The easiest way to build the webrtc plugin and all the plugins it needs, is to [use Cerbero](https://gstreamer.freedesktop.org/documentation/installing/building-from-source-using-cerbero.html). These instructions should work out of the box for all platforms, including cross-compiling for iOS and Android.
|
||||
|
||||
One thing to note is that it's written in Python 2, so you may need to replace all instances of `./cerbero-uninstalled` (or `cerbero`) with `python2 cerbero-uninstalled` or whatever Python 2 is called on your platform.
|
||||
|
||||
## Building GStreamer manually from source
|
||||
|
||||
For hacking on the webrtc plugin, you may want to build manually using the git repositories:
|
||||
|
||||
- http://gitlab.freedesktop.org/gstreamer/gstreamer
|
||||
- http://gitlab.freedesktop.org/gstreamer/gst-plugins-base
|
||||
- http://gitlab.freedesktop.org/gstreamer/gst-plugins-good
|
||||
- http://gitlab.freedesktop.org/gstreamer/gst-plugins-bad
|
||||
- http://gitlab.freedesktop.org/libnice/libnice
|
||||
|
||||
Or with Meson gst-build:
|
||||
|
||||
https://gitlab.freedesktop.org/gstreamer/gst-build/
|
||||
|
||||
You may need to install the following packages using your package manager:
|
||||
|
||||
json-glib, libsoup, libnice, libnice-gstreamer1 (the gstreamer plugin for libnice, called gstreamer1.0-nice Debian)
|
||||
|
||||
### Ubuntu 18.04
|
||||
|
||||
Here are the commands for Ubuntu 18.04.
|
||||
|
||||
```
|
||||
sudo apt-get install -y gstreamer1.0-tools gstreamer1.0-nice gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-plugins-good libgstreamer1.0-dev git libglib2.0-dev libgstreamer-plugins-bad1.0-dev libsoup2.4-dev libjson-glib-dev
|
||||
```

||||

||||
For hacking on the webrtc plugin, you may want to build manually using the git repositories:

|

- http://cgit.freedesktop.org/gstreamer/gst-plugins-bad
|
||||
- http://cgit.freedesktop.org/libnice/libnice
|
||||
|
||||
You can build these with either Autotools gst-uninstalled:

## Filing bugs
|
||||
|
||||
Please only file bugs about the demos here. Bugs about GStreamer's WebRTC implementation should be filed on the [GStreamer bugzilla](https://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer&component=gst-plugins-bad).
|
||||
Please only file bugs about the demos here. Bugs about GStreamer's WebRTC implementation should be filed on the [GStreamer gitlab](https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/new).

## Examples
|
||||
|
||||
### Building
|
||||
|
||||
Most of the examples that require a build process can be built using the meson build system in the top-level gst-examples directory by using the following commands:
|
||||
|
||||
```console
|
||||
cd /path/to/gst-examples
|
||||
meson _builddir
|
||||
ninja -C _builddir
|
||||
```
|
||||
|
||||
Build outputs will be placed in the directory `_builddir`.
|
||||
|
||||
### sendrecv: Send and receive audio and video
|
||||
|
||||

#### Running the C version

$ gcc webrtc-sendrecv.c $(pkg-config --cflags --libs gstreamer-webrtc-1.0 gstreamer-sdp-1.0 libsoup-2.4 json-glib-1.0) -o webrtc-sendrecv
|
||||
```
|
||||
|
||||
* Run `webrtc-sendrecv --peer-id=ID` with the `id` from the browser. You will see state changes and an SDP exchange.

### multiparty-sendrecv: Multiparty audio conference with N peers
|
||||
|
||||
* Build the sources in the `gst/` directory on your machine
|
||||
|
||||
```console
|
||||
$ gcc mp-webrtc-sendrecv.c $(pkg-config --cflags --libs gstreamer-webrtc-1.0 gstreamer-sdp-1.0 libsoup-2.4 json-glib-1.0) -o mp-webrtc-sendrecv
|
||||
```
|
||||
|
||||
* Run `mp-webrtc-sendrecv --room-id=ID` with `ID` as a room name. The peer will connect to the signalling server and setup a conference room.
|
||||
* Run `_builddir/multiparty-sendrecv/gst/mp-webrtc-sendrecv --room-id=ID` with `ID` as a room name. The peer will connect to the signalling server and setup a conference room.
|
||||
* Run this as many times as you like, each will spawn a peer that sends red noise and outputs the red noise it receives from other peers.
|
||||
- To change what a peer sends, find the `audiotestsrc` element in the source and change the `wave` property.
|
||||
- You can, of course, also replace `audiotestsrc` itself with `autoaudiosrc` (any platform) or `pulsesink` (on linux).
