1. VideoEngineImpl
VideoEngine对外提供的集成接口实现类, 其继承了VideoEngine对外提供的所有接口实现类,包括ViEBaseImpl/ViECaptureImpl/ViEFileImpl/ViEImageProcessImpl/ViENetworkImpl/ViERTP_RTCPImpl/ViEExternalCodecImpl/VideoEngine
VideoEngine对外提供的操作类,基本都有此类提供,如创建删除通道、开始停止发送、开始停止接受等
负责channel处理流程控制,如开始发送、接受等;音频通道的链接
类似ViEChannel,在某些应用场景下可以替换VieChannel;但只负责发送Channel
VideoEngine的Render流程控制类,控制Render的流程,如启动、暂停,处理回调数据,管理具体的Render操作类; 注册进VieChannel
VoEAudioProcessingImpl/VoECodecImpl/VoEDtmfImpl/VoEExternalMediaImpl/VoEFileImpl/VoEHardwareImpl/VoENetEqStatsImpl/VoENetworkImpl/VoERTP_RTCPImpl/VoEVideoSyncImpl/VoEVolumeControlImpl/VoEBaseImpl
其继承AudioTransport类,还需处理抓取的音频(送至channel中),和需要放音的音频(从channel中取)
