This is a program to cast your **macOS** audio, or **Linux** audio to your

Google Cast devices or Sonos speakers. It can also [cast video files](#video).



It is written for Python3, and it can stream via `node.js`, `parec` (**Linux**),

or `ffmpeg`.  **Mkchromecast** is capable of using lossy and lossless audio

formats provided that `ffmpeg` or `parec` (**Linux**) are installed. It also

supports [Multi-room group

playback](https://support.google.com/chromecast/answer/6329016?hl=en), and

 [24-bit/96kHz high audio resolution](https://github.com/muammar/mkchromecast#high-quality-audio).

Additionally, a system tray menu is available.



By default, **Mkchromecast** streams with `node.js` (or `parec` in **Linux**)

together with `mp3` audio coding format at a sample rate of `44100Hz` and

average bitrate of `192k`.  These defaults can be changed using the

`--sample-rate` and `-b` flags. It is useful to modify these parameters when

your wireless router is not very powerful, or in the case you don't want to

degrade the sound quality. For more information visit the

[wiki](https://github.com/muammar/mkchromecast/wiki/), and the

[FAQ](https://github.com/muammar/mkchromecast/wiki/FAQ).



You can optionally install `ffmpeg` [more information

here](https://github.com/muammar/mkchromecast#using-the-ffmpeg-backend-with-mkchromecast-installed-from-sources)).

**Linux** users also can configure [ALSA to capture

audio](https://github.com/muammar/mkchromecast/wiki/ALSA).  Note that sometimes

the lag between playing a song and hearing may be up to 8 seconds for certain

backends.



Tell me more about it

----------------------

To have an idea of using **Mkchromecast** from console [check this

gif](https://github.com/muammar/mkchromecast#usage).



**Mkchromecast** provides a **beta** system tray menu. It requires you to

install `PyQt5`. For more information check the

[Requirements](https://github.com/muammar/mkchromecast#requirements) and

[Install](https://github.com/muammar/mkchromecast#install) sections.



This is what the system tray menu looks like:

Install

-------



There are two ways of installing this application:



1. Using the [binaries](https://github.com/muammar/mkchromecast#binaries).

2. From [sources](https://github.com/muammar/mkchromecast#from-sources).



#### Binaries



##### macOS



There is a standalone application for **macOS** users. You need to drag it to your

`/Applications/` folder.



[Download the latest dmg

here](https://github.com/muammar/mkchromecast/releases/latest/).

You need also to [install

BlackHole](https://github.com/muammar/mkchromecast#BlackHole-macos-users-only).



###### Homebrew Cask



If you are using homebrew,  it is possible to install the binary as follows:



```

brew install --cask mkchromecast

```



If you find any problem with the application, please [report it

here](https://github.com/muammar/mkchromecast/issues).



##### Linux



* Debian (.deb): [https://packages.debian.org/mkchromecast](https://packages.debian.org/mkchromecast).

* Ubuntu (.deb): [http://packages.ubuntu.com/search?keywords=mkchromecast](http://packages.ubuntu.com/search?keywords=mkchromecast).



**Mkchromecast** is available in the [official Debian

repositories](https://packages.debian.org/mkchromecast). To install

it, just do:



```

apt install mkchromecast

```



Download the latest [deb package

here](https://github.com/muammar/mkchromecast/releases/), and install it as

follows:



```

sudo apt -f install ./mkchromecast_$VERSION_all.deb

```



where `$VERSION = X.Y.Z-Rev`, _e.g._: `0.2.6-1`.



This should work in Debian Unstable and Testing. I would appreciate Ubuntu

testers as well. If you find any problems, please [report it

here](https://github.com/muammar/mkchromecast/issues).



If you experience other problems related to dependencies, please [discuss them

here](https://github.com/muammar/mkchromecast/issues/9) or open a new issue.



Additionally, there are two dependency packages for pulling pulseaudio or ALSA

dependencies:



```

apt-get install mkchromecast-alsa (ALSA users)

```



or



```

apt-get install mkchromecast-pulseaudio (Pulseaudio users)

```



#### From sources



To install **Mkchromecast**, clone this repository:



```

git clone https://github.com/muammar/mkchromecast.git --depth 1

```



Or you may download one of the [stable releases

here](https://github.com/muammar/mkchromecast/releases), and unzip the file.



