5### Create IVF named `output.ivf` that contains a VP8 track and/or `output.ogg` that contains a Opus track
6```
7ffmpeg -i $INPUT_FILE -g 30 output.ivf
8ffmpeg -i $INPUT_FILE -c:a libopus -page_duration 20000 -vn output.ogg

11### Download play-from-disk
12```
13export GO111MODULE=on
14go get github.com/pion/webrtc/v3/examples/play-from-disk
15```
16
17### Open play-from-disk example page
18[jsfiddle.net](https://jsfiddle.net/9s10amwL/) you should see two text-areas and a 'Start Session' button
19
20### Run play-from-disk with your browsers SessionDescription as stdin
21The `output.ivf` you created should be in the same directory as `play-from-disk`. In the jsfiddle the top textarea is your browser, copy that and:
22
23#### Linux/macOS
24Run `echo $BROWSER_SDP | play-from-disk`
25#### Windows
261. Paste the SessionDescription into a file.
271. Run `play-from-disk < my_file`
28
29### Input play-from-disk's SessionDescription into your browser
30Copy the text that `play-from-disk` just emitted and copy into second text area
31
32### Hit 'Start Session' in jsfiddle, enjoy your video!
33A video should start playing in your browser above the input boxes. `play-from-disk` will exit when the file reaches the end
