The Audio_device is a WEBRTC audio device module. Encapsulates audio device-related code for each platform Audio device encapsulates two sets of sound code in Android. 1. Use JNI to invoke Java's media. 2. Operate directly through the native C interface of the OpenSL es. The native interface is naturally more efficient, but the downside is that OpenSL requires Android 2.3+. OpenSL ES (Open sound Library for Embedded systems) is a hardware audio accel

This article mainly introduces the multi-person video conferencing Service end architecture, the article from the blog Park Rtc.blacker, reproduced please explain the source.With the rapid development of mobile Internet, many companies want to intervene in online education, smart home, multi-person video, security monitoring and other fields, although they are video communications, but their service-side architecture and point-to-point communication big do not want the same,In most cases, single

When using WEBRTC on the Android layer, the UI changes are triggered by the native layer callback, such as when to draw the other's video window, when to indicate that both connections have been established, etc...I'm going to list what I know now for the memo.Onaddstream (), which indicates that the associated media stream has been initialized successfully (but does not establish a connection), usually at this time display the other side of the video

The purpose of this article is to save you 10 hours (or more) of your life, or to waste 10 minutes. WEBRTC's compilation has been called a nightmare as a large cross-platform base library that Google has frequently updated. If you happen to want to compile WEBRTC under Windows, then you'd better evaluate your patience and IQ in advance. As of now, I have tried almost all the articles in the Chinese blog community, which can be said to have failed. I d

There are Licode and kurento in contact.Licode Flaw: Limited documentation support, Licode app client library only JSKurento Advantages: Complete Documentation, demo-ready, Packaging API is more complete. Its main features are: Networked streaming protocols, including HTTP, RTP and WebRTC.

Today let me find a gstreamer of a bull fork of the killer, the mind immediately thought of a general framework and plan, with Gst-inspector first object introspection property detection, and then sacrificed Gst-launcher Broadsword for pipeline test, and finally use C to achieve the pipeline logic source code , you can implement WEBRTC-based video surveillance and live streaming services. Real-time two-person video call or multi-person meeting, after

The WEBRTC audio and video parsing process consists of multiple threads:1. RTP Network stream receive thread (RTP stream reciever thread)2. Audio and video decode thread (decode thread)3. Render threads (render thread)RTP network stream receive thread (RTP stream reciever thread):Receive network RTP packets, parse RTP packets, get audio and video packets. The resolved RTP packet is added to the Rtpstreamreceiver::frame_buffer_ or eventually joined Vcm

The bandwidth adaptive algorithm in WEBRTC is divided into two types: 1, the originator bandwidth control, the principle is the RTCP in the packet loss statistics to dynamically increase or decrease the bandwidth, in the reduction of bandwidth using the TFRC algorithm to increase the smoothness. 2, the receiver bandwidth estimation, the principle is and by the receipt of RTP data, the estimated bandwidth, with the Kalman filter, the transmission time

The AEC algorithm in WEBRTC belongs to the piecewise fast frequency domain Adaptive filtering algorithm, partioned block Frequeney Domain Adaptive filter (PBFDAF).To determine whether the distal and proximal end of the conversation, also known as double-ended detection, the following four conditions need to be monitored:1. Only the far end to speak, at this time the

WEBRTC use of audio and video engines At the request of the group of brothers, now how to use WEBRTC audio and video demo put out. Code format is very bad, you look at the spectators do not bother to tidy up. #include

This article provides an overview of the WEBRTC audio processing flow, as shown in the following diagram: WebRTC an audio session is abstracted into a channel, such as A and b for audio calls, a needs to establish a channel and b for audio data transmission. The figure above has three channel, each channel contains codec and real-time Transport protocol (real-time Transport Protocol,RTP)/ The real-time Tra

in e-commerce, remote training, video conferencing, customer support and so on. Mentioned streaming media, we are more familiar with the network based on fixed-bandwidth streaming media, but for wireless streaming media is rarely heard, however, wireless streaming media is not to be overlooked. As an important application of wireless streaming media is video messages and video messages, through video messages and emails, we are the realization of wireless streaming media live and
