# Stream an audio cd to a chromecast
We will use an icecast server, to install it:
```bash
$ sudo apt-get install icecast2
```
Icecast2 server will broadcast the audio feed
And we need ffmpeg, which will stream audio cd to icecast2 feed:
```bash
$ sudo apt-get install ffmpeg
```
Some configuration, for icecast2: edit the ``/etc/icecast2/icecast.xml`` file, and check the authentication part:
```xml
YOUR_PASSWORD
YOUR_PASSWORD
admin
YOUR_PASSWORD
```
And the hostname and socket part:
```xml
localhost
8000
```
You can see the full config file in the [Chromecast-audio-cd-caster repo](https://github.com/gpenverne/chromecast-audio-cd-caster)
To stream using ffmpeg, simply use:
```bash
/usr/bin/ffmpeg -f libcdio -ss 0 -i /dev/cdrom -acodec libmp3lame -ab 48k -bufsize 15 -ac 1 -content_type audio/mpeg -f mp3 icecast://source:[email protected]:8000/raspi
```
(Don't forget to replace 192.168.0.31 by your raspberry pi local ip)
You have now a feed readable from http://192.168.0.31:8000/raspi
### How to cast?
To cast what you want to a chromecast, have a look on [Pychromecast](https://github.com/balloob/pychromecast)
Of course, you need python3:
```bash
$ sudo apt-get install python3
```
And a tiny python script:
```python
import time
import pychromecast
import urllib.request
stream_url = 'http://192.168.0.31:8000/raspi'
chromecasts = pychromecast.get_chromecasts()
cast = next(cc for cc in chromecasts if cc.device.friendly_name == "Salon")
cast.wait()
print(cast.device)
print(cast.status)
mc = cast.media_controller
while urllib.request.urlopen(stream_url).getcode() != 200:
print('Waiting for stream up')
time.sleep(1)
mc.play_media(stream_url, 'audio/mp3')
mc.block_until_active()
print(mc.status)
mc.play()
```
And ... it's a kind of magic:
```bash
$ /usr/bin/ffmpeg -f libcdio -ss 0 -i /dev/cdrom -acodec libmp3lame -ab 48k -bufsize 15 -ac 1 -content_type audio/mpeg -f mp3 icecast://source:[email protected]:8000/raspi & /usr/bin/python3 /home/pi/audio/cast.py
```
### Bonus: autostart on cd insertion
We will use an udev rule, for example in a ``/etc/udev/rules.d/99-cd-audio-processing.rules`` rule:
```
SUBSYSTEM=="block", KERNEL=="sr0", ACTION=="change", RUN+="/home/pi/audio/start-cd.sh &"
```
Reboot, and you're ready :)
