# MediaPipe Unity Plugin
This is a Unity (>= 2021.3) [Native Plugin](https://docs.unity3d.com/Manual/NativePlugins.html) to use [MediaPipe](https://github.com/google/mediapipe) (0.10.14).
The goal of this project is to port the MediaPipe API (C++) _one by one_ to C# so that it can be called from Unity.\
This approach may sacrifice performance when you need to call multiple APIs in a loop, but it gives you the flexibility to use MediaPipe instead.
With this plugin, you can
- Write MediaPipe code in C#.
- Run MediaPipe's official solution on Unity.
- Run your custom `Calculator` and `CalculatorGraph` on Unity.
- :warning: Depending on the type of input/output, you may need to write C++ code.
## :smile_cat: Hello World!
Here is a Hello World! example.\
Compare it with [the official code](https://github.com/google/mediapipe/blob/cf101e62a9d49a51be76836b2b8e5ba5c06b5da0/mediapipe/examples/desktop/hello_world/hello_world.cc)!
```cs
using Mediapipe;
using UnityEngine;
public sealed class HelloWorld : MonoBehaviour
{
private const string _ConfigText = @"
input_stream: ""in""
output_stream: ""out""
node {
calculator: ""PassThroughCalculator""
input_stream: ""in""
output_stream: ""out1""
}
node {
calculator: ""PassThroughCalculator""
input_stream: ""out1""
output_stream: ""out""
}
";
private void Start()
{
using var graph = new CalculatorGraph(_ConfigText);
using var poller = graph.AddOutputStreamPoller("out");
graph.StartRun();
for (var i = 0; i < 10; i++)
{
graph.AddPacketToInputStream("in", Packet.CreateStringAt("Hello World!", i));
}
graph.CloseInputStream("in");
var packet = new Packet();
while (poller.Next(packet))
{
Debug.Log(packet.Get());
}
graph.WaitUntilDone();
}
}
```

## :hammer_and_wrench: Installation
This repository **does not contain required libraries** (e.g. `libmediapipe_c.so`, `Google.Protobuf.dll`, etc).\
You can download them from [the release page](https://github.com/homuler/MediaPipeUnityPlugin/releases) instead.
| file | contents |
| :-----------------------------------: | :----------------------------------------------------------------------------------------------------------------: |
| `MediaPipeUnityPlugin-all.zip` | All the source code with required libraries. If you need to run sample scenes on your mobile devices, prefer this. |
| `com.github.homuler.mediapipe-*.tgz` | [A tarball package](https://docs.unity3d.com/Manual/upm-ui-tarball.html) |
| `MediaPipeUnityPlugin.*.unitypackage` | A `.unitypackage` file |
If you want to customize the package or minify the package size, you need to build them by yourself.\
For a step-by-step guide, please refer to the [Installation Guide](https://github.com/homuler/MediaPipeUnityPlugin/wiki/Installation-Guide) on Wiki.\
You can also make use of [the Package Workflow](https://github.com/homuler/MediaPipeUnityPlugin/blob/master/.github/workflows/package.yml) on Github Actions after forking this repository.
> :warning: libraries that can be built differ depending on your environment.

### UnityEditor
Select any scenes under `Mediapipe/Samples/Scenes` and play.
### Desktop, Android, iOS
Select proper Inference Mode and Asset Loader Type from the Inspector Window.
#### Preferable Inference Mode
If you've built native libraries for CPU (i.e. `--desktop cpu`), select `CPU` for inference mode.\
When building for Android/iOS, make sure that you select `GPU` for inference mode, because `CPU` inference mode is not supported currently.
#### Asset Loader Type
The default Asset Loader Type is set to `Local`, which only works on UnityEditor.\
To run it on your devices, switch it to `StreamingAssets` and copy the required resources under [`StreamingAssets`](https://docs.unity3d.com/2022.3/Documentation/Manual/StreamingAssets.html) (if you're using `MediaPipeUnityPlugin-all.zip`, the `StreamingAssets` directory already contains them).
See [the tutorial](https://github.com/homuler/MediaPipeUnityPlugin/wiki/Getting-Started#load-model-files) for more details.
