The `gstreamer` platform allows you to play audio via a [gstreamer](https://gstreamer.freedesktop.org/) pipeline. Practically, this means you can play audio directly on the computer running Home Assistant. It is particularly suited for playing TTS. Advanced users can specify a pipeline to transform the audio stream and/or redirect it elsewhere.

To add a `gstreamer` media player to your installation, add the following to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
media_player:
  - platform: gstreamer
```

Configuration variables:

- **name** (*Optional*): Name the player.
- **pipeline** (*Optional*): `gst` pipeline description.

Only the `music` media type is supported.

## {% linkable_title Setup %}

And then install the following system dependencies:

Debian/Ubuntu/Rasbian:

```bash
sudo apt-get install python3-gst-1.0 \
    gir1.2-gstreamer-1.0 gir1.2-gst-plugins-base-1.0 \
    gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly \
    gstreamer1.0-tools
```

Red Hat/Centos/Fedora:

```bash
sudo yum install -y python-gstreamer1 gstreamer1-plugins-good \
    gstreamer1-plugins-ugly
```

For Fedora replace `yum` with `dnf`.

If you're running Home Assistant in a virtual environment, you'll need to symlink the system Python's `gi` module into your virtual environment:

```bash
ln -s /path/to/your/installation/of/gi /path/to/your/venv/lib/python3.4/site-packages
``` 

On a Raspberry PI, you may need to add the Home Assistant user to the `audio` group:

```bash
sudo usermod -a -G audio <ha_user>
```

## {% linkable_title Example Usage %}
 
### {% linkable_title Using with TTS %}

To play TTS on your local computer (for example, if you have speakers attached to your Raspberry PI:

```yaml
media_player:
  - platform: gstreamer

script:
  tts:
    sequence:
      - service: tts.google_say # or amazon_polly, voicerss, etc
        data:
          entity_id: media_player.gstreamer
          message: "example text-to-speech message"
```

### {% linkable_title Using with Snapcast %}

To play to a named pipe for consumption by Snapcast:

```yaml
media_player:
  - platform: gstreamer
    pipeline: "audioresample ! audioconvert ! audio/x-raw,rate=48000,channels=2,format=S16LE ! wavenc ! filesink location=/tmp/snapcast_gstreamer"
```
