# mediasoup demo - RTP recording

In this example, a browser's webcam media is transmitted to [mediasoup](https://mediasoup.org/) using WebRTC ([WebRtcTransport](https://mediasoup.org/documentation/v3/mediasoup/api/#WebRtcTransport)); it is then served as a plain RTP stream ([PlainTransport](https://mediasoup.org/documentation/v3/mediasoup/api/#PlainTransport)) to be received and recorded by an external process.

**The media is not re-encoded at any moment**. This is an important detail, because you want recording to take as little resources as possible. For that, the FFmpeg and GStreamer commands are carefully written to make sure that the media packets are received via RTP and get stored as-is to the output recording file.



## Setup

_mediasoup_ applications are written for [Node.js](https://nodejs.org/), so you need to have it installed. Follow the [installation instructions](https://github.com/nodesource/distributions/blob/master/README.md) provided by NodeSource to install Node.js from an official repository; or just grab it from the official [downloads page](https://nodejs.org/en/download/).

You can choose between three recording programs:

- [GStreamer](https://gstreamer.freedesktop.org/).
- [FFmpeg](https://ffmpeg.org/). See [Recording with FFmpeg](#recording-with-ffmpeg).
- An external process.

Finally, read some [important notes](#important-notes) about recording and playback.

Hi both these projects are listed on examples page. I realize done by 3rd party developers but does anybody have any insight on how to make them run correctly on the gcp or azure?

I have used both Ubuntu 18.04LTS and 20.04LTS and still get the same issue. The webrtc connection is setup correctly on both sides. However when I go to hit record FFmpeg or GStreamer will always fail and create either a mp4 or v8 container that is zero bytes.

The sdp file looks fine to me and looking through the docs both libraries are following the correct procedure when creating a plainrtp transport so that RTP stream can be consumed by either FFmpeg or GStreamer. I have disabled all my firewall protections against the ports. I have used both GCP and Azure VMs and get the same issue.

Have you checked this?

The link you provided doesn’t open. Is there an alternative link I can use?

Is the webrtc transport ip in your config correct? Also you will most likely need to set “announcedIp”
