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 encyption, add metadata or insert a completely different video feed!
ffmpeg -i $INPUT_FILE -g 30 output.ivf
export GO111MODULE=on
go get github.com/pion/webrtc/v3/examples/insertable-streams
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.
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:
Run echo $BROWSER_SDP | insertable-streams
- Paste the SessionDescription into a file.
- Run
insertable-streams < my_file
Copy the text that insertable-streams
just emitted and copy into second text area
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
