Profiler.EmitFrameMetaData

Parameters

Description

Write metadata associated with the current frame to the Profiler stream.

Use EmitFrameMetaData to write arbitrary binary data to the profiler stream. Data must contain only blittable types.

using UnityEngine.Profiling;

public class Example
{
    public struct TextureInfo
    {
        public int format;
        public int w;
        public int h;
    }

    public static readonly Guid MyProjectId = new Guid("7E1DEA84-51F1-477A-82B5-B5C57AC1EBF7");
    public static readonly int TextureInfoTag = 0;
    public static readonly int TextureDataTag = 1;

    [Conditional("ENABLE_PROFILER")]
    public void EmitTextureToProfilerStream(Texture2D t)
    {
        if (!Profiler.enabled)
            return;
        TextureInfo textureInfo = new TextureInfo() { format = (int)t.format, w = t.width, h = t.height };
        NativeArray<byte> textureData = t.GetRawTextureData<byte>();
        Profiler.EmitFrameMetaData(MyProjectId, TextureInfoTag, new[] { textureInfo });
        Profiler.EmitFrameMetaData(MyProjectId, TextureDataTag, textureData);
    }
}

Note:
Writing large chunks of data might increase the Profiler's overhead and memory usage. Always check if Profiler is enabled before generating data. When possible, write data in small chunks to reduce memory usage.
