setup_deeplink_handler never called — old handle removed
lib.rs (line 3537) still calls deeplink_actions::handle(&app_handle, event.urls()), which was the function this PR deleted. The replacement function setup_deeplink_handler is never wired up in lib.rs. This means:
- The codebase will not compile —
deeplink_actions::handleno longer exists. - Even if you fix the symbol, none of the new deeplink routes would ever fire because
setup_deeplink_handleris never called.
The lib.rs setup block needs to be updated to call deeplink_actions::setup_deeplink_handler(app.clone()) instead of the inline on_open_url closure.

**`setup_deeplink_handler` never called — old `handle` removed**
`lib.rs` (line 3537) still calls `deeplink_actions::handle(&app_handle, event.urls())`, which was the function this PR **deleted**. The replacement function `setup_deeplink_handler` is never wired up in `lib.rs`. This means:

startRecording requires StartRecordingInputs argument
commands.startRecording() has the signature startRecording(inputs: StartRecordingInputs): Promise<RecordingAction> where StartRecordingInputs requires at minimum capture_target (screen / window selection) and mode. Calling it with no arguments is a TypeScript type error and will throw at runtime.
Starting a recording silently via deeplink without a target is fundamentally under-specified. Consider either:
- Opening the main window and letting the user confirm the target (the current
ShowCapWindow::Maincall in the Rust side helps here, but the command still needs arguments), or - Implementing a new
startRecordingWithDefaultsTauri command that uses the last-used or default capture target.

setMicrophoneDeviceByName / setCameraDeviceByName don't exist
Neither commands.setMicrophoneDeviceByName nor commands.setCameraDeviceByName are defined in apps/desktop/src/utils/tauri.ts. The actual commands are:
commands.setMicInput(label: string | null)for microphonecommands.setCameraInput(id: DeviceOrModelID | null, skipCameraWindow: boolean | null)for camera
Calling non-existent properties will be undefined at runtime, so await undefined(name) will throw a TypeError. Replace the calls accordingly:
// microphone
await commands.setMicInput(name);
// camera (DeviceOrModelID must be resolved from the name first, or use null to disable)
await commands.setCameraInput(name, false);Note that setCameraInput expects a DeviceOrModelID object, not a plain string, so you may need to call commands.listCameras() first to resolve the device by name.

DeeplinkHandler component is never mounted
DeeplinkHandler is defined in this file but is not imported or rendered anywhere in the app layout. The Tauri event listeners it sets up will never be registered.
The component needs to be imported and rendered in the root app layout (e.g., inside the route layout) so that the listeners are active for the full application lifetime, as the JSDoc comment states.

RecordingState and InProgressRecording are imported but never referenced in the new implementation. Rust will emit dead-code warnings, and if the crate has #![deny(unused_imports)] these become errors.

coreaudio_device_input field may not exist in system_profiler JSON
system_profiler SPAudioDataType -json returns items whose top-level keys describe physical audio devices (like "Built-in Audio") and their children list individual streams. The field coreaudio_device_input is not a standard key in this output on current macOS versions — the structure is:
{
"SPAudioDataType": [
{
"_name": "Built-in Audio",
"coreaudio_default_audio_input_device": "Yes",
"coreaudio_input_source": "Internal Microphone",
...
}
]
}Filtering by coreaudio_device_input > 0 will silently drop all devices and the user will always see the fallback list. Consider filtering by coreaudio_default_audio_input_device or coreaudio_input_source instead, or use a different enumeration approach (AVFoundation via a small Swift helper).

open(url) triggers an async OS handoff to Cap — Cap's handler runs in a separate process asynchronously. showHUD is called immediately after, so the user sees "Starting Cap recording…" even if Cap is not running or the action silently fails. The same pattern applies to pause-recording.ts, resume-recording.ts, and stop-recording.ts.
Consider using showToast with a loading state, or at minimum note in the HUD that this is a request rather than a confirmation (e.g., "Sent start-recording request to Cap"), so users aren't misled about the actual outcome.
