法，如果返回不会空，SDK会按照SupportsVideoCapture; 透传SDK的调用; 一定要实现

Implements AVE::VideoCaptureDeviceBase.

◆ SupportBufferType()

virtual VideoPixelBufferType AVE::VideoCaptureDevice::SupportBufferType ( )

inlineoverridevirtual

获取采集callback的类型

Note: SDK会在AllocateAndStart前先调用此接口实例化对应的client，再调用AllocateAndStart; 一定要实现

Implements AVE::VideoCaptureDeviceBase.
