Zoom Remote Share

Windows-first local playback app for sending media into Zoom through a virtual camera and virtual audio device. The solution contains:

• RemoteShare.Desktop: WPF shell with WebView2, tray behavior, native file/folder import, local settings.
• RemoteShare.Host: local ASP.NET Core host that serves the UI and coordinates playback.
• RemoteShare.Core: shared media library and playback state logic.

Requirements

• Windows 10/11
• .NET 8 SDK
• Python 3 available on PATH
• ffprobe available on PATH
• OBS Virtual Camera
• VB-CABLE or another compatible virtual audio device

Run locally

dotnet build ZoomRemoteShare.sln
dotnet run --project src\RemoteShare.Desktop\RemoteShare.Desktop.csproj

The desktop app starts the local host on http://127.0.0.1:5015/ and opens the embedded UI automatically.

Security model

• The host is local-only and now requires a per-run access token for API calls.
• The desktop shell passes that token via headers for native imports and via a bootstrap URL for the embedded browser.
• Imported files and folders must resolve inside the configured library root or the remembered sources stored in %AppData%\ZoomShareRemote\desktop-settings.json.
• CORS is restricted to localhost and 127.0.0.1 on the local host port.

Desktop settings

Settings are stored in %AppData%\ZoomShareRemote\desktop-settings.json.

• libraryRootPath: optional base library folder scanned recursively on host start.
• preferredAudioDeviceContains: render-device name hint, default CABLE Input.
• rememberedSources: file and folder imports that remain available across restarts.

Helpful scripts

• scripts\install-vb-cable.ps1: downloads and launches the VB-CABLE installer.
• scripts\preview-virtual-camera-live.ps1: previews the OBS Virtual Camera feed.
• scripts\preview-virtual-mic-live.ps1: previews a virtual mic feed. Override device names with -DeviceNames.
• scripts\remove-audiorelay.ps1: removes AudioRelay if legacy virtual devices are still installed.
