Chromecast With Google Tv

After pairing once, you can use the connection port shown on the Wireless debugging screen for all other commands.

Capabilities

This skill provides a small CLI wrapper around ADB to control a Google TV device. It exposes the following subcommands:

• pair: pair with Chromecast using wireless debugging (first-time setup)
• status: show adb devices output
• play <query_or_id_or_url>: play content via YouTube, Tubi, or global-search fallback.
• pause: send media pause
• resume: send media play

Usage examples

./run pair --show-instructions

./run pair --pairing-ip 192.168.1.100 --pairing-port 12345 --pairing-code 123456

./run status --device 192.168.4.64 --port 5555

./run play "7m714Ls29ZA" --device 192.168.4.64 --port 5555

./run play "family guy" --app hulu --season 3 --episode 4 --device 192.168.4.64 --port 5555

./run pause --device 192.168.4.64 --port 5555

Device selection and env overrides

• You can pass --device (IP) and --port on the CLI.
• Alternatively, set CHROMECAST_HOST and CHROMECAST_PORT environment variables to override defaults.
• If you provide only --device or only --port, the script will use the cached counterpart when available; otherwise it will error.
• The script caches the last successful IP:PORT to .last_device.json in the skill folder and will use that cache if no explicit device is provided.
• If no explicit device is provided and no cache exists, the script will attempt ADB mDNS service discovery and use the first IP:PORT it finds.
• IMPORTANT: This skill does NOT perform any port probing or scanning. It will only attempt an adb connect to the explicit port provided or the cached port.

YouTube handling

• If you provide a YouTube video ID or URL, the skill will launch the YouTube app directly via an ADB intent restricted to the YouTube package.
• The skill attempts to resolve titles/queries to a YouTube video ID using the yt-api CLI (in the PATH). If ID resolution fails, the skill will report failure.
• You can override the package name with YOUTUBE_PACKAGE (default com.google.android.youtube.tv).

Tubi handling

• If you provide a Tubi https URL, the skill will send a VIEW intent with that URL (restricted to the Tubi package).
• If the canonical Tubi https URL is needed, the skill can look it up via web_search and supply it to this skill.
• You can override the package name with TUBI_PACKAGE (default com.tubitv).

Global-search fallback for non-YouTube/Tubi

• If YouTube/Tubi resolution does not apply and you pass --app with another provider (for example hulu, max, disney+), the skill uses a Google TV global-search fallback.
• For this fallback, pass all three: --app, --season, and --episode.
• scrcpy must be installed and available in the PATH for this flow.
• The fallback starts android.search.action.GLOBAL_SEARCH, waits for the Series Overview UI, opens Seasons, picks season/episode, then confirms Open in <app> when available.
• Hulu profile-selection logic is intentionally not handled here.

Pause / Resume

./run pause ./run resume

Dependencies

• The script uses only the Python standard library (no pip packages required).
• The scripts run through uv to avoid PEP 668/system package constraints.
• The script expects adb, scrcpy, uv, and yt-api to be installed and available in the PATH.

Caching and non-destructive defaults

• The script stores the last successful device (ip and port) in .last_device.json in the skill folder.
• It will not attempt port scanning; this keeps behavior predictable and avoids conflicts with Google's ADB port rotation.

Troubleshooting

• If adb connect fails, run adb connect IP:PORT manually from your host to verify the current port.
• If adb connect is refused and you're running interactively, the script will prompt you for a new port and update .last_device.json on success.
• Connection refused after pairing: If connection is refused:
  • Verify Wireless debugging is still enabled on the Chromecast
  • The device may need to be re-paired if it was restarted or Wireless debugging was toggled off
  • The interactive prompt will offer options to retry with a different port or re-pair
  • Use ./run pair --show-instructions for detailed setup steps

Implementation notes

• The skill CLI code lives in google_tv_skill.py in this folder. It uses subprocess calls to adb, scrcpy, and yt-api, plus an internal global-search helper for fallback playback.
• For Tubi URL discovery, the assistant uses web_search to find canonical Tubi pages and pass the https URL to the skill.
