MetaRTC implements the webrtc protocol, supports webrtc/srt/rtmp, and has two versions of pure C and C++. The webrtc support is original, without citing the Google webrtc code, and can interoperate with the Google Webrtc library and browser. Support windows/linux/android etc. Remark: metaRTC2.0/metaRTC3.0/metaRTC4.0 stops updating Remark:metaRTC6.0 is stable ## metaRTC6.0 stable version download https://github.com/metartc/metaRTC/releases/tag/v6.0-b2 ## The difference between MetaRTC and Google Webrtc advantage: ### MetaRTC compilation is simple It is difficult to compile webrtc, and there are dozens of G in the warehouse. The metaRTC code is small and easy to compile. And metartc has a complete compilation tutorial and video at station B. ### webrtc is developed using c++ and is bulky and not suitable for embedding. metartc is mostly developed in the c language and is inherently suitable for embedding. easy to re-develop ### the amount of meta code is small Webrtc is developed using c++, which is bulky and not suitable for embedded. Metatc is mostly developed in C language, which is naturally suitable for embedded. ### Easy secondary development webrtc is developed by Google, the amount of code is large, and the secondary development is difficult. The amount of meta code is small, the difficulty of secondary development is small, and there is a complete Chinese community. ### create a chinese ecology metaRTC is seamlessly compatible with SRS and ZLM, and the code integrates its signaling interactions. metaRTC has implemented national secret gmssl support. metaRTC has submitted a Loongson ecological construction application and will increase support for domestic chips and operating systems. ### Better for Embedded/IoT Weak embedded computing power, not suitable for webrtc Embedded developers are mostly pure C developers ### Provide H265 complete solution H265 can save half of the bandwidth than H264. The H265 ecosystem is relatively mature in China. Many industry chips such as security support H265 encoding. metaRTC supports H265 version of webrtc metaRTC provides SRS with support for H265 ( http://github/metartc/srs-webrtc265 ) ### Built-in pure C version signaling service The metap2p project has built-in signaling services, and signaling processing is implemented in pure C. Support datachannel/websocket/http ### Integrate ffmpeg to support static compilation and integration into ffmpeg Integrating ffmpeg enables ffmpeg to support webrtc push-pull streaming and p2p The new version of metaRTC integrated with FFmpeg supports AEC/AGC/ANC functions such as echo cancellation ## metaRTC function 1.Video encoding 8bit: x264, x265, vaapi, nvenc, etc., the second phase adds AV1 and a variety of hardware encoding. 2.video encoding 10bit: x265, vaapi, nvenc, etc. 3.video decoding: ffmpeg and yangh264decoder. 4.VR: INTERACTIVE AND RECORDING, LIVE BROADCASTING, ETC. OF VIRTUAL VIDEO BASED ON KEYING. 5.8bit and 10bit web players: yangplayer 6.Audio: Opus, Aac, Speex, Mp3 and other audio codecs. 7.AUDIO: AEC, AGC, ANS AND SOUND SYNTHESIS. 8.transport: webrtc, rtmp, srt, webrtc for their own implementation, does not use the google lib library. 9.Live: rtmp, srt, webrtc, HLS, HTTP-FLV. 10.8bit recording: h264, h265 mp4 and flv. 11.10bit recording: mp4 of h265 12.screen sharing and control are implemented. 13. a variety of processing of sound and images is realized. 14. professional camera gimbal control with multi-lens guide switching. 15.supports both 32-bit and 64-bit programming. ## Scope of application Audio and video applications: video conferencing/recording and live broadcasting/live interactive IPC/cloud games/cloud 3D/metaverse RTC Industry application: distance education / telemedicine / remote office command and dispatch / security monitoring / financial video AI / video recording and broadcasting / e-commerce live broadcast ## P2P support Built-in signaling service one-to-many live broadcast browser p2p communication two-way intercom and conference ## ARM support Support ARM-Linux Support ARM-Android Provide ARM compilation scripts Provide third-party ARM compilation documents ## metaRTC WeChat group You can add WeChat taihang82 ## module ### libmetartccore6 webrtc/rtmp protocol implementation and basic application C library, which can be integrated into ffmpeg . If the platform has acquisition and decoding, only libmetartccore5 is needed, libmetartc5 is not required ### libmetartc6 Realize acquisition, encoding, decoding, transmission (SRT implementation), and push-pull streaming ### metapushstream6/metapushstream6_android Push stream and record demo metapushstream3_android for Android ### metaplayer6/metaplayer6_android Pull stream demo, metaplayer5_android is Android version ### metap2p6 p2p demo, supports one-to-one and one-to-many, metaplayer5 can pull streams directly from metap2p6 Unlike metapushstream5 and metaplayer5, metap2p5 supports full duplex, that is, one connection supports both push and pull streams ### yangwincodec nvidia/intel gpu encoding The following is an enthusiastic netizen using metaRTC (yangwebrtc) test situation, end-to-end latency of 40ms. ![](https://img-blog.csdnimg.cn/fbd331e04ad94910804a5786f725a297.png?x-oss-process=image/watermark,type_ZHJvaWRzYW5zZmFsbGJhY2s,shadow_50,text_Q1NETiBAeWFuZ3J0Yw==,size_20,color_FFFFFF,t_70,g_se,x_16) ## compile the tutorial MetaRTC Embedded Webrtc Programming Guide https://blog.csdn.net/m0_56595685/article/details/122010285 Video Compilation Tutorial https://www.bilibili.com/video/BV1d3411r742/ ### P2P audio and video intercom demo between metaRTC4.0 and browser webrtc https://blog.csdn.net/m0_56595685/article/details/124784019 ### metaRTC realizes audio and video intercom and video conference of P2P application of webrtc https://blog.csdn.net/m0_56595685/article/details/124067383 ### P2P audio and video intercom demo between metaRTC4.0 and browser webrtc https://blog.csdn.net/m0_56595685/article/details/124784019 ### P2P communication programming guide between metaRTC and browser webrtc https://blog.csdn.net/m0_56595685/article/details/124015458 ### metaRTC implements Android webrtc live streaming https://blog.csdn.net/m0_56595685/article/details/123657024 ### metaRTC (ARM linux64) compilation guide https://blog.csdn.net/m0_56595685/article/details/123900651 ### MetaRTC Embedded Webrtc Programming Guide metaRTC Embedded Webrtc Programming Guide https://blog.csdn.net/m0_56595685/article/details/122139482 https://blog.csdn.net/m0_56595685/article/details/122010285 ### metaRTC builds video conferencing https://blog.csdn.net/m0_56595685/article/details/122775443 ### Build a low-latency H265 webrtc application that saves half the bit rate https://blog.csdn.net/m0_56595685/article/details/121880362 ### Build a linux and embedded HD recording and broadcasting system that supports H264 and H265 https://blog.csdn.net/m0_56595685/article/details/121735106 ### Build a dual-teacher classroom that supports embedded intelligent terminals across platforms to realize remote interactive teaching https://blog.csdn.net/m0_56595685/article/details/121735106 ### metaRTC integrates FFmpeg to implement audio functions such as echo cancellation (3A) https://blog.csdn.net/m0_56595685/article/details/122682713 ### metaRTC is integrated into ffmpeg to implement srs's webrtc push-pull stream https://blog.csdn.net/m0_56595685/article/details/122642347 ### metaRTC is integrated into ffmpeg to implement webrtc streaming playback of srs https://blog.csdn.net/m0_56595685/article/details/122594797 ### SRS+metaRTC+FFmpeg helps live broadcast enter a new era of webrtc live broadcast interaction https://blog.csdn.net/m0_56595685/article/details/122697381
