venmic - screenshare support for pipewire

[!WARNING]
This project is not intended for standalone usage. You need a modified discord client that makes use of this.

📖 Usage

venmic can be used as node-module or as a local rest-server.

The node-module is mainly intended for internal usage by Vesktop. For a usage example, see the following Vesktop source files:

• src/main/venmic.ts
• src/renderer/patches/screenShareFixes.ts
• src/renderer/components/ScreenSharePicker.tsx: 1, 2, 3

The Rest-Server exposes three simple endpoints

• (POST) /list

  List all available applications to share.
  You can optionally define a JSON-Body containing all the props the listed nodes should have (i.e. ["node.name"]).

• (POST) /link

  <blockquote> Expects a JSON-Body in the following form: <pre lang="json"> { "include": [ { "node.name": "Firefox" } ], "exclude": [ { "node.name": "Chrome" } ] "ignore_devices": true, "workaround": [{ "node.name": "Chrome" }] } </pre>

  Depending on wether or not include or exclude are defined the behavior will change:

  • only include
    • Links nodes that match given props
  • only exclude
    • Links nodes that do not match given props
  • both include and exclude
    • Links all applications that match props in include and not those given in exclude

  The setting ignore_devices is optional and will default to true.
  When enabled it will prevent hardware-devices like speakers and microphones from being linked to the virtual microphone.

  The setting only_speakers is optional and will default to true.
  When enabled it will prevent linking against nodes that don't play to a speaker.

  The setting only_default_speakers is optional and will default to true.
  When enabled it will prevent linking against nodes that don't play to the default speaker.

  The setting workaround is also optional and will default to an empty array.
  When set, venmic will redirect the first node that matches all of the specified properties to itself.

  </blockquote>

• (GET) /unlink

  Unlinks the currently linked application

🏗️ Compiling

🐛 Debugging

When reporting an issue please make sure to set the environment variable VENMIC_ENABLE_LOG.

If said variable is set venmic will output a lot of useful information to stdout and a log-file which can be found in ~/.local/state/venmic/venmic.log.

It is highly recommended to include this log file in your issue report otherwise we may not be able to help you!
