Playing Offline Music in Emacs with Ready Player Mode

Summary:

This video introduces Ready Player Mode, an Emacs package designed for offline music playback.

The speaker developed Ready Player Mode to reduce reliance on music streaming services by facilitating offline music playback directly within Emacs.
The package offers minimal configuration, an intuitive user interface, and allows opening music files just like any other file in Dired.
It leverages MPV for actual audio playback and Dired buffers to manage playlists and files.
Key features demonstrated include automatic playback, mouse and single-key shortcuts for controls (next, previous, shuffle), and browsing/searching a music collection.
The package also supports downloading album artwork and offers "semi-headless" operation, allowing users to control playback via keybindings without the player buffer in focus.

Playing Offline Music in Emacs [0:00:41]

The video begins by outlining the motivation behind Ready Player Mode, which is to play offline music directly within Emacs.

Backstory and Goal [0:00:44]
- The speaker aimed to reduce dependency on streaming services by purchasing music for offline playback.
- While still using streaming for discovery, the majority of music consumption is now offline and managed within Emacs.
- The primary goal of the episode is to demonstrate how to play these local music files.

Introducing Ready Player Mode [0:01:16]

Ready Player Mode is a custom Emacs package built by the speaker for offline music playback.

Design Principles [0:01:22]
- Minimal Configuration: Requires only a simple (require 'ready-player) and (ready-player-mode 1) to enable.

- Usable Out-of-the-Box: Designed to be functional immediately after installation.
- Intuitive UI: The user interface is straightforward, with familiar playback controls.
- Seamless File Opening: Music files can be opened in Dired just like any other file (e.g., .org files or images), triggering playback.
- Underlying Technologies: Playback is offloaded to mpv, and dired buffers are used to manage the list of files.

Demonstrating Core Functionality and UI [0:01:52]

The speaker provides a live demonstration of Ready Player Mode.

File Handling in Dired [0:01:52]
- When ready-player-mode is enabled, opening a media file (like .m4a or .mp3) in a Dired buffer will initiate playback and display the player interface, instead of showing garbled binary data.
- Other file types (e.g., .org, .png) open normally.
Player Interface [0:02:45]
- Upon opening a media file, the player automatically starts playing if autoplay is enabled.

- The interface includes standard controls like play/pause, next, previous, shuffle, and repeat.
- Users can interact with buttons using a mouse or navigate via tab, shift-tab, back-tab.
- Single-key shortcuts (e.g., n for next, s for shuffle) are also available.
- The player automatically detects media files in the current Dired directory and creates a playlist from them.
Flexibility of Dired Buffers [0:04:22]
- Ready Player Mode relies on Dired buffers as its source of files, making it highly flexible.
- Dired buffers can be created in various ways, such as using the find command-line utility or importing from playlist files, allowing users to craft custom playlists.

Advanced Features [0:04:45]

The video covers additional functionalities of Ready Player Mode for managing and interacting with music.

Music Collection Management [0:04:47]
- Users can set a global ready-player-music-collection-location variable to specify the root directory of their music library.
- A "home" button in the player UI opens a Dired buffer representing this entire collection.
- Shuffle Play: The speaker often uses shuffle mode for casual listening and toggles it off to stay within a particular artist's tracks.
Searching [0:05:36]
- Pressing / within the player or collection buffer opens a fuzzy search prompt (using consult) to find specific artists or songs.

- Selecting a search result opens its corresponding Dired buffer and starts playback.
Album Art Download [0:06:24]
- If a track lacks album art, users can invoke ready-player-download-album-artwork.
- The command prompts for a service (e.g., iTunes) to fetch the artwork and asks for confirmation to save it alongside the music file.

Semi-Headless Operation [0:07:18]
- Even if the Ready Player buffer is hidden, users can still control playback using global keybindings under the C-c m prefix.
- C-c m m toggles the player buffer to the foreground.
- C-c m n moves to the next track, and C-c m p moves to the previous track.
- When these commands are used without the buffer in focus, a temporary notification appears in the minibuffer displaying the current track info and album art before fading away.
