A high-performance desktop application for watching Coachella livestreams with a perfectly synced, interactive schedule. Built with Python, PySide6, and mpv.

• Interactive Schedule: A programmatically rendered, scrollable grid showing the full lineup across all 7 stages.
• Multi-Day Support: Switch between Friday, Saturday, and Sunday schedules using tabs.
• Live Time Tracking: A precise red timeline that indicates exactly who is playing right now in Pacific Daylight Time (PDT).
• Column-Based Navigation: Click anywhere on a stage's column to instantly switch the video player to that stream.
• Automated Sync: One-command synchronization that fetches the latest artist schedule directly from official YouTube descriptions.
• Stream Recording: Press the R key while the video window is focused to start or stop recording the current stream to a local file. HLS playback records to .ts; 1440p and 4K SABR playback records to .mkv. A blinking "🔴 RECORDING" indicator will appear on the schedule timeline.
• Native Performance: Uses mpv as the video backend for low-latency, high-quality streaming.

• Python 3.9+
• mpv player: The application requires libmpv to be installed on your system.
  • Arch Linux: sudo pacman -S mpv
  • Ubuntu/Debian: sudo apt install mpv libmpv-dev
  • macOS: brew install mpv
• FFmpeg: Required for 1440p and 4K YouTube SABR livestream playback. The app uses the bundled yt-dlp_sabr downloader to fetch SABR fragments, then uses ffmpeg to mux the separate live video and audio fragments into a stream that mpv can play.
  • Arch Linux: sudo pacman -S ffmpeg
  • Ubuntu/Debian: sudo apt install ffmpeg
  • macOS: brew install ffmpeg

1. Clone and Setup Environment:

   python -m venv venv
   source venv/bin/activate  # On Windows use: venv\Scripts\activate
   pip install -r requirements.txt

To automatically download the latest descriptions, sync the schedule, and launch the app in one command:

python main.py

• Quality Selection: Auto, 1080p, and 720p use the standard HLS playback path. 1440p and 4K use the bundled SABR-enabled yt-dlp fork plus FFmpeg.
• Switch Stages: Click on any column in the schedule grid.
• Switch Days: Click the tabs at the top (aligned with the stage columns).
• Fullscreen: Toggle fullscreen in the video player using the F key or double-click.
• Recording: Press R in the video window to start/stop saving the stream to a local file.

The application is entirely data-driven. To update stream URLs or stage colors for future years, simply edit config.json.

• Library Errors on Linux: The app includes a bootstrap loader that handles Qt library version conflicts common on rolling-release distros (like Arch).
• Timezone: The app uses America/Los_Angeles (PDT) for the timeline regardless of your local system time, matching the official festival schedule.
