insertable-streams

insertable-streams demonstrates how to use insertable streams with Pion. This example modifies the video with a single-byte XOR cipher before sending, and then decrypts in Javascript.

insertable-streams allows the browser to process encoded video. You could implement E2E encryption, add metadata or insert a completely different video feed!

Instructions

Create IVF named output.ivf that contains a VP8 track

ffmpeg -i $INPUT_FILE -g 30 output.ivf

Download insertable-streams

go install github.com/sepehrEslami81/webrtc/v3/examples/insertable-streams@latest

Open insertable-streams example page

jsfiddle.net you should see two text-areas and a 'Start Session' button. You will also have a 'Decrypt' checkbox. When unchecked the browser will not decrypt the incoming video stream, so it will stop playing or display certificates.

Run insertable-streams with your browsers SessionDescription as stdin

The output.ivf you created should be in the same directory as insertable-streams. In the jsfiddle the top textarea is your browser, copy that and:

Linux/macOS

Run echo $BROWSER_SDP | insertable-streams

Windows

1. Paste the SessionDescription into a file.
2. Run insertable-streams < my_file

Input insertable-streams's SessionDescription into your browser

Copy the text that insertable-streams just emitted and copy into second text area

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

A video should start playing in your browser above the input boxes. insertable-streams will exit when the file reaches the end.

To stop decrypting the stream uncheck the box and the video will not be viewable.

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