# rtp-to-webrtc
|
|
rtp-to-webrtc demonstrates how to consume a RTP stream video UDP, and then send to a WebRTC client.
|
|
|
|
With this example we have pre-made GStreamer and ffmpeg pipelines, but you can use any tool you like!
|
|
|
|
## Instructions
|
|
### Download rtp-to-webrtc
|
|
```
|
|
go install github.com/pion/webrtc/v4/examples/rtp-to-webrtc@latest
|
|
```
|
|
|
|
### Open jsfiddle example page
|
|
[jsfiddle.net](https://jsfiddle.net/z7ms3u5r/) you should see two text-areas and a 'Start Session' button
|
|
|
|
|
|
### Run rtp-to-webrtc with your browsers SessionDescription as stdin
|
|
In the jsfiddle the top textarea is your browser's SessionDescription, copy that and:
|
|
|
|
#### Linux/macOS
|
|
Run `echo $BROWSER_SDP | rtp-to-webrtc`
|
|
|
|
#### Windows
|
|
1. Paste the SessionDescription into a file.
|
|
1. Run `rtp-to-webrtc < my_file`
|
|
|
|
### Send RTP to listening socket
|
|
You can use any software to send VP8 packets to port 5004. We also have the pre made examples below
|
|
|
|
|
|
#### GStreamer
|
|
```
|
|
gst-launch-1.0 videotestsrc ! video/x-raw,width=640,height=480,format=I420 ! vp8enc error-resilient=partitions keyframe-max-dist=10 auto-alt-ref=true cpu-used=5 deadline=1 ! rtpvp8pay ! udpsink host=127.0.0.1 port=5004
|
|
```
|
|
|
|
#### ffmpeg
|
|
```
|
|
ffmpeg -re -f lavfi -i testsrc=size=640x480:rate=30 -vcodec libvpx -cpu-used 5 -deadline 1 -g 10 -error-resilient 1 -auto-alt-ref 1 -f rtp 'rtp://127.0.0.1:5004?pkt_size=1200'
|
|
```
|
|
|
|
If you wish to send audio replace all occurrences of `vp8` with Opus in `main.go` then run
|
|
|
|
```
|
|
ffmpeg -f lavfi -i 'sine=frequency=1000' -c:a libopus -b:a 48000 -sample_fmt s16p -ssrc 1 -payload_type 111 -f rtp -max_delay 0 -application lowdelay 'rtp://127.0.0.1:5004?pkt_size=1200'
|
|
```
|
|
|
|
If you wish to send H264 instead of VP8 replace all occurrences of `vp8` with H264 in `main.go` then run
|
|
|
|
```
|
|
ffmpeg -re -f lavfi -i testsrc=size=640x480:rate=30 -pix_fmt yuv420p -c:v libx264 -g 10 -preset ultrafast -tune zerolatency -f rtp 'rtp://127.0.0.1:5004?pkt_size=1200'
|
|
```
|
|
|
|
### Input rtp-to-webrtc's SessionDescription into your browser
|
|
Copy the text that `rtp-to-webrtc` 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.
|

Congrats, you have used Pion WebRTC! Now start building something cool
|
|
|
|
## Dealing with broken/lossy inputs
|
|
Pion WebRTC also provides a [SampleBuilder](https://pkg.go.dev/github.com/pion/webrtc/v3@v3.0.4/pkg/media/samplebuilder). This consumes RTP packets and returns samples.
|
|
It can be used to re-order and delay for lossy streams. You can see its usage in this example in [daf27b](https://github.com/pion/webrtc/commit/daf27bd0598233b57428b7809587ec3c09510413).
|
|
|
|
Currently it isn't working with H264, but is useful for VP8 and Opus. See [#1652](https://github.com/pion/webrtc/issues/1652) for the status of fixing for H264.