##### Arch Linux



Mkchromecast is available at the AUR :

- Release version: [https://aur.archlinux.org/packages/mkchromecast/](https://aur.archlinux.org/packages/mkchromecast/).

- Development version: [https://aur.archlinux.org/packages/mkchromecast-git/](https://aur.archlinux.org/packages/mkchromecast-git/).



```bash

#install with aurman

aurman -S mkchromecast

```



```bash

#install with aurutils

aur sync mkchromecast

```



If you get the error `cannot import name 'DependencyWarning'` in Arch Linux,

please check issue [#31](https://github.com/muammar/mkchromecast/issues/31).



##### Python



To install python requirements use the `requirements.txt` file shipped in

this repository:



```

pip install -r requirements.txt

```



**Note**: if this step fails, maybe you need to run the installation with

`sudo` as shown below. However, before installing using this method verify why

a regular user cannot install these requirements.



```

sudo pip install -r requirements.txt

```



**Linux** users can try to install these python requirements using the package

managers coming with their distributions.



Example for Debian based distros:



```

sudo apt-get install python3.6 python3-pip python3-pychromecast python3-flask python3-psutil python3-setuptools python3-mutagen python3-gi vorbis-tools sox lame flac faac opus-tools

```



**Note**: if `python3-pychromecast` is not available in your repository,

follow instructions in [#9](https://github.com/muammar/mkchromecast/issues/9).



##### BlackHole (macOS users only)



For installing BlackHole you can check

[https://github.com/ExistentialAudio/BlackHole ](https://github.com/ExistentialAudio/BlackHole)

and just download the [latest dmg

file](https://github.com/ExistentialAudio/BlackHole/releases).



If you have [Homebrew](http://brew.sh/) you can use [brew

cask](https://caskroom.github.io/) as follows:



```

brew install --cask blackhole

```



By default, the sample rate in BlackHole is set to `44100Hz`. If you desire

to stream at higher sample rates follow the [instructions in the

wiki](https://github.com/muammar/mkchromecast/wiki/Sample-rates).



**Note**: re-sampling to higher sample rates is not a good idea. It was indeed

an issue in chromecast audio devices. See [this thread](https://goo.gl/yNVODZ).

Therefore, if you want to go beyond `44100Hz` you have to [capture the sound at

a higher sample rate](https://github.com/muammar/mkchromecast/wiki/Sample-rates).



##### ffmpeg



The easiest way of installing `ffmpeg` is using a package manager, *e.g.*: brew,

macports or fink. Or in the case of **Linux**, *e.g.*: apt, yum, or pacman.



###### macOS



I will briefly describe the case of Homebrew here. First, you will need

Homebrew installed in your machine:



```

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

```



Once Homebrew is ready, you can install `ffmpeg`.  As stated in the [ffmpeg

website](https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX), and for being

able to use all audio coding formats in **Mkchromecast**, it is better to

install `ffmpeg` with the following options enabled:



```

brew install ffmpeg --with-fdk-aac --with-tools --with-freetype --with-libass --with-libvorbis --with-libvpx --with-x265 --with-opus

```



###### Linux



As I use Debian, the way of installing `ffmpeg` is:



```

apt-get install ffmpeg

```



**Audio coding formats available with `parec` and `ffmpeg` backends**



**Audio coding format** | **Description**                   | **Notes**

------------------------| ----------------------------------|------------------

  `mp3`                 | MPEG Audio Layer III (default)    | Lossy compression format (default bitrate: 192k)

  `ogg`                 | Ogg Vorbis                        | Lossy compression format (default bitrate: 192k)

  `aac`                 | Advanced Audio Coding (AAC)       | Lossy compression format (default bitrate: 192k)

  `opus`                | Opus                              | Lossy compression format (default bitrate: 192k)

  `wav`                 | Waveform Audio File Format        | Lossless format (HQ sound)

  `flac`                | Free Lossless Audio Codec         | Lossless format (HQ sound)



##### PyQt5



These Python bindings are needed if you intend to use the system tray menu.

Sometimes `pip` is able to install `PyQt5` and`pip install pyqt5` is enough.



If this does not work for you, I suggest you to install it using a package

manager.



