save-to-disk

save-to-disk

save-to-disk is a simple application that shows how to record your webcam/microphone using Pion WebRTC and save VP8/Opus to disk.

If you wish to save VP8/Opus inside the same file see save-to-webm

If you wish to save AV1 instead see save-to-disk-av1

You can then send this video back to your browser using play-from-disk

Instructions

Download save-to-disk

go install github.com/pion/webrtc/v4/examples/save-to-disk@latest

Open save-to-disk example page

jsfiddle.net you should see your Webcam, two text-areas and two buttons: Copy browser SDP to clipboard, Start Session.

Run save-to-disk, with your browsers SessionDescription as stdin

In the jsfiddle the top textarea is your browser's Session Description. Press Copy browser SDP to clipboard or copy the base64 string manually. We will use this value in the next step.

Linux/macOS

Run echo $BROWSER_SDP | save-to-disk

Windows

1. Paste the SessionDescription into a file.
2. Run save-to-disk < my_file

Input save-to-disk's SessionDescription into your browser

Copy the text that save-to-disk just emitted and copy into second text area

Hit 'Start Session' in jsfiddle, wait, close jsfiddle, enjoy your video!

In the folder you ran save-to-disk you should now have a file output-1.ivf play with your video player of choice!

Note: In order to correctly create the files, the remote client (JSFiddle) should be closed. The Go example will automatically close itself.

Congrats, you have used Pion WebRTC! Now start building something cool
