Nine Years of Almost: My Raspberry Pi Love and Hate Journey

Описание и применение

Автор описывает, как после перехода на libvlc и исправлений Qt WebEngine, его приложение garlic‑player теперь стабильно воспроизводит 4K и HD видео с веб‑виджетами на Raspberry Pi 4 и 5.

Задача

Raspberry Pi hardware and software limitations hindered smooth, multi‑zone digital signage playback, especially with webviews and 4K video.

Результат

The updated garlic‑player achieves stable, smooth multi‑zone digital signage on Raspberry Pi 4 and 5, overcoming previous hardware acceleration and webview crashes.

Рабочий процесс

• 1. Replace FFmpeg/QtMultimedia with libvlc backend in garlic‑player.
• 2. Apply Qt WebEngine and WebView fixes for Raspberry Pi OS (Bookworm/Trixie).
• 3. Build and run the updated garlic‑player on Pi 4/5 with a standard SD card.
• 4. Verify multi‑zone layout with video and HTML5 widgets works without crashes.
• 5. Deploy via official AppImage for ease of installation.

Доказательства

garlic‑player on Linux ARM now uses libvlc as its multimedia backend instead of FFmpeg and QMultimedia.
