play-from-disk-mkv

play-from-disk-mkv demonstrates how to send video and/or audio to your browser from a MKV file

This example has the same structure as play-from-disk but instead reads from a MKV file

Instructions

Create a MKV with a H264 + Opus track

ffmpeg -i $INPUT_FILE -c:v libx264 -b:v 2M -max_delay 0 -bf 0 -g 30 -c:a libopus -page_duration 20000 output.mkv

Download play-from-disk-mkv

go install github.com/pion/example-webrtc-applications/v3/play-from-disk-mkv@latest

Open play-from-disk-mkv example page

jsfiddle.net you should see two text-areas and a 'Start Session' button

Run play-from-disk-mkv with your browsers SessionDescription as stdin

The output.mkv you created should be in the same directory as play-from-disk-mkv. In the jsfiddle the top textarea is your browser, copy that and:

Linux/macOS

Run echo $BROWSER_SDP | play-from-disk-mkv

Windows

  1. Paste the SessionDescription into a file.
  2. Run play-from-disk-mkv < my_file

Input play-from-disk-mkv's SessionDescription into your browser

Copy the text that play-from-disk-mkv 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. play-from-disk-mkv will exit when the file reaches the end

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