Screen capture in multi-camera (use multi thread)

[kmmun1]

 

Hello unigine :D

We are trying to screen capture in multi-camera (every frame)

• environment
  • CPU : i9-9900k
  • GPU : RTX-3090 
  • Unigine Version : will be most recent version
  • * PC : maybe 5 or more computer (we also consider parallel computing)

 

We tried it in unity system, but its framerate was too low.

We also tried multi-thread but the unity camera component was only accessible from the main thread.

Additionally, our world have many cameras.

 

our codes in unity C# was like :

```

Update()

{

Capture1(); // start in thread 1

Capture2(); // start in thread 2

…

}

Capture1()

{

RenderTexture rt = new RenderTexture(width, height, 24);

camera1.targetTexture = rt;

Texture2D screenShot = new Texture2D(width, height,     TextureFormat.RGB24, false);

camera1.Render();

screenShot.ReadPixels(new Rect(0, 0, width, height), 0, 0);

SaveToPNG(camera1); // will be ffmpeg video

…

}

```

Can unigine engine use multi-thread with multi camera capture?

if have any samples or insight, please let us know

Thank you!

Hello!

We noticed that a similar feature exists in Unigine engine : Video grabber

 

Can we use this feature (video grabber) with multi camera?

and can we use it in runtime(not editor, in play)?

 

Your response would be appreciated

Thank you!
