     1  # save-to-disk
     2  save-to-disk is a simple application that shows how to record your webcam/microphone using Pion WebRTC and save VP8/Opus to disk.
     3  
     4  If you wish to save VP8/Opus inside the same file see [save-to-webm](https://github.com/pion/example-webrtc-applications/tree/master/save-to-webm)
     5  
     6  If you wish to save AV1 instead see [save-to-disk-av1](https://github.com/pion/webrtc/tree/master/examples/save-to-disk-av1)
     7  
     8  You can then send this video back to your browser using [play-from-disk](https://github.com/pion/example-webrtc-applications/tree/master/play-from-disk)

    10  ## Instructions
    11  ### Download save-to-disk
    12  ```
    13  go install github.com/pion/webrtc/v4/examples/save-to-disk@latest
    14  ```
    15  
    16  ### Open save-to-disk example page
    17  [jsfiddle.net](https://jsfiddle.net/s179hacu/) you should see your Webcam, two text-areas and two buttons: `Copy browser SDP to clipboard`, `Start Session`.
    18  
    19  ### Run save-to-disk, with your browsers SessionDescription as stdin
    20  In the jsfiddle the top textarea is your browser's Session Description. Press `Copy browser SDP to clipboard` or copy the base64 string manually.
    21  We will use this value in the next step.
    22  
    23  #### Linux/macOS
    24  Run `echo $BROWSER_SDP | save-to-disk`
    25  #### Windows
    26  1. Paste the SessionDescription into a file.
    27  1. Run `save-to-disk < my_file`
    28  
    29  ### Input save-to-disk's SessionDescription into your browser
    30  Copy the text that `save-to-disk` just emitted and copy into second text area
    31  
    32  ### Hit 'Start Session' in jsfiddle, wait, close jsfiddle, enjoy your video!
    33  In the folder you ran `save-to-disk` you should now have a file `output-1.ivf` play with your video player of choice!
    34  > Note: In order to correctly create the files, the remote client (JSFiddle) should be closed. The Go example will automatically close itself.
