     1  # broadcast
     2  broadcast is a Pion WebRTC application that demonstrates how to broadcast a video to many peers, while only requiring the broadcaster to upload once.
     3  
     4  This could serve as the building block to building conferencing software, and other applications where publishers are bandwidth constrained.

     6  ## Instructions
     7  ### Download broadcast
     8  ```
     9  export GO111MODULE=on
    10  go get github.com/pion/webrtc/v3/examples/broadcast
    11  ```
    12  
    13  ### Open broadcast example page
    14  [jsfiddle.net](https://jsfiddle.net/us4h58jx/) You should see two buttons `Publish a Broadcast` and `Join a Broadcast`
    15  
    16  ### Run Broadcast
    17  #### Linux/macOS
    18  Run `broadcast` OR run `main.go` in `github.com/pion/webrtc/examples/broadcast`
    19  
    20  ### Start a publisher
    21  
    22  * Click `Publish a Broadcast`
    23  * Press `Copy browser SDP to clipboard` or copy the `Browser base64 Session Description` string manually
    24  * Run `curl localhost:8080/sdp -d "$BROWSER_OFFER"`. `$BROWSER_OFFER` is the value you copied in the last step.
    25  * The `broadcast` terminal application will respond with an answer, paste this into the second input field in your browser.
    26  * Press `Start Session`
    27  * The connection state will be printed in the terminal and under `logs` in the browser.
    28  
    29  ### Join the broadcast
    30  * Click `Join a Broadcast`
    31  * Copy the string in the first input labelled `Browser base64 Session Description`
    32  * Run `curl localhost:8080/sdp -d "$BROWSER_OFFER"`. `$BROWSER_OFFER` is the value you copied in the last step.
    33  * The `broadcast` terminal application will respond with an answer, paste this into the second input field in your browser.
    34  * Press `Start Session`
    35  * The connection state will be printed in the terminal and under `logs` in the browser.
    36  
    37  You can change the listening port using `-port 8011`
    38  
    39  You can `Join the broadcast` as many times as you want. The `broadcast` Golang application is relaying all traffic, so your browser only has to upload once.