###### macOS



Example with Homebrew:



```

brew install pyqt5 --with-python3

```



###### Linux



* **Debian**



```

apt-get install python3-pyqt5

```



or if you desire it you can do it yourself from the sources.



Updating

--------



To update **Mkchromecast** sources, just get into the cloned directory and:



```

git pull

```



or if you prefer it, you can just pass the `--update` argument to

**Mkchromecast**:



```

bin/mkchromecast --update

```



If you are using the **macOS** application:



1. Click on `Check For Updates`.

2. If there are new versions, you will be prompted to [download the latest

   dmg](https://github.com/muammar/mkchromecast/releases/latest).

3. Replace the `mkchromecast.app` in your `/Applications/` directory.



**Linux** users need to either perform a `apt-get upgrade` or [download the

latest deb here](https://github.com/muammar/mkchromecast/releases/), and `dpkg

-i mkchromecast_$VERSION_all.deb`.



Usage

-----



#### Audio



Get into the cloned **Mkchromecast** directory and execute:



```

bin/mkchromecast

```



This will launch **Mkchromecast** using `node.js` (or `parec` for **Linux**

users), and will do the streaming part together with the `mp3` audio coding

format.  `node.js` works decently but the server may tend to _fail_ under certain

circumstances. In such a case, **Mkchromecast** is able to restart the

_streaming/casting_ process automatically. So, some hiccups are expected.



**Note**: most of the steps described herein are the same for **macOS** and **Linux**

users. However, if you launch the command above in **Linux**, the process is

less automatized.  In **Linux**, you need to select with `pavucontrol` the sink

called `Mkchromecast` to stream unless you are using [ALSA](https://github.com/muammar/mkchromecast/wiki/ALSA).

See the [wiki for more information](https://github.com/muammar/mkchromecast/wiki/Linux). tl;dr?, just

check the gif below.



![Example of using mkchromecast](https://raw.githubusercontent.com/muammar/mkchromecast/master/images/mkchromecast_linux.gif)



**Note**: the cast process is independent from the selection of the pulseaudio

sink. This means that **Mkchromecast** will tell the cast device to listen your

computer but no sound will be heard until you select the sink. For ALSA users, this

does not apply.



##### Using the `ffmpeg` backend with **Mkchromecast** installed from sources



Below an example using `mp3`:



```

bin/mkchromecast --encoder-backend ffmpeg

```



With `ffmpeg` you can modify the codec:



```

bin/mkchromecast --encoder-backend ffmpeg -c aac

```



change the bitrate and sample rate:



```

bin/mkchromecast --encoder-backend ffmpeg -c mp3 -b 128 --sample-rate 31000

```



check the section [BlackHole (macOS users

only)](https://github.com/muammar/mkchromecast#BlackHole-macos-users-only)

for more about sample rates.



You also can set the host ip manually which is a useful option when having more

than one active network connection or when the automatically ip detection fails:



```

bin/mkchromecast --host 192.168.1.1

```



##### Other examples with **Mkchromecast** installed using the debian package



To cast using `parec` and `wav` audio coding format:

```

mkchromecast -c wav

```



There is also an option to change the `bitrate`, and in this case with `ffmpeg`:



```

mkchromecast --encoder-backend ffmpeg -c ogg -b 128

```



and another one to change the sampling rate:



```

mkchromecast --encoder-backend ffmpeg -c ogg -b 128 --sample-rate 48000

```



##### Using **Mkchromecast** from the system tray



To launch it:



```

bin/mkchromecast -t

```

or



```

mkchromecast -t

```



The system tray application can perform all the actions from the aforementioned

commands. To get an idea, please check the [Youtube video

here](https://github.com/muammar/mkchromecast#macos).



#### Playing Youtube URLs in Google Cast devices



You can play Youtube URLs (or [other

sites](https://rg3.github.io/youtube-dl/supportedsites.html) headlessly from

the command line:



```

bin/mkchromecast -y https://www.youtube.com/watch\?v\=NVvAJhZVBT

```



To use this function, you need to install `youtube-dl`. In macOS, this can be

done with homebrew: `brew install youtube-dl`. In Debian based distros:

`apt-get install youtube-dl`.



**Note**: you may need to enclose the URL between quotation marks, and only

URLs over `https` are supported.



