Cast All The Things allows you to send videos from many, many online sources (YouTube, Vimeo, and a few hundred others) to your Chromecast. It also allows you to cast local files or render websites.
You can install Cast All The Things with pip:
pip3 install catt
catt is only compatible with Python 3. If you need a Python 2-compatible
version, please install 0.5.6, the last py2-compatible release.
To use Cast All The Things, just specify a URL:
catt cast "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
catt supports any service that youtube-dl supports, which includes most online
video hosting services.
catt can also cast local files (if they're in a format the Chromecast supports
natively):
catt cast ./myvideo.mp4
You can also control your Chromecast through catt commands, for example with
catt pause. Try running catt --help to see the full list of commands.
If you have subtitles and the name is similar to the name of the local file, catt will add them automatically.
You can, of course, specify any other subtitle if you want. Although Chromecast only supports WEBVTT,
TTML and Line 21 subtitles, catt conveniently converts SRTs to WEBVTT for you on the fly. Here is how to use it:
catt cast -s ./mysubtitle.srt /myvideo.mp4
catt can also tell your Chromecast to display any website:
catt cast_site https://en.wikipedia.org/wiki/Rickrolling
Please note that the Chromecast has a slow CPU but a reasonably recent version of Google Chrome. The display resolution is 1280x720.
If you want to pass youtube-dl options to catt through the -y command-line flag, you need to use youtube-dl's internal option name, rather than its command-line name.
If you notice that catt stops working with video sites (YouTube, Vimeo, etc), just upgrade youtube-dl with pip install -U youtube-dl and that will probably fix it. This is because sites keep changing and youtube-dl is updated very regularly to keep them all working.
You can also run catt in Docker, if you prefer:
docker run -i -t python:3.7 /bin/bash -c "pip install catt; catt cast 'https://www.youtube.com/watch?v=dQw4w9WgXcQ'"
CATT can utilize a config-file stored at ~/.config/catt/catt.cfg (%APPDATA%\catt\catt.cfg on Windows).
The format is as following:
[options] device = chromecast_one [aliases] one = chromecast_one two = chromecast_two
In the [options] section, device denotes the default device that will
be selected, when you have not selected a device via the cli.
You can write your choice of default device to catt.cfg by doing:
catt -d <name_of_chromecast> set_default
In the [aliases] section, you can specify aliases for the names of your
chromecasts. You can then select a device just by doing:
catt -d <alias> <command>
You can write an alias name for a device to catt.cfg by doing:
catt -d <name_of_chromecast> set_alias <alias>
If you want to contribute a feature to catt, please open an issue (or comment on
an existing one) first, to make sure it's something that the maintainers are
interested in. Afterwards, just clone the repository and hack away!
To run catt in development, you can use the following command:
python -m catt.cli --help
Before committing, please make sure you install pre-commit and install its hooks:
pip install pre-commit pre-commit install
That's all, now you can commit and the hooks will run. Black (which is used to format the code) requires Python 3.6 to run, but please make the effort, as our CI will yell at you if the code is not formatted, and nobody wants that.
Thanks!
