How do I get a byte[] of the camera frame in unity?

Question

I am relatively new to Unity. I was wondering how I could get the byte[] frame of the virtual main camera in Unity.

I couldn't find any tutorials online?

You can use RenderTexture for this:

• Create render texture
• Set it as target texture
• Render the current camera view to this texture
• Set the camera's render texture to null if it is not needed
• Create Texture2d
• Read data to the created Texture2d (example can be found here)
• Get bytes from your Texture2d
