Order Adjustment of CodecWhen a Web page uses WebRTC to send an SDP, the default codec order is:
VP8
VP9
H264
In C + + code, the first one to match is selected by default (from PeerConnection::CreateAnswer/SetRemoteDescription two methods, you can see). So, we're going to modify the C + + code to change this selection logic.WebRtcVideoChannel2 (webrtcvideoengine2.cc) used by codec, from The Internalencoderfactory Class (internalencoderfactory.cc), either as the sende

Apple unveiled a new ICloud storage space upgrade and cloud computing services at this year's WWDC conference to strengthen ICloud's competitiveness. Replacing the VAIO notebook with a MacBook, or replacing the iPhone with Moto X, is simple, but the data transfer is difficult, which also increases the level of platform loyalty. In recent years, Apple's competitors have introduced a variety of better control of user data, so the ICloud storage space added more features, significantly lower prices