#### Playing source URLs in Google Cast devices



You can play any source URLs headlessly from the command line:



```

bin/mkchromecast --source-url SOURCE_URL

```



This option is useful for:



1. Casting using MPD in the case you have already a `http` streaming source.

2. Casting a radio station. A list of stations to try: https://ponyvillefm.com/servers



Example:



```

bin/mkchromecast --source-url http://192.99.131.205:8000/pvfm1.ogg -c ogg --control



```



As it can be seen above, **the codec has to be specified with the `-c` flag**.



**Note**: `.m3u` or `.pls` are not yet supported.



#### Controlling the Google Cast's volume and pause/resume options



You can control the volume of your Google Cast device by launching

**Mkchromecast** with the option `--control`:



```

bin/mkchromecast --encoder-backend ffmpeg -c ogg -b 320 --control

```



This will allow you to press u and d keys for `volume up`

and `volume down` respectively.



The system tray has a window with a volume slider to do `volume up` and `volume down`.



#### High quality audio



**Mkchromecast** lets you cast using `24-bit/96kHz` high audio resolution. This

is the *maximum chromecast audio capability*. The supported codecs are: `wav`

and `flac`. In spite of the fact that `aac` can use `96000Hz` sample rate, the

bitrate corresponds to that of a lossy data compression format. Therefore, the

following combinations can achieve this `24-bit/96kHz` capability:



* `wav` + `96000Hz` sample rate.

* `flac` + `96000Hz` sample rate.



References:

* [#11](https://github.com/muammar/mkchromecast/issues/11).

* [Lossless formats](https://github.com/muammar/mkchromecast/wiki/Audio-Quality#lossless-formats).



#### Video



You can now cast videos to your Google cast using **Mkchromecast**. This feature works both with `node`

and `ffmpeg` backends and from command line. In the future, they may be a graphical interface

for this process. [See this project](https://github.com/muammar/mkchromecast/projects/1).



* Cast a file from your computer to your chromecast:



```

bin/mkchromecast --video -i "/path/to/file.mp4"

```



```

bin/mkchromecast --video -i "/path/to/file.mp4" --encoder-backend node

```



**Note**: the format of the file can be whatever is supported by `ffmpeg` and not exclusively mp4.



* Subtitles



```

bin/mkchromecast --video -i "/tmp/Homeland.S06E01.Fair.Game.1080p.AMZN.WEBRip.HEVC.DD5.1.x265.mkv" --subtitles /tmp/Homeland.S06E01.Fair\ Game.HDTV.x264-BATV.en.HI.srt

```



* Set the resolution



```

bin/mkchromecast --video --resolution 4k -i /path/to/myvideo.something --subtitles /path/to/my.srt

```



* Cast from a source url:



```

bin/mkchromecast --source-url http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4 -c mp4 --volume --video

```



* Youtube Video



```

bin/mkchromecast -y https://www.youtube.com/watch\?v\=VuMBaAZn3II --video

```



Killing the application

-----------------------



To kill **Mkchromecast** when you run it from console, just press

Ctrl-C or q key to quit (when `--control` flag is passed).



When launching from system tray, use the `Quit` button in the system tray.



More help

---------



To get more help:



```

bin/mkchromecast -h

```



or when installing the debian package:



```

mkchromecast -h

```



Known issues

------------

##### General



* **Mkchromecast**'s versions lower than 0.3.7 cannot operate with newer

  versions of pychromecast.

* When casting videos using the `node` backend, it is not possible to

  use neither the `--subtitle` nor the `--seek` flags.

* When casting to Sonos the only codecs supported are: `mp3`, and `aac`.

  I won't give `wma` support. Apparently there is a way to play `wav`, and

  `ogg` that I will try to implement later.



##### macOS



* **Mkchromecast** v0.3.6 cannot connect to selected chromecast when there are

  more than one available. In that case, you need to use the application from

  sources or build the application as shown

  [here](https://github.com/muammar/mkchromecast/wiki/macOS-standalone-app).



##### Linux



* When using `parec` and `lame` encoder, the delay between audio played and

  listened can be up to 8 seconds. I suggest you to use something different

  than mp3.



You can also check the [FAQ](https://github.com/muammar/mkchromecast/wiki/FAQ)

for more information.



TODO

----



* Verify all exceptions when the system tray menu fails.

* **Sonos**: add support to different available flags.

* **Sonos**: add Equalizer in the controls.
