So make sure you set `export GO111MODULE=on`, and explicitly specify `/v2` or `/v3` when importing. 25 26 27 **[example applications](examples/README.md)** contains code samples of common things people build with Pion WebRTC. 28 29 **[example-webrtc-applications](https://github.com/pion/example-webrtc-applications)** contains more full featured examples that use 3rd party libraries. 30 31 **[awesome-pion](https://github.com/pion/awesome-pion)** contains projects that have used Pion, and serve as real world examples of usage. 32 33 **[GoDoc](https://pkg.go.dev/github.com/pion/webrtc/v3)** is an auto generated API reference. All our Public APIs are commented. 34 35 **[FAQ](https://github.com/pion/webrtc/wiki/FAQ)** has answers to common questions. If you have a question not covered please ask in [Slack](https://pion.ly/slack) we are always looking to expand it. 36 37 Now go build something awesome! Here are some **ideas** to get your creative juices flowing: 38 * Send a video file to multiple browser in real time for perfectly synchronized movie watching. 39 * Send a webcam on an embedded device to your browser with no additional server required! 40 * Securely send data between two servers, without using pub/sub. 41 * Record your webcam and do special effects server side. 42 * Build a conferencing application that processes audio/video and make decisions off of it. 43 * Remotely control a robots and stream its cameras in realtime. 44 45 ### Want to learn more about WebRTC? 46 Join our [Office Hours](https://github.com/pion/webrtc/wiki/OfficeHours). Come hang out, ask questions, get help debugging and 47 hear about the cool things being built with WebRTC. We also start every meeting with basic project planning. 48 49 Check out [WebRTC for the Curious](https://webrtcforthecurious.com). A book about WebRTC in depth, not just about the APIs. 50 Learn the full details of ICE, SCTP, DTLS, SRTP, and how they work together to make up the WebRTC stack. 51 52 This is also a great resource if you are trying to debug. Learn the tools of the trade and how to approach WebRTC issues. 53 54 This book is vendor agnostic and will not have any Pion specific information. 55 56 ### Features 57 #### PeerConnection API 58 * Go implementation of [webrtc-pc](https://w3c.github.io/webrtc-pc/) and [webrtc-stats](https://www.w3.org/TR/webrtc-stats/) 59 * DataChannels 60 * Send/Receive audio and video 61 * Renegotiation 62 * Plan-B and Unified Plan 63 * [SettingEngine](https://pkg.go.dev/github.com/pion/webrtc/v3#SettingEngine) for Pion specific extensions 64 65 66 #### Connectivity 67 * Full ICE Agent 68 * ICE Restart 69 * Trickle ICE 70 * STUN 71 * TURN (UDP, TCP, DTLS and TLS) 72 * mDNS candidates 73 74 #### DataChannels 75 * Ordered/Unordered 76 * Lossy/Lossless 77 78 #### Media 79 * API with direct RTP/RTCP access 80 * Opus, PCM, H264, VP8 and VP9 packetizer 81 * API also allows developer to pass their own packetizer 82 * IVF, Ogg, H264 and Matroska provided for easy sending and saving 83 * [getUserMedia](https://github.com/pion/mediadevices) implementation (Requires Cgo) 84 * Easy integration with x264, libvpx, GStreamer and ffmpeg. 85 * [Simulcast](https://github.com/pion/webrtc/tree/master/examples/simulcast) 86 * [SVC](https://github.com/pion/rtp/blob/master/codecs/vp9_packet.go#L138) 87 * [NACK](https://github.com/pion/interceptor/pull/4) 88 * [Sender/Receiver Reports](https://github.com/pion/interceptor/tree/master/pkg/report) 89 * [Transport Wide Congestion Control Feedback](https://github.com/pion/interceptor/tree/master/pkg/twcc) 90 * [Bandwidth Estimation](https://github.com/pion/webrtc/tree/master/examples/bandwidth-estimation-from-disk) 91 92 #### Security 93 * TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 and TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA for DTLS v1.2 94 * SRTP_AEAD_AES_256_GCM and SRTP_AES128_CM_HMAC_SHA1_80 for SRTP 95 * Hardware acceleration available for GCM suites 96 97 #### Pure Go 98 * No Cgo usage 99 * Wide platform support 100 * Windows, macOS, Linux, FreeBSD 101 * iOS, Android 102 * [WASM](https://github.com/pion/webrtc/wiki/WebAssembly-Development-and-Testing) see [examples](examples/README.md#webassembly) 103 * 386, amd64, arm, mips, ppc64 104 * Easy to build *Numbers generated on Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz* 105 * **Time to build examples/play-from-disk** - 0.66s user 0.20s system 306% cpu 0.279 total 106 * **Time to run entire test suite** - 25.60s user 9.40s system 45% cpu 1:16.69 total 107 * Tools to measure performance [provided](https://github.com/pion/rtsp-bench) 108 109 ### Roadmap 110 The library is in active development, please refer to the [roadmap](https://github.com/pion/webrtc/issues/9) to track our major milestones. 111 We also maintain a list of [Big Ideas](https://github.com/pion/webrtc/wiki/Big-Ideas) these are things we want to build but don't have a clear plan or the resources yet. 112 If you are looking to get involved this is a great place to get started! We would also love to hear your ideas! Even if you can't implement it yourself, it could inspire others. 113 114 ### Sponsoring 115 Work on Pion's congestion control and bandwidth estimation was funded through the [User-Operated Internet](https://nlnet.nl/useroperated/) fund, a fund established by [NLnet](https://nlnet.nl/) made possible by financial support from the [PKT Community](https://pkt.cash/)/[The Network Steward](https://pkt.cash/network-steward) and stichting [Technology Commons Trust](https://technologycommons.org/). 116 117 ### Community 118 Pion has an active community on the [Slack](https://pion.ly/slack). 119 120 Follow the [Pion Twitter](https://twitter.com/_pion) for project updates and important WebRTC news. 121 122 We are always looking to support **your projects**. Please reach out if you have something to build! 123 If you need commercial support or don't want to use public methods you can contact us at [team@pion.ly](mailto:team@pion.ly) 124 125 ### Contributing 126 Check out the [contributing wiki](https://github.com/pion/webrtc/wiki/Contributing) to join the group of amazing people making this project possible: [AUTHORS.txt](./AUTHORS.txt) 127 128 ### License 129 MIT License - see [LICENSE](LICENSE) for full text
