# 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 encyption, 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
|
|
```
|
|
export GO111MODULE=on
|
|
go get github.com/pion/webrtc/v3/examples/insertable-streams
|
|
```
|
|
|
|
### Open insertable-streams example page
|
|
[jsfiddle.net](https://jsfiddle.net/t5xoaryc/) 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.
|
|
1. 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.
