getDisplayMedia returning undefined in macos.

[b4s36t4]

I've trying to get the screen recording of my system through the tauri, but When I navigator doesn't even have the MediaDevices object.

Can anyone please help me to get the screen in macos?

Any ideas to implement feature like 'desktopCapturer' in electron?

Please follow the issue template and provide all information.

May we know your os?

I suspect macos so i’ll give a quick hint;
This is a security thing (specially in dev build, as you need a custom plist to the app)

add this in your Cargo.toml under dependencies;

embed_plist = "1.2.0"

add this is to the top of your main.rs

#[cfg(debug_assertions)]
#[cfg(target_os = "macos")]
embed_plist::embed_info_plist!("../Info.plist");

Then create a sample plist in the root of src-tauri (This will ask permission to access your camera and microphone.)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>NSCameraUsageDescription</key>
	<string>Request camera access for WebRTC</string>
	<key>NSMicrophoneUsageDescription</key>
	<string>Request microphone access for WebRTC</string>
</dict>
</plist>

Then all should works as supposed

For release build you need a custom plist.

Thanks @lemarier. Will check it.!

We need to document this or maybe help users define their plist file.

I wrote an Electron App that captures video from a USB capture card. I am currently in the process of porting it to Tauri. But still having issues and getting the grasp of when to use rust and js. I am a full JS dev.
Capture-Card-Viewer

I based the idea off Firship's 10 minute electron project on youtube. You can use the example from there.

This does not work for me and it throws the following error:

    = note: this error originates in the macro `$crate::embed_info_plist_bytes` which comes from the expansion of the macro `tauri::generate_context` (in Nightly builds, run with -Z macro-backtrace for more info)

any solutions?

So it seems that after creating an Info.plist on the src-tauri folder it gets implemented automatically.
Any *.entitlements files are not getting imported though when added to the configuration file:
Release.entitlements

tauri.conf.json

  "tauri": {
    "bundle": {
      "macOS": {
        "entitlements": "Release.entitlements",
      }
   }

and when trying to use something like:

    await navigator.mediaDevices.getDisplayMedia({
      audio: false,
      video: true
    })
      .then(stream => console.log(stream))
      .catch(e => console.log(e));

on webkit returns:

NotAllowedError: The request is not allowed by the user agent or the platform in the current context, possibly because the user denied permission.

and on the server:

+++     0x600000440540  0       1       341697610581666

as such, there is no way to capture the screen.
This seems to be a Wry problem not being able to display the screen selection dialogue.
It works on latest safari.

Remove below 3 lines from main.rs should work

#[cfg(debug_assertions)]
#[cfg(target_os = "macos")]
embed_plist::embed_info_plist!("../Info.plist");
