How It Works
YouTube App Cast works by using a combination of protocols to discover and control your TV app. It starts by searching for DIAL enabled devices on your local network using SSDP, a protocol part of UPnP.
The discovery part of DIAL is performed using SSDP, which is part of UPnP. This is how your phone finds your TV on the network.
Once it finds the TV, it gets the state of the YouTube on TV app on the target device using DIAL. If the app is stopped, it starts it using DIAL.

Here's a step-by-step overview of the process:
- Search DIAL enabled devices on the local network (SSDP)
- Get the state of the YouTube on TV app on the target device (DIAL)
- Start the app if it's stopped (DIAL)
- Get the screenId of the app (DIAL)
- Get a token for that screenId (Lounge)
- Call the api's "play video endpoint" passing the token and the video urls to play (Lounge)
This process is made possible by the YouTube Lounge api, which is used by Chrome and the YouTube smartphone app to remotely control the YouTube on TV app.
Usage
To use ytcast effectively, the computer and target device must be on the same network. This is a crucial requirement, as it allows for seamless communication between the two devices.
The target device must support the DIAL protocol, which is a specific technology that enables device discovery and communication. This is a necessary condition for ytcast to work.
The target device must also have the YouTube on TV app already installed, which is a prerequisite for casting videos.
If your target device doesn't show up in the list of available devices, you can try increasing the search timeout with the -t (timeout) option. This gives the device more time to respond to the query.

To cast to the last used device, simply use the -p option. This is a convenient feature that saves you time and effort.
If you want to see what's going on under the hood, use the -verbose option. This provides detailed information about the process, which can be helpful when troubleshooting issues.
Here are the basic options for running ytcast:
Keep in mind that if you use the -pair option, you'll need to manually specify the device, which can add some limitations to the process. However, this can be a useful workaround if you're experiencing issues with device discovery.
How It Works
Here's how it works:
The DIAL protocol is the key to discovering and launching apps on your TV. It's developed by Netflix and Google, and it uses the SSDP (Simple Service Discovery Protocol) to perform the discovery part.
DIAL is part of the UPnP (Universal Plug and Play) protocol, which helps devices on your network communicate with each other.

To play a video on your TV, you need to use the YouTube Lounge API, which is used by Chrome and the YouTube smartphone app to remotely control the YouTube on TV app.
The API is not documented, but luckily, many people have already reverse-engineered it, so we can use it to control the YouTube on TV app.
Here's the step-by-step process of how it works:
- Search for DIAL-enabled devices on the local network using SSDP.
- Get the state of the YouTube on TV app on the target device using DIAL.
- Start the YouTube on TV app if it's stopped using DIAL.
- Get the screenId of the app using DIAL.
- Get a token for that screenId using the Lounge API.
- Call the API's "play video endpoint" passing the token and the video URLs to play using the Lounge API.
This process is done automatically by the ytcast app, which uses a "devices cache" to speed up the process and tries to wake up the target device if it's turned off using Wake-on-Lan.
