WebRTC Capture Proof of Concept

This is a simple proof of concept of how a H264 stream can be captured by webrtc-rs and converted into a bitmap if the first packet contains a h264 frame (or something like that).

It does not work reliably because sometimes the first packet does not always contain the information needed but it should be enough to get started on a working solution.

The docs bellow are copy and pasted from the webrtc-rs example this is based on:

save-to-disk-h264

save-to-disk-h264 is a simple application that shows how to record your webcam/microphone using WebRTC.rs and save H264 and Opus to disk.

Instructions

Build save-to-disk-h264

cargo build --example save-to-disk-h264

Open save-to-disk example page

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

Run save-to-disk-h264, with your browsers SessionDescription as stdin

In the jsfiddle the top textarea is your browser, copy that and:

Linux/macOS

Run echo $BROWSER_SDP | ./target/debug/examples/save-to-disk-h264

Windows

1. Paste the SessionDescription into a file.
2. Run ./target/debug/examples/save-to-disk-h264 < my_file

Input save-to-disk-h264's SessionDescription into your browser

Copy the text that save-to-disk-h264 just emitted and copy into second text area

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

In the folder you ran save-to-disk-h264 you should now have a file output.h264 play with your video player of choice!

Congrats, you have used WebRTC.rs!
