**Syng** is an all-in-one karaoke software, consisting of a *backend server*, a *web frontend* and a *playback client*.
Karaoke performers can search a library using the web frontend, and add songs to the queue.
The playback client retrieves songs from the backend server and plays them in order.
You can play songs from **YouTube**, an **S3** storage or simply share local **files**.
The playback client uses [mpv](https://mpv.io/) for playback and can therefore play a variety of file formats, such as `mp3+cdg`, `webm`, `mp4`, ...
# Client
[](https://flathub.org/apps/rocks.syng.Syng)
To host a karaoke event, you only need to use the playback client. You can use the publicly available instance at https://syng.rocks as your server.
## Installation
### Linux
The preferred way to install the client is via [Flathub](https://flathub.org/apps/rocks.syng.Syng).
Alternatively Syng can be installed via the _Python Package Index_ (PyPI). When installing the client it is mandatory to include the `client` flag:
pip install 'syng[client]'
This installs both the playback client (`syng client`) and a configuration GUI (`syng gui`).
**Note:** When installing via PyPI, you need to have [mpv](https://mpv.io/) installed on the playback client, and the `mpv` binary must be in your `PATH`.
### Windows
Windows support is experimental, but you can download the current version from [Releases](https://github.com/christofsteel/syng/releases). No installation necessary, you can just run the `exe`.
## Configuration
You can host karaoke events using the default configuration. But if you need more advanced configuration, you can either configure Syng using the GUI or via a text editor by editing `~/.config/syng/config.yaml`. There are the following settings:
* `server`: URL of the server to connect to.
* `room`: The room code for your karaoke event. Can be chosen arbitrarily, but must be unique. Unused rooms will be deleted after some time. _Note:_ Everyone, that has access to the room code can join the karaoke event.
* `secret`: The admin password for your karaoke event. If you want to reconnect with a playback client to a room, these must match. Additionally, this unlocks admin capabilities to a web client, when given under "Advanced" in the web client.
* `waiting_room_policy`: One of `none`, `optional`, `forced`. When a performer wants to be added to the playback queue, but has already a song queued, they can be added to the _waiting room_. `none` disables this behavior and performers can have multiple songs in the queue, `optional` gives the performer a notification, and they can decide for themselves, and `forced` puts them in the waiting room every time. Once the current song of a performer leaves the queue, the song from the waiting room will be added to the queue.
* `last_song`: `none` or a time in [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601). When a song is added to the queue, and its ending time exceeds this value, it is rejected.
* `preview_duration`: Before every song, there is a short slide for the next performer. This sets how long it is shown in seconds.
* `key`: If the server, you want to connect to is in _private_ or _restricted_ mode, this will authenticate the client. Private server reject unauthenticated playback clients, restricted servers limit the searching to be _client only_.
* `mpv_options`: additional options forwarded to `mpv`.
* `show_advanced`: show advanced options in the configuration GUI.
In addition to the general config, has its own configuration under the `sources` key of the configuration.
### YouTube
Configuration is done under `sources` → `youtube` with the following settings:
* `enabled`: `true` or `false`.
* `channels`: list of YouTube channels. If this is a nonempty list, Syng will only search these channels, otherwise YouTube will be searched as a whole.
* `tmp_dir`: YouTube videos will be downloaded before playback. This sets the directory, where YouTube videos are stored.
* `start_streaming`: `true` or `false`. If `true`, videos will be streamed directly using `mpv`, if the video is not cached beforehand. Otherwise, Syng waits for the video to be downloaded.
### S3
Configuration is done under `sources` → `s3` with the following settings:
* `enabled`: `true` or `false`.
* `extensions`: List of extensions to be searched. For karaoke songs, that separate audio and video (e.g. CDG files), you can use `mp3+cdg` to signify, that the audio part is a `mp3` file and the video is a `cdg` file. For karaoke songs, that do not separate this (e.g. mp4 files), you can simply use `mp4`.
* `endpoint`: Endpoint of the s3.
* `access_key` Access key for the s3.
* `secret_key`: Secret key for the s3.
* `secure`: If `true` uses `ssl`, otherwise not.
* `bucket`: Bucket for the karaoke files.
* `index_file`: Cache file, that contains the filenames of the karaoke files in the s3.
* `tmp_dir`: Temporary download directory of the karaoke files.
### Files
Configuration is done under `sources` → `files` with the following settings:
* `enabled`: `true` or `false`.
* `extensions`: List of extensions to be searched. For karaoke songs, that separate audio and video (e.g. CDG files), you can use `mp3+cdg` to signify, that the audio part is a `mp3` file and the video is a `cdg` file. For karaoke songs, that do not separate this (e.g. mp4 files), you can simply use `mp4`.
* `dir`: Directory, where the karaoke files are stored.
